zapier-platform-cli
Advanced tools
This is currently pre-release software! You can fill out https://zapier.typeform.com/to/Z4TZBm if you'd like early access.
Zapier is a platform for creating integrations and workflows. This CLI is your gateway to creating custom applications on the Zapier platform.
The Zapier CLI and Platform requires Node v4.3.2. We recommend using nvm to manage your Node installation.
On Mac (via homebrew):
brew install nvm
nvm install v4.3.2
nvm use v4.3.2
Welcome to the Zapier Platform! In this tutorial, we'll walk you through the process of building, testing, and deploying an app to Zapier.
To get started, first make sure that your dev environment meets the requirements for running the the platform. Once you have the proper version of Node.js, install the Zapier CLI tool.
# install the CLI globally
npm install -g zapier-platform-cli
The CLI is the primary tool for managing your apps on Zapier. With it, you can validate and test apps locally, deploy apps so they are available on Zapier, and view logs for debugging. To see a list of all the available commands, try zapier help.
Now that your CLI is installed - you'll need to identify yourself via the CLI.
# auth to Zapier's platform with your deploy key, to obtain a key contact partners@zapier.com
zapier auth
Now your CLI is installed and ready to go!
To begin building an app, use the init command to setup the needed structure.
# create a directory with the minimum required files
zapier init example-app
# move into the new directory
cd example-app
Inside the directory, you'll see a few files. package.json is a typical requirements file of any Node.js application. The one interesting dependency is the zapier-platform-core, which is what makes your app work with the Zapier Platform.
Before we go any further - we'll need to install all the dependencies for our app:
npm install
Right next to package.json should be index.js which is the entrypoint to your app. This is where the Platform will look for your app definition. Open it up in your editor of choice and let's take a look!
You'll see a few things in index.js, we'll briefly describe each here:
App definition which will be interpreted by ZapierApp definition, beforeRequest & afterResponse are hooks into the HTTP clientApp definition, resources are purely optional but convenient ways to describe CRUD-like objects in your appApp definition, triggers will describe ways to trigger off of data in your appApp definition, searches will describe ways to find data in your appApp definition, writes will desciribe ways to create data in your appLet's start with a basic trigger using a mocked API:
mkdir triggers
touch triggers/recipe.js
Now open your triggers/recipe.js and paste this:
const listRecipes = (z, bundle) => {
const promise = z.request('http://57b20fb546b57d1100a3c405.mockapi.io/api/recipes');
return promise.then((response) => JSON.parse(response.content));
};
module.exports = {
key: 'recipe',
noun: 'Recipe',
display: {
label: 'New Recipe',
description: 'Trigger when a new recipe is added.'
},
operation: {
perform: listRecipes
}
};
Now, let's return to our index.js and add two new lines of code:
require() for the triggerAppconst recipe = require('./triggers/recipe'); // new line of code!
const App = {
// ...
triggers: {
[recipe.key]: recipe // new line of code!
},
// ...
};
module.exports = App;
Now, let's add a test to make sure our code is working properly, go ahead and take a look at test/index.js and paste this:
require('should');
const zapier = require('zapier-platform-core');
const appTester = zapier.createAppTester(require('../index'));
describe('triggers', () => {
it('should load recipes', (done) => {
const bundle = {};
appTester('triggers.recipe', bundle)
.then(results => {
results.length.should.above(1);
const firstRecipe = results[0];
firstRecipe.name.should.eql('name 1');
firstRecipe.directions.should.eql('directions 1');
done();
})
.catch(done);
});
});
And you should be able to run the tests with zapier test:
zapier test
#
# triggers
# 200 GET http://57b20fb546b57d1100a3c405.mockapi.io/api/recipes
# ✓ should load recipes (312ms)
#
# 1 passing (312ms)
#
Let's say we want to let our users tweak the styles of recipes they are triggering on, a classic way to do that with Zapier is to provide a input field they can select from.
