Bravo: A Favro SDK with full Typescript support and tons of convenience features. By Butterscotch Shenanigans
Butterscotch Shenanigans Presents:
Favro is an amazing project management tool and a great way to centralize all kinds of workflows. However, Favro's integrations with external tools and services, and its own internal automations, are limited.
Fortunately, Favro provides an HTTP API and Webhooks so developers can fill in those gaps themselves. Unfortunately, using raw HTTP APIs is unpleasant and time-consuming. That's where Bravo comes in!
Butterscotch Shenanigans® and Bravo (this project) are not affiliated with Favro.
💡 Note: Bravo is in active development and may change substantially with any release. Check the changelog before updating!
💥 Warning: Automations can do a lot of damage if something goes wrong, and we can't guarantee anything. Before using Bravo in your production Favro Organizations, test your code on a separate Favro Organization made just for testing. Have a plan for how to recover from data loss or other errors!
See the Roadmap for which Favro API features are implemented, planned, or backburnered. If you can't find what you need, learn how to make your own changes.
Another great way to contribute is to upvote the bugs and features that we need Favro to address in order to make their API more robust and useful. Here's the list of those most relevant to Bravo, and to Favro automation in general:
Install from npm:
npm install -g @bscotch/bravo
Then import Bravo into your Node project, instance a Bravo client, and you're all set!
// ESM-style (Typescript)
import {BravoClient} from '@bscotch/bravo';
// -or-
// CommonJS-style (regular Node)
const {BravoClient} = require('@bscotch/bravo');
// Create a new Bravo Client, then start talking to Favro with it!
const bravoClient = new BravoClient({
token:'your-token',
userEmail: 'your-favro-account-email',
organizationId:'your-organization-id',
});
To have Bravo access Favro on your behalf, you'll need to provide it with the credentials listed below. You can do so via environment variables as shown here, or directly when instancing the Bravo client as shown in the example above:
FAVRO_TOKEN: Your Favro API token. To create one, go to your Profile, then "API Tokens" → "New API Token".FAVRO_USER_EMAIL: Your Favro account email.FAVRO_ORGANIZATION_ID: The Organization ID that you are targeting. You can get your Organization ID from the URL when using Favro in a browser. Favro URLs look like this: favro.com/organization/{organizationId}.Bravo contains full Typescript typings and TSDoc annotation for the data structures returned by the Favro API. The types are importable and can be used separately from Bravo. Types are organized in nested namespaces to keep them organized, and to keep from polluting the global search-scope for autocomplete services in your IDE.
The root FavroApi namespace is exported at the entrypoint of this package, so you can import it along with the BravoClient:
import {BravoClient, FavroApi} from '@bscotch/bravo';
// Create aliases to make using the more deeply nested
// typings easier to access.
type CardModel = FavroApi.Card.Model;
As long as your IDE has good Typescript support, you should be able to quickly navigate the FavroApi namespace to find the types you need.
In this section you'll find examples of common things you might want to do with the Favro API via Bravo.
The Bravo Client is the central tool for interacting with Favro. It has methods for all of the core Favro API functionality, though many of those methods return instances of other Favro objects (Widgets, Cards, Custom Fields, etc). Those other hydrated objects have convenience methods to make it even easier to work with the Favro API.
const {BravoClient} = require('@bscotch/bravo');
const bravoClient = new BravoClient({
token:'your-token',
userEmail: 'your-favro-account-email',
organizationId:'your-organization-id',
});
If you know the ID of the Widget you want to add it to, create the Card directly from the Client method:
const card = await bravoClient.createCard({
widgetCommonId: 'the-widget-id',
name: 'Talk to so-and-so',
detailedDescription: 'We need to maximize synergy.'
});
You can also create new Cards from a Widget instance:
// Find the Widget you want to add a Card to
const widget = await bravoClient.findWidgetByName('My To Do List');
// Create the new Card
const card = await widget.createCard({
name: 'Talk to so-and-so',
detailedDescription: 'We need to maximize synergy.'
});
Reflecting how the Favro API works, what you think of as a single Card is actually a separate Card Instance per Widget that the Card lives on, each with its own data.
There are many ways to find cards. The narrower you scope the request the better, and starting with a Widget is the best way since some Card data is Widget-scoped.
