Node.js Client Library

The official Node.js binding for your favorite SparkPost APIs!

Prerequisites

Before using this library, you must have:

• A shiny new SparkPost Account, sign up for a new account or login to SparkPost
• A valid SparkPost API Key. Check out our Support Center for information on how to create API keys

Installation

npm install sparkpost

Note: Node.js versions 0.10 and 0.12 are no longer supported.

Initialization

new SparkPost(apiKey[, options]) - Initialization

• apiKey
  • Required: yes (unless key is stored in SPARKPOST_API_KEY environment variable)
  • Type: String
  • a passed in apiKey will take precedence over an environment variable
• options.origin or options.endpoint
  • Required: no
  • Type: String
  • Default: https://api.sparkpost.com:443
    Note: To use the SparkPost EU API you will need to set this to https://api.eu.sparkpost.com:443.
• options.apiVersion
  • Required: no
  • Type: String
  • Default: v1
• options.stackIdentity
  • Required: no
  • Type: String
  • An optional identifier to include in the User-Agent header. e.g. product/1.0.0
• options.headers
  • Required: no
  • Type: Object
  • set headers that apply to all requests
• options.debug
  • Required: no
  • Type: Boolean
  • Default: false
  • appends full response from request client as debug when true for debugging purposes
    Note: This will expose your api key to the client-side. Do not use in production.

Methods

Note: All methods return promises and accept an optional last argument callback. Read about how we handle callbacks and promises.

• request(options[, callback])
  • options - see request modules options
  • options.uri - can either be a full url or a path that is appended to options.origin used at initialization (url.resolve)
  • options.debug - setting to true includes full response from request client for debugging purposes
• get | post | put | delete(options[, callback])
  • options - see request options
  • Request method will be overwritten and set to the same value as the name of these methods.

Creating a SparkPost Client

Passing in an API key

const SparkPost = require('sparkpost')
const client = new SparkPost('YOUR_API_KEY')

Using an API key stored in an environment variable

//Create an env var as SPARKPOST_API_KEY
const SparkPost = require('sparkpost')
const client = new SparkPost()

Specifying non-default options

const SparkPost = require('sparkpost')
const options = {
  endpoint: 'https://dev.sparkpost.com:443'
}
const client = new SparkPost('YOUR_API_KEY', options)

Using the Node Client Library Base Object

We may not wrap every resource available in the SparkPost Client Library, for example the Node Client Library does not wrap the Metrics resource, but you can use the Node Client Library Base Object to form requests to these unwrapped resources. Here is an example request using the base object to make requests to the Metrics resource. Here is an example request using the base object to make requests to the Metrics resource.

// Get a list of domains that the Metrics API contains data on.
const options = {
  uri: 'metrics/domains'
}

client
  .get(options)
  .then((data) => {
    console.log(data)
  })
  .catch((err) => {
    console.log(err)
  })

Send An Email "Hello World" Example

Below is an example of how to send a simple email. Sending an email is known as a transmission. By using the send method on the transmissions service that's available from the SparkPost object you instantiate, you can pass in an object with all the transmission attributes relevant to the email being sent. The send method will return a promise that will let you know if the email was sent successful and if not information about the error that occurred. If a callback is passed, it will be executed.

const SparkPost = require('sparkpost')
const client = new SparkPost('<YOUR API KEY>')

// If you have a SparkPost EU account you will need to pass a different `origin` via the options parameter:
// const euClient = new SparkPost('<YOUR API KEY>', { origin: 'https://api.eu.sparkpost.com:443' });

client.transmissions
  .send({
    options: {
      sandbox: true
    },
    content: {
      from: '[e-mail]',
      subject: 'Hello, World!',
      html: "<html><body><p>Testing SparkPost - the world's most awesomest email service!</p></body></html>"
    },
    recipients: [{ address: '<YOUR EMAIL ADDRESS>' }]
  })
  .then((data) => {
    console.log('Woohoo! You just sent your first mailing!')
    console.log(data)
  })
  .catch((err) => {
    console.log('Whoops! Something went wrong')
    console.log(err)
  })