Let's re-open your triggers/recipe.js and paste this:
const listRecipes = (z, bundle) => {
const promise = z.request('http://57b20fb546b57d1100a3c405.mockapi.io/api/recipes', {
// NEW CODE
params: {
style: bundle.inputData.style
}
});
return promise.then((response) => JSON.parse(response.content));
};
module.exports = {
key: 'recipe',
noun: 'Recipe',
display: {
label: 'New Recipe',
description: 'Trigger when a new recipe is added.'
},
operation: {
// NEW CODE
inputFields: [
{key: 'style', type: 'string'}
],
perform: listRecipes
}
};
Let's tweak the test in test/index.js and paste this in:
require('should');
const zapier = require('zapier-platform-core');
const appTester = zapier.createAppTester(require('../index'));
describe('triggers', () => {
it('should load recipes', (done) => {
const bundle = {
// NEW CODE
inputData: {
style: 'mediterranean'
}
};
appTester('triggers.recipe', bundle)
.then(results => {
results.length.should.above(1);
const firstRecipe = results[0];
firstRecipe.name.should.eql('name 1');
firstRecipe.directions.should.eql('directions 1');
done();
})
.catch(done);
});
});
And now, you can run your test again and make sure you didn't break anything:
zapier test
#
# triggers
# 200 GET http://57b20fb546b57d1100a3c405.mockapi.io/api/recipes
# ✓ should load recipes (312ms)
#
# 1 passing (312ms)
#
Looking real good locally! Let's move on.
Of course, while developing a Zapier app locally is pretty easy - the end goal is usually to use it in Zapier UI with the thousands of other integrations! Since we have a working local app - deploying to Zapier is very straightforward.
First, you'll need to register your app with Zapier. This enables all the admin tooling like deployment - but also tooling we'll learn about later promotion, collaboration, and environment variables.
zapier register "Example App"
# Registering a new app on Zapier named "Example App"
#
# Confirming registation of app "Example App" - done!
# Linking app to current directory with `.zapierapprc` - done!
#
# Finished! Now that your app is registered with Zapier, you can `zapier deploy` a version!
Now, we have to deploy a version of your app - you can can have many versions of an app which simplifies breaking changes and testing in the future - for now we just need a single version deployed so let's start there.
zapier deploy
# Preparing to build and upload your app.
#
# Copying project to temp directory - done!
# Installing project dependencies - done!
# Applying entry point file - done!
# Validating project - done!
# Building app definition.json - done!
# Zipping project and dependencies - done!
# Cleaning up temp directory - done!
# Uploading version 1.0.0 - done!
#
# Build and upload complete! You should see it in your Zapier editor at https://zapier.com/app/editor now!
Now that your app version is properly deployed you can log in and visit https://zapier.com/app/editor to try creating an Zap using your app version.
Be sure to check the Requirements before you start!
First up is installing the CLI and setting up your auth to create a working "Zapier Example" application. It will be private to you and visible in your live Zap editor.
# install the CLI globally
npm install -g zapier-platform-cli
# auth to Zapier's platform with your deploy key. To obtain a key, email partner@zapier.com
zapier auth
Your Zapier CLI should be installed and ready to go at this point. Next up, we'll create our first app!
# make your folder
mkdir zapier-example
cd zapier-example
# create the needed files from a template
zapier init --template=trigger
# install all the libraries needed for your app
npm install
Note: there are plenty of templates & example apps to choose from! View all Example Apps here.
You should now have a working local app. You can run several local commands to try it out.
# run the local tests
# the same as npm test
zapier test
Next, you'll probably want to register your app and upload your version to Zapier itself so you can start testing live.
# register your app
zapier register "Zapier Example"
# deploy your app version to Zapier
zapier deploy
If you open the editor in Zapier, you should now see "Zapier Example (1.0.0)" listed and usable! We recommend using our built in watch command to iterate on the app.
# watch and sync up your local app to zapier
zapier watch
# now make changes locally, and see them reflected live in Zapier
# method calls will also be proxied and logged to stdout for convenience
Don't forget you'll need to zapier deploy to make your changes stick after any zapier watch session ends!
Go check out our full CLI reference documentation to see all the other commands!
Tip: check the Quickstart if this is your first time using the platform!
