MessageBird REST API for Node.js

This repository contains the open source Node.js client for MessageBird's REST API. Documentation can be found at: https://developers.messagebird.com

Requirements

• Sign up for a free MessageBird account
• Create a new access_key in the developers section
• MessageBird REST API for Node.js requires Node.js >= 0.10 or io.js

Installation

npm install messagebird

Usage

We have put some self-explanatory examples in the examples directory, but here is a quick breakdown on how it works. Let's go ahead and initialize the library first. Don't forget to replace <YOUR_ACCESS_KEY> with your actual access key.

var messagebird = require('messagebird')('<YOUR_ACCESS_KEY>');

Nice! Now we can send API requests through node. Let's use getting your balance overview as an example:

// Get your balance
messagebird.balance.read(function (err, data) {
  if (err) {
    return console.log(err);
  }
  console.log(data);
});

// Result object:
{
  payment: 'prepaid',
  type: 'credits',
  amount: 42.5
}

Or in case of an error:

{ [Error: api error]
  errors: [
    {
      code: 2,
      description: 'Request not allowed (incorrect access_key)',
      parameter: 'access_key'
    }
  ]
}

Notes

Messaging and Voice API use different pagination semantics:

Messaging API uses limit and offset params for list methods (where applicable)

// list conversations
//In this case 20 is limit and 0 is offset
messagebird.conversations.list(20, 0, function (err, response) {
  if (err) {
    return console.log(err);
  }
  console.log(response);
});

Voice API uses page and perPage params for list methods (where applicable)

// list Call Flows
// In this case 1 is page, 2 is items per page
messagebird.callflows.list(1, 2, function (err, response) {
  if (err) {
    return console.log(err);
  }
  console.log(response);
});

Verifying Signatures

We sign our HTTP requests to allow you to verify that they actually came from us (authentication) and that they haven't been altered along the way (integrity). For each HTTP request that MessageBird sends, a MessageBird-Signature and MessageBird-Request-Timestamp header is added. Signature middleware calculates a signature using the timestamp, query parameters and body then compares the calculated signature to MessageBird-Signature header. If they are not same or request expired, middleware throws an error. This way, you will know if the request is valid or not. If you want to verify request manually, you can check here. Let's use Signature middleware to verify webhooks.

var Signature = require('messagebird/lib/signature');

// Replace <YOUR_SIGNING_KEY> with your actual signing key.
var verifySignature = new Signature('<YOUR_SIGNING_KEY>');

// Retrieve the raw body as a buffer.
app.use(require('body-parser').raw({ type: '*/*' }));

// Verified webhook.
app.get('/webhook', verifySignature, function(req, res) {
    res.send("Verified");
});

Conversations Whatsapp Sandbox

To use the whatsapp sandbox you need to add "ENABLE_CONVERSATIONSAPI_WHATSAPP_SANDBOX" to the list of features you want enabled. Don't forget to replace <YOUR_ACCESS_KEY> with your actual access key.

var messagebird = require('messagebird')("<YOUR_ACCESS_KEY>", null, ["ENABLE_CONVERSATIONSAPI_WHATSAPP_SANDBOX"]);