Find all cards on a Widget:
const cards = await bravoClient.listCardInstances({widgetCommonId: 'the-widget-id'});
// or, if you already have a Widget instance:
const cards = await widget.listCardInstances();
Find all instances of a Card using the Card's index (the one shown in the Favro app):
const cardInstances = await bravoClient.findCardInstancesBySequentialId(1234);
Find a single instance of a Card based on its Widget-specific ID:
const cardInstances = await bravoClient.findCardInstanceByCardId('the-cardId');
All Cards have a handful of built-in fields. You can update these one at a time on a card via a BravoCard instance's helper methods:
await card.updateName('new name');
await card.updateDescription('new description');
await card.update();
Update a bunch of fields at the same time to reduce API calls. You can do this by creating a raw update object, or by using an "Update Builder" as a helper to create such an object. You can even re-use an Update Builder instance to update other Cards!
// Send a raw multi-field update via the Client.
// Your IDE will help you fill this out correctly if
// it supports Typescript!
await bravoClient.updateCardInstanceByCardId('the-card-id', {
name: 'A new name!',
detailedDescription: 'A new description!'
});
// Find a user to assign in the batch update
const assignee = await bravoClient.findMemberByName('Scam Likely');
// Use the update-builder to create and send an update
// that covers multiple built-in fields.
const updateBuilder = card.createNewUpdateBuilder();
updateBuilder
.assign([assignee])
.setStartDate(new Date())
.addTagsByName(['todo'])
.archive();
// Submit the update-builder's changes
await card.update(updateBuilder);
// Update another card the same way
await someOtherCard.update(updateBuilder);
// Provide a file name and the raw data
await card.attach('some-data.txt', "Ooooh, a text file!");
// Or, provide a path to a local file to upload
await card.attach('path/to/a/file.txt');
Favro signs webhooks with the secret you provide during their creation. The BravoWebhookDefinition class has a method to validate the signature of a webhook:
import {BravoEntities} from '@bscotch/bravo';
// Quick function alias to cut that path down a bit
const isValidWebhookSignature = BravoEntities.BravoWebhookDefinition.isValidWebhookSignature;
// Depending on how you capture the webhook event,
// you'll need to get the signature from the HTTP headers.
const signature = webhookHeaders['x-favro-webhook'];
// The payload from an outgoing webhook includes a `payloadId` field.
const payloadId = webhookPayload.payloadId;
const secret = 'your-secret';
const url = 'the-webhook-postTo-url';
const isValid = isValidWebhookSignature(
url,
secret,
payloadId,
signature,
);
Bravo Clients cache data to reduce API calls and improve performance. Caching is always a double-edged sword -- whenever you need to guarantee that the data returned by Bravo reflects exactly what is stored by Favro, you'll want to clear the client's cache.
Cards have their own mechanism to ensure they are up-to-date, since they are the type of entity for which you'll most likely want to ensure that.
// Clear ALL caches. Only clears the cache for subsequent Bravo method calls.
// (If you have stored some value in a variable it will not necessarily be cleared.)
bravoClient.clearCache();
// Update the local data for a single card
await card.refresh();
To help diagnose problems in various contexts, Bravo provides a few useful mechanisms for logging.
BravoClient.console object, you can also provide that object as an option when setting up your BravoClient. You can use this with custom loggers, or to divert logs to a file or other I/O mechanism.DEBUG environment variable. Bravo uses the popular debug package for this, with the following namespaces:
bravo:*: Everything below.bravo:http:*: HTTP requests and responses (maximally verbose)bravo:http:basic: HTTP requests and responses (simple summaries of requests and responses, like URLs, methods, and status codes)bravo:http:headers: Request and response headers (WARNING: will include your API Token!)bravo:http:bodies: Request and response bodies (extremely verbose)bravo:http:stats: Summary of requests made, logged after each request, including Favro API rate limit information.The Favro API gives us access to some of the underlying data models used by Favro. While not exactly unintuitive, it is tricky to figure out how everything works together and what Favro's terms and names mean.
Below is a summary of how it all comes together.
The term "Collection" is used the same way in the webapp and API. A Collection is essentially a dashboard that contains Widgets, and Widgets can live in multiple Collections.
A Favro Board (e.g. a KanBan board or Backlog) is called a "Widget" in the Favro API.
⚠ The API does not have any access to the "Views" concept that we can use via the UI (e.g. to create Sheet and Kanban views on the same Board/Widget).
A Widget has "Columns", which have a narrower meaning than you might expect: each Column corresponds to one value from the "Status" field that is created when you make a new Widget via the GUI. In other words, "Column" and "Status" are interchangeable.