Creating an App can be done entirely locally and they are fairly simple Node.js apps using the standard Node environment and should be completely testable. However, a local app stays local until you zapier register.
# make your folder
mkdir zapier-example
cd zapier-example
# create the needed files from a template
zapier init --template=trigger
# install all the libraries needed for your app
npm install
If you'd like to manage your local App, use these commands:
zapier init --template=resource - initialize/start a local app projectzapier scaffold resource Contact - auto-injects a new resource, trigger, etc.zapier test - run the same tests as npm testzapier validate - ensure your app is validzapier describe - print some helpful information about your appIn your app's folder, you should see this general recommended structure. The index.js is Zapier's entry point to your app. Zapier expects you to export an App definition there.
$ tree .

The core definition of your App will look something like this, and is what your index.js should provide as the only export:
const App = {
// both version strings are required
version: require('./package.json').version,
platformVersion: require('zapier-platform-core').version,
// see "Authentication" section below
authentication: {
},
// see "Making HTTP Requests" section below
requestTemplate: {
},
beforeRequest: [
],
afterResponse: [
],
// See "Resources" section below
resources: {
},
// See "Triggers/Searches/Writes" section below
triggers: {
},
searches: {
},
writes: {
}
};
module.export = App;
Tip: you can use higher order functions to create any part of your App definition!
Registering your App with Zapier is a necessary first step which only enables basic administrative functions. It should happen before zapier deploy which is to used to actually expose an App Version in the Zapier interface and editor.
# register your app
zapier register "Zapier Example"
# list your apps
zapier apps
Note: this doesn't put your app in the editor - see the docs on deploying an App Version to do that!
If you'd like to manage your App, use these commands:
zapier apps - list the apps in Zapier you can administerzapier register "Name" - creates a new app in Zapierzapier link - lists and links a selected app in Zapier to your current folderzapier history - print the history of your appzapier collaborate [user@example.com] - add admins to your app who can deployzapier invite [user@example.com] - add users to try your app before promotionAn App Version is related to a specific App but is an "immutable" implementation of your app. This makes it easy to run multiple versions for multiple users concurrently. By default, every App Version is private but you can zapier promote it to production for use by over 1 million Zapier users.
# deploy your app version to Zapier
zapier deploy
# list your versions
zapier versions
# watch and sync up your local app to zapier
zapier watch
# now make changes locally, and see them reflected live in Zapier
# method calls will also be proxied and logged to stdout for convenience
If you'd like to manage your Version, use these commands:
zapier versions - list the versions for the current directory's appzapier deploy - deploy the current version the of current directory's app & version (read from package.json)zapier promote [1.0.0] - mark a version as the "production" versionzapier migrate [1.0.0] [1.0.1] [100%] - move users between versions, regardless of deployment statuszapier deprecate [1.0.0] [YYYY-MM-DD] - mark a version as deprecated, but let users continue to use it (we'll email them)zapier env 1.0.0 [KEY] [value] - set an environment variable to some valuezapier watch - continuously sync your app to the Zapier interface, creating a fast feedback loopA simple zapier deploy will only create the App Version in your editor. No one else using Zapier can see it or use it.
This is how you would share your app with friends, co-workers or clients. This is perfect for quality assurance, testing with active users or just sharing any app you like.
# sends an email this user to let them view the app in the ui privately
zapier invite user@example.com
# sends an email this user to let being an admin of the app
zapier collaborate user@example.com
Promotion is how you would share your app with every one of the 1 million+ Zapier users. If this is your first time promoting - you may have to wait for the Zapier team to review and approve your app.
If this isn't the first time you've promoted your app - you might have users on older versions. You can zapier migrate to either move users over (which can be dangerous if you have breaking changes). Or, you can zapier deprecate to give users some time to move over themselves.
# promote your app version to all Zapier users
zapier promote 1.0.1
# OPTIONAL - migrate your users between one app version to another
zapier migrate 1.0.0 1.0.1
# OR - mark the old version as deprecated
zapier deprecate 1.0.0 2017-01-01
Most applications require some sort of authentication - and Zapier provides a handful of methods for helping your users authenticate with your application. Zapier will provide some of the core behaviors, but you'll likely need to handle the rest.
