node-mailchimp

Mailchimp api wrapper for v3 of the mailchimp api, with batch handling. Supports both promise and callback handling.

var Mailchimp = require('mailchimp-api-v3')

var mailchimp = new Mailchimp(api_key);

//Callback style
mailchimp.get({
  path : '/lists/id1'
}, function (err, result) {
  ...
})

//Promise style
mailchimp.get({
  path : '/lists/id1'
})
.then(function (result) {
  ...
})
.catch(function (err) {
  ...
})

seamless batch calls, with polling and unpacking of results

//Callback style
mailchimp.batch([
{
  method : 'get',
  path : '/lists/id1'
},
{
  method : 'get',
  path : '/lists/id2'
}], function (err, results) {
  //results[0] same as result in previous example
})

//Promise style
mailchimp.batch([
{
  method : 'get',
  path : '/lists/id1'
},
{
  method : 'get',
  path : '/lists/id2'
}])
.then(function (results) {
  //results[0] same as result in previous example
})
.catch(function (err) {
  ...
})

Why

Version 3 of the mailchimp api is an excellent RESTful api. This library makes it easy to integrate mailchimp using their own api documentation.

This library also supports easy usage of the mailchimp batch operations, enabling them to be used just as the standard api calls.

Installation

$ npm install mailchimp-api-v3

Usage

For information on the possible calls, refer to the mailchimp api v3 documentation: http://developer.mailchimp.com/documentation/mailchimp/reference/overview/

Promise support

In all calls you can omit the callback, and a promise will be returned instead.

Initialization

var Mailchimp = require('mailchimp-api-v3')

var mailchimp = new Mailchimp(api_key);

Standard Calls

mailchimp.request({
  method : 'get|post|put|patch|delete',
  path : 'path for the call, see mailchimp documentation for possible calls',
  path_params : {
    //path parameters, see mailchimp documentation for each call
  },
  body : {
    //body parameters, see mailchimp documentation for each call
  },
  query : {
    //query string parameters, see mailchimp documentation for each call
  }
}, callback)

path can be given either exactly as in the mailchimp documentation ("/campaigns/{campaign_id}") and path_params specifying id values, or as a string with path parameters already substituted, and no path_params

For each request method, convenience calls exists to make common calls:

mailchimp.get(path, [query], [callback])
mailchimp.post(path, [body], [callback])
mailchimp.put(path, [body], [callback])
mailchimp.patch(path, [body], [callback])
mailchimp.delete(path, [callback])

This allows shorthand forms like:

mailchimp.get('/lists')
.then(function(results) {
  ...
})
.catch(function (err) {
  ...
})

mailchimp.post('/lists/id/members', {
  email_address : '...',
  status : 'subscribed'
  ...
})
.then(function(results) {
  ...
})
.catch(function (err) {
  ...
})

Batch Calls

var calls = [
{
  method : 'post',
  path : '/lists/id1/members'
  body : {
    email_address : '1@example.com',
    status : 'subscribed'
  }
},
{
  method : 'post',
  path : '/lists/id1/members'
  body : {
    email_address : '2@example.com',
    status : 'subscribed'
  }
}]


mailchimp.batch(calls, callback, {
  wait : true,
  interval : 2000,
  unpack : true,
})

batch takes an array of call options, exactly as used in the standard call.

• wait whether or not to wait for the batch command to finish, defaults to true
• interval if wait is true, the interval to poll for the status of the batch call, defaults to 2000ms
• unpack if wait is true, whether or not to get and unpack the results of the batch operation, and return the response bodies.
• verbose if wait is true, whether or not to log progress to the console

BatchWait

mailchimp.batchWait(batch_id, callback, {
  interval : 2000,
  unpack : true,
})

If you call batch with wait : false, you can use the returned batch id to resume pooling and unpacking the results at a later time. This also allows you to "reconnect" to a batch operation after a crash or similar.

Single operation batch

If you pass a single operation, instead of an array to batch, the result will be the same as if you ran the operation without batch. This is very useful if you want to make calls without paging, where a normal call would take to long, and likely time out.

mailchimp.batch({
  method : 'get',
  path : '/lists/id/members',
  query : {
    count  : 10000000000,
  }
}, function (err, result) {
  //result is the same as a normal .get request
})