💡 Favro's Webhooks are attached to Columns: Webhooks only trigger for registered events occurring on their associated Columns.
⚠ While the default Status field is synonymous with "Columns", that is not true for custom Status fields! Custom Status fields are their own completely separate thing (discussed below).
A Card can exist in multiple Widgets at once. Favro models this by saying that a Card is "instanced" separately on each Widget. Cards have multiple identifiers acting differently on the global vs. "instance" scopes:
| Identifier Name | Scope | Purpose |
|---|---|---|
cardCommonId | Global | Identifying a Card |
cardId | Per Widget | Identifying a Card instance |
sequentialId | Global | Human-friendly id (for URLs) |
When you list Cards in a Widget-level scope (e.g. by limiting the search to a specific Widget), you'll get exactly one instance of each returned Card.
When you list Cards in a global-level scope (e.g. by filtering on sequentialId or cardCommonId, or otherwise not filtering by Widget or forcing uniqueness), you can end up getting multiple near-identical copies of the same Card! One per Widget that the Card is "instanced" on.
Many of the Card's data is completely identical in each instance. Only the Widget-specific data changes, which is largely about position information within the Widget. Example per-Widget Card data (non-exhaustive):
| Card Instance Field | Meaning |
|---|---|
widgetCommonId | The parent Widget's ID (for this Card instance) |
columnId | The identifier for the Status/Column this instance is in on the parent Widget |
parentCardId | If the card has a parent on the Widget (a la Sheet-view), the parent Card's Widget-specific cardId |
listPosition | The index position of the Card on the Widget |
timeOnBoard | How long the Card has been on the Widget |
archived | Whether or not the Card is archived on its parent Widget |
💡 To get all Board Statuses for a Card, you would need to do a search using a global identifier for that card and then loop through all returned instances.
All cards come with a handful of fields by default. These fields are global (not Widget-specific), and include:
name: The title/name of the card (the part you fill in first when making a new one)detailedDescription: The body of the card, as either Markdown or some sort of sad text file with Markdown removedcardCommonId: The globally unique identifier for this cardtags: Identifiers for tags used on this card (tags are global)sequentialId: An incrementing numeric identifier, used for URLsstartDate: The work start-date for the carddueDate: The work due-date for the cardassignments: Who is assigned, and whether they've marked themselves "complete"attachments: List of files attached and their URLscustomFields: While this field is on every card, its values depend on what data has been attached to the card via Custom Fields (see below)favroAttachments: A list of Favro data objects attached to the card (like other cards and Widgets, shown as embeds in the body)⚠ Custom Field data from the Favro API cannot be filtered by scope and does not contain scope information, unlike what you see in the Favro UI. This makes working with Custom Fields via the API (and Bravo) difficult. Upvote the associated Favro Feature request!
The idea of "Custom Fields" is a bit confusing, since the Favro GUI doesn't make it clear which fields are built-in, or that the default "Status" field is a totally different kind of thing (a collection of "Columns"). Further, "Custom Fields" overlap many of the built-ins in type: you can have a Custom Status Field, or a Custom Members field, and so on.
All fields that are neither the build-ins nor the Widget-specific "Status" (Column) fields are "Custom Fields".
In the GUI you can change a Custom Field's visibility and scope, and when you open a Card GUI you'll see all in-scope (global-, collection-, and widget-specific) Custom Fields shown, even for fields that are not yet set on that specific card. This makes it easy to figure out which field is which when using the app.
When using webhooks or the public API, however, all custom fields are global and they contain no information to help determine their scope. In other words, if any two of your (likely hundreds of) custom fields have the same name, you will not be able to tell them apart in the data returned by the Favro API.
This problem is exacerbated by the facts that:
Collectively, these prevent you from using existing Cards (fetched while narrowing the search scope to a specific Widget) to infer what fields are associated with a given Widget.
Currently, the best way to find Custom Field identifiers for use by the Favro API (or Bravo) is to use a browser's dev tools in the web-app. For example, by using the browser's "Inspect element" on a Custom Field shown inside a card, you can find its ID in the HTML element's id field.
Webhooks created via the API are assigned to a specific Widget, and within that Widget they can monitor any subset of the columns (statuses). It isn't completely obvious when these will trigger from the docs, so here's what I've found via trial and error:
Card moved: When a Card's status changes to one of the monitored statuses.
Card created: When a Card is created in a monitored column.
Card committed: When a Card is added to a Board.
Card updated: Data on a Card has been updated.