Hint: You can access the data tied to your authentication via the
bundle.authDataproperty in any method called in your app.
Useful if your app requires two pieces of information to authentication: username and password which only the end user can provide. By default, Zapier will do the standard Basic authentication base64 header encoding for you (via an automatically registered middleware).
Note: if you do the common API Key pattern like
Authorization: Basic APIKEYHERE:xyou should look at the "Custom" authentication method instead.
const authentication = {
type: 'basic',
// "test" could also be a function
test: {
url: 'https://example.com/api/accounts/me.json'
}
// you can provide additional fields, but we'll provide `username`/`password` automatically
};
const App = {
// ...
authentication: authentication,
// ...
};
This is what most "API Key" driven apps should default to using. You'll likely provide some some custom beforeRequest middleware or a requestTemplate to complete the authentication by adding/computing needed headers.
const authentication = {
type: 'custom',
// "test" could also be a function
test: {
url: 'https://{{bundle.authData.subdomain}}.example.com/api/accounts/me.json'
},
fields: [
{key: 'subdomain', type: 'string', required: true, helpText: 'Found in your browsers address bar after logging in.'},
{key: 'api_key', type: 'string', required: true, helpText: 'Found on your settings page.'}
]
};
const addApiKeyToHeader = (request, z, bundle) => {
request.headers['X-Subdomain'] = bundle.authData.subdomain;
const basicHash = Buffer(`${bundle.authData.api_key}:x`).toString('base64');
request.headers.Authorization = `Basic ${basicHash}`;
return request;
};
const App = {
// ...
authentication: authentication,
beforeRequest: [
addApiKeyToHeader,
],
// ...
};
Very similar to the "Basic" authentication method above, but uses digest authentication instead of Basic authentication.
const authentication = {
type: 'digest',
// "test" could also be a function
test: {
url: 'https://example.com/api/accounts/me.json'
}
// you can provide additional fields, but Zapier will provide `username`/`password` automatically
};
const App = {
// ...
authentication: authentication,
// ...
};
TODO.
Zapier will handle most of the logic around the 3 step OAuth flow, but you'll be required to define how the steps work on your own. You'll also likely want to set your CLIENT_ID and CLIENT_SECRET as environment variables:
# setting the environment variables on Zapier.com
$ zapier env 1.0.0 CLIENT_ID 1234
$ zapier env 1.0.0 CLIENT_SECRET abcd
# and when running tests locally, don't forget to define them!
$ CLIENT_ID=1234 CLIENT_SECRET=abcd zapier test
Your auth definition would look something like this:
const authentication = {
type: 'oauth2',
test: {
url: 'https://example.com/api/accounts/me.json'
},
// you can provide additional fields for inclusion in authData
oauth2Config: {
// "authorizeUrl" could also be a function returning a string url
authorizeUrl: {
method: 'GET',
url: 'https://example.com/api/oauth2/authorize',
params: {
client_id: '{{process.env.CLIENT_ID}}',
state: '{{bundle.inputData.state}}',
redirect_uri: '{{bundle.inputData.redirect_uri}}',
response_type: 'code'
}
},
// Zapier expects a response providing {access_token: 'abcd'}
// "getAccessToken" could also be a function returning an object
getAccessToken: {
method: 'POST',
url: 'https://example.com/api/v2/oauth2/token',
body: {
code: '{{bundle.inputData.code}}',
client_id: '{{process.env.CLIENT_ID}}',
client_secret: '{{process.env.CLIENT_SECRET}}',
redirect_uri: '{{bundle.inputData.redirect_uri}}',
grant_type: 'authorization_code'
},
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}
}
};
const addBearerHeader = (request, z, bundle) => {
request.headers.Authorization = `Bearer ${bundle.authData.access_token}`;
return request;
};
const App = {
// ...
authentication: authentication,
beforeRequest: [
addBearerHeader,
]
// ...
};
A resource is a representation (as a JavaScript object) of one of the REST resources of your API. Say you have a /recipes
endpoint for working with recipes; you can define a recipe resource in your app that will tell Zapier how to do create,
read, and search operations on that resource.
const Recipe = {
// `key` is the unique identifier the Zapier backend references
key: 'recipe',
// `noun` is the user-friendly name displayed in the Zapier UI
noun: 'Recipe',
// `list` and `create` are just a couple of the methods you can define
list: {
//...
},
create: {
//...
}
};
The quickest way to create a resource is with the zapier scaffold command:
zapier scaffold resource "Recipe"
This will generate the resource file and add the necessary statements to the index.js file to import it.
A resource has a few basic properties. The first is the key, which allows Zapier to identify the resource on our backend.
The second is the noun, the user-friendly name of the resource that is presented to users throughout the Zapier UI.
After those, there is a set of optional properties that tell Zapier what methods can be performed on the resource. The complete list of available methods can be found in the Resource Schema Docs. For now, let's focus on two:
list - Tells Zapier how to fetch a set of this resource. This becomes a Trigger in the Zapier Editor.create - Tells Zapier how to create a new instance of the resource. This becomes an Action in the Zapier Editor.Here is a complete example of what the list method might look like
const listRecipesRequest = {
url: 'http://example.com/recipes'
};
const Recipe = {
//...
list: {
display: {
label: 'New Recipe',
description: 'Triggers when a new recipe is added.'
},
operation: {
perform: listRecipesRequest
}
}
};
The method is made up of two properties, a display and an operation. The display property (schema) holds the info needed to present the method as an available Trigger in the Zapier Editor. The operation (schema) provides the implementation to make the API call.
Adding a create method looks very similar.
const createRecipeRequest = {
url: 'http://example.com/recipes',
method: 'POST',
body: {
name: 'Baked Falafel',
style: 'mediterranean'
}
};
const Recipe = {
//...
list: {
//...
},
create: {
display: {
label: 'Add Recipe',
description: 'Adds a new recipe to our cookbook.'
},
operation: {
perform: createRecipeRequest
}
}
};
Every method you define on a resource Zapier converts to the appropriate Trigger, Write, or Search. Our examples
above would result in an app with a New Recipe Trigger and an Add Recipe Write.
Triggers, Searches, and Writes are the way an app defines what it is able to do. Triggers read data into Zapier (i.e. watch for new recipes). Searches locate individual records (find recipe by title). Writes create new records in your system (add a recipe to the catalog).
The definition for each of these follows the same structure. Here is an example of a trigger:
const recipeListRequest = {
url: 'http://example.com/recipes',
};
const App = {
//...
triggers: {
new_recipe: {
key: 'new_recipe', // uniquely identifies the trigger
noun: 'Recipe', // user-friendly word that is used to refer to the resource
// `display` controls the presentation in the Zapier Editor
display: {
label: 'New Recipe',
helpText: 'Triggers when a new recipe is added.'
},
// `operation` implements the API call used to fetch the data
operation: {
perform: recipeListRequest
}
},
another_trigger: {
// Another trigger definition...
}
}
};
You can find more details on the definition for each by looking at the Trigger Schema, Search Schema, and Write Schema.
There are two primary ways to make HTTP requests in the Zapier platform:
z.request() to make the requests and control the response.There are also a few helper constructs you can use to reduce boilerplate:
requestTemplate which is an shorthand HTTP request that will be merged with every request.beforeRequest middleware which is an array of functions to mutate a request before it is sent.afterResponse middleware which is an array of functions to mutate a response before it is completed.For simple HTTP requests that do not require special pre or post processing, you can specify the HTTP options as an object literal in your app definition.
This features:
{{curly}} replacement.const triggerShorthandRequest = {
method: 'GET',
url: 'http://{{bundle.authData.subdomain}}.example.com/v2/api/recipes.json',
params: {
sort_by: 'id',
sort_order: 'DESC'
}
};
const App = {
// ...
triggers: {
example: {
// ...
operation: {
// ...
perform: triggerShorthandRequest
}
}
}
};
In the url above, {{bundle.authData.subdomain}} is automatically replaced with the live value from the bundle. If the call returns a non 2xx return code, an error is automatically raised. The response body is automatically parsed as JSON and returned.