Card moved event is also triggered.Card deleted: A Card is deleted within a monitored column.Note that if changes are made quickly via the UI, e.g. rapidly switching from one Status to another, it looks like only the last change is triggered. This could be due either to a delay in the Favro UI sending the request, or to some deduping process in Favro's backend.
Some lessons learned while building Bravo.
Favro's API rate limits are quite strict and differ by plan tier. At the time of writing, based on the pricing page and my experience using the API, the limits appear to be:
| Tier | Requests/Hour |
|---|---|
| Free (trial) | 100 |
| Lite | 100 |
| Standard | 1000 |
| Enterprise | 10000 |
Rate limits appear to be per user-organization pair. It is easy to hit the lower limits even with fairly light automation, since you'll often need to make multiple requests to collect all of the data you need.
⚠ The Favro API has extremely limited search functionality. Upvote the feature request!
The Favro API does provide some filtering options, e.g. to restrict the "get Cards" endpoint to a specific Widget, but there is no way to further restrict by any content of the cards themselves (e.g. no text search on the name/description fields, nor filtering by assigned user, nor tags, etc).
To find something via the API then requires an exhaustive search followed by local filtering. Bravo adds some convenience methods for things like finding a card by name, but it does so by doing an exhaustive search behind the scenes.
Bravo does some caching and lazy-loading to reduce the impact of this on the number of API requests it makes, but the end result is always going to be that search functionality in Bravo has to consume a lot of API requests, especially if you have a lot of stuff in Favro.
Favro's API documentation for Webhooks includes sample data for all of the type of events that can trigger webhooks. However, for outgoing webhooks set in the UI (via the per-board "Automations" menu), the only data sent are a payload identifier and the current card data. There is no way to obtain information about the state of the card prior to the event, nor any way to tell what event actually occurred.
Upvote the request to fix this!
Cards have a default Members field, and also allows for Custom Members fields. You'll notice that, via the Favro webapp, if you click the "Mark as complete" button you'll get a checkmark next to your avatar in every Members-type field. (And all will be unchecked if you then mark as incomplete.) But via the API, you mark a user "complete" via the built-in or via the Custom Members field.
So what happens when you mark a user as complete via the API, given the combinations of ways a user can be assigned to any subset of the default and any Custom Members fields?
⚠ Webhooks do not send Markdown. To get full Markdown content in response to a Webhook, you'll have to fetch the same card again via the API. Upvote the feature request!
Favro implements a limited subset of Markdown. Which subset seems to differ based on context (e.g. a Card description vs. a Comment).
Despite having some Markdown support, the API and Webhook data defaults to a "plaintext" format, which apparently means "strip out all Markdown". This is a particular problem for Webhooks, since there is no way to cause them to send Markdown instead.
Bravo defaults to requesting Markdown where that's possible.
Items in Favro (cards, boards, comments, custom fields, etc.) are all identified by unique identifiers. Different types of items are fetched independently, with relationships indicated by identifiers pointing to other items.
For example, if you fetch a Card from the API (or a webhook) you'll also get a list of Widget identifiers in that card, but not the data about those widgets. Similarly, a Card contains a list of its Custom Fields and corresponding values, but most of the information is in the form of Custom Field identifiers. In both cases, if you wanted to see the names or other information for those associated items, you'll need to make API requests for those specific items using their IDs and appropriate API endpoints.
Bravo tries to handle much of this for you behind the scenes.
Cards have a field called sequentialId that corresponds directly to the visible identifier shown in the Card UI, from which users can copy a card URL.
Note that the card-search Favro API endpoint allows use of sequentialId as a query parameter. They've done us a huge solid here by allowing us to use any of the following as its value while still serving up the expected card:
BSC-123).Note that all of these also appear to work for the user-friendly Card URLs (e.g. where the default URL ends with ?card=BSC-123 you could instead use ?card=123).
cardIdsFavro Cards are always return as an instance of that Card, each with its own cardId.
Despite this ID being Widget-specific, and the existence of global identifiers for Cards, most of the Favro API card endpoints use this Widget-scoped cardId. Presumably this is to prevent them having to have distinct endpoints for managing global vs. Widget-scoped properties.
💡 Create boards manually via the app to get all the features you expect from Favro.
When creating a board via the Favro API, there appears to be no way to have the resulting board work the same way as one created via the app. In particular, when creating a Kanban board the columns are not linked to a "Status" type Custom Field and there does not seem to be a way to create such a connection after the fact.There appears to be a planned fix.
There is also no way to create views using the Favro API.