An error will be raised if the response is not valid JSON, so do not use shorthand HTTP requests with non-JSON responses.
When you need to do custom processing of the response, or need to process non-JSON responses, you can make manual HTTP requests. This approach does not perform any magic - no {{curly}} replacement, no status code checking, no automatic JSON parsing. Use this method when you need more control.
To make a manual HTTP request, use the request method of the z object:
const listExample = (z, bundle) => {
const customHttpOptions = {
headers: {
'my-header': 'from zapier'
}
};
return z.request('http://example.com/api/v2/recipes.json', customHttpOptions)
.then(response => {
if (response.status >= 300) {
throw new Error(`Unexpected status code ${response.status}`);
}
const recipes = JSON.parse(response.content);
// do any custom processing of recipes here...
return recipes;
});
};
const App = {
// ...
triggers: {
example: {
// ...
operation: {
// ...
perform: listExample
}
}
}
};
To POST or PUT data to your API you can do this:
const App = {
// ...
triggers: {
example: {
// ...
operation: {
// ...
perform: (z, bundle) => {
const recipe = {
name: 'Baked Falafel',
style: 'mediterranean',
directions: 'Get some dough....'
};
const options = {
method: 'POST',
body: JSON.stringify(recipe)
};
return z.request('http://example.com/api/v2/recipes.json', options)
.then(response => {
if (response.status !== 201) {
throw new Error(`Unexpected status code ${response.status}`);
}
});
}
}
}
}
};
Note that you need to call JSON.stringify() before setting the body.
If you need to process all HTTP requests in a certain way, you may be able to use one of utility HTTP middleware functions, by putting them in your app definition:
const addHeader = (request) => {
request.headers['my-header'] = 'from zapier';
return request;
};
const mustBe200 = (response) => {
if (response.status !== 200) {
throw new Error(`Unexpected status code ${response.status}`);
}
return response;
};
const autoParseJson = (response) => {
response.json = JSON.parse(response.content);
return response;
};
const App = {
// ...
beforeRequest: [
addHeader,
],
afterRequest: [
mustBe200,
autoParseJson,
]
// ...
};
A beforeRequest middleware function takes a request options object, and returns a (possibly mutated) request object. An afterResponse middleware function takes a response object, and returns a (possibly mutated) response object. Middleware functions are executed in the order specified in the app definition, and each subsequent middleware receives the request or response object returned by the previous middleware.
Middleware functions can be asynchronous - just return a promise from the middleware function.
Shorthand requests and manual z.request() calls support the following HTTP options:
method: HTTP method, default is GET.headers: request headers object, format {'header-key': 'header-value'}.params: URL query params object, format {'query-key': 'query-value'}.body: request body, can be a string, buffer, or readable stream.redirect: set to manual to extract redirect headers, error to reject redirect, default is follow.follow: maximum redirect count, set to 0 to not follow redirects. default is 20.compress: support gzip/deflate content encoding. Set to false to disable. Default is true.agent: Node.js http.Agent instance, allows custom proxy, certificate etc. Default is null.timeout: request / response timeout in ms. Set to 0 to disable (OS limit still applies), timeout reset on redirect. Default is 0 (disabled).size: maximum response body size in bytes. Set to 0`` to disable. Defalut is 0` (disabled).The response object returned by z.request() supports the following fields and methods:
status: The response status code, i.e. 200, 404, etc.content: The raw response body. For JSON you need to call JSON.parse(response.content).headers: Response headers object. The header keys are all lower case.getHeader: Retrieve response header, case insensitive: response.getHeader('My-Header')options: The original request options object (see above).We provide several methods off of the z object, which is provided as the first argument in all function calls in your app.
request: make an HTTP request, see "Making HTTP Requests" above. See Making HTTP Requests.console: logging console, similar to Nodejs console but logs remotely, as well as to stdout in tests. See Log SttatementsJSON: similar API to JSON built in but catches errors with nicer tracebacks.hash: Helpful handler for doing z.hash('sha256', 'my password')
errorserrors: Error classes that you can throw in your code, like throw new z.errors.HaltedError('...')dehydrate: dehydrate a functiondehydrateRequest: dehydrate a requestdehydrateFile: dehydrate a fileThis payload will provide user provided data and configuration data.
authData - user provided authentication data, like api_key or even access_token if you are using oauth2 [(read more on authentication)[#authentication]]inputData - user provided configuration data, like listId or tagSlug as defined by inputData. For example:{
createdBy: 'Bobby Flay'
style: 'mediterranean'
}
inputDataRaw - like inputData, but before rendering {{curlies}}.{
createdBy: '{{chef_name}}'
style: '{{style}}'
}
Apps can define environment varialbes that are available when the app's code executes. They work just like environment variables defined on the command line. They are useful when you have data like an OAuth client ID and secret that you don't want to commit to source control. Environment variables can also be used as a quick way to toggle between a a staging and production environment during app development.
It is important to note that variables are defined on a per-version basis! When you deploy a new version, the existing variables from the previous version are copied, so you don't have to manually add them. However, edits made to one version's environment will not affect the other versions.
To define an environment variable, use the env command:
# Will set the environment variable on Zapier.com
zapier env 1.0.0 MY_SECRET_VALUE 1234
You will likely also want to set the value locally for testing.
export MY_SECRET_VALUE=1234
To view existing environment variables, use the env command.
# Will print a table listing the variables for this version
zapier env 1.0.0
Within your app, you can access the environment via the standard process.env - any values set via local export or zapier env will be there.
For example, you can access the process.env in your perform functions:
const listExample = (z, bundle) => {
const httpOptions = {
headers: {
'my-header': process.env.MY_SECRET_VALUE
}
};
return z.request('http://example.com/api/v2/recipes.json', httpOptions);
};
const App = {
// ...
triggers: {
example: {
// ...
operation: {
// ...
perform: listExample
}
}
}
};
TODO: describe rough logging outline.
To manually print a log statement in your code, use z.console:
z.console.log('Here are the input fields', bundle.inputData);
The z.console object has all the same methods and works just like the Node.js Console class - the only difference is we'll log to our distrubuted datastore and you can view them via zapier logs (more below).
Zapier automatically logs all HTTP requests (as long as you use z.request() or shorthand request objects).
To view the logs for your application, use the zapier logs command. There are two types of logs, http (logged automatically by Zapier on HTTP requests) and console (manual logs via z.console.log() statements). To see the HTTP logs do:
zapier logs --type=http
To see detailed http logs including headers, request and response bodies, etc, do:
zapier logs --type=http --detailed
To see your z.console logs do:
zapier logs --type=console
For more advanced logging options including only displaying the logs for a certain user or app version, look at the help for the logs command:
zapier help logs
You can write unit tests for your Zapier app that run locally, outside of the zapier editor. You can run these tests in a CI tool like Travis.
We recommend using the Mocha testing framework. After running
zapier init you should find an example test to start from in the test directory.
To
// we use should assertions
const should = require('should');
const zapier = require('zapier-platform-core');
// createAppTester() makes it easier to test your app. It takes your
// raw app definition, and returns a function that will test you app.
const appTester = zapier.createAppTester(require('../index'));
describe('triggers', () => {
describe('new recipe trigger', () => {
it('should load recipes', (done) => {
// This is what Zapier will send to your app as input.
// It contains trigger options the user choice in their zap.
const bundle = {
inputData: {
style: 'mediterranean'
}
};
// Pass appTester the path to the trigger you want to call,
// and the input bundle. appTester returns a promise for results.
appTester('triggers.recipe', bundle)
.then(results => {
// Make assertions
results.length.should.eql(10);
const firstRecipe = results[0];
firstRecipe.name.should.eql('Baked Falafel');
done();
})
.catch(done);
});
});
});
To run all your tests do:
zapier test
When running a unit test via zapier test, z.console statements print to stdout. To see the HTTP logs when running tests do:
zapier test --log-to-stdout
To also see the detailed HTTP logs do:
zapier test --log-to-stdout --detailed-log-to-stdout
