phaxio-api

This is an implementation of the Phaxio Fax API for node.

Features:

• properly streams your content to Phaxio, taking any arbitrary Readable stream.

• returns promises

• includes optional Express middleware for listening to callbacks from Phaxio and emitting sent events.

Install

npm install --save phaxio-api

Synopsis

var PhaxioAPI = require('phaxio-api');
var phaxio = new PhaxioAPI({ api_key: '...', api_secret: '...' });
var phoneNumber = '1235551212';

// Stream a document
phaxio.send(phoneNumber, {stream: fs.createReadStream(myFileName)})

// Stream a document with optional filename, contentType, and knownLength
phaxio.send(phoneNumber, {
  stream: anyReadableStream,
  contentType: 'application/pdf',
  filename: 'foo.pdf',
  knownLength: 1000 // This may be necessary when form-data
                    // can't tell the length of your readable stream.
});

// Send a string via phaxio's string_data options:
phaxio.send(phoneNumber, {
  string_data: 'http://example.com/some_document',
  string_data_type: 'url'
});

// All other opts get passed through to phaxio's sendFax unchanged:
phaxio.send(phoneNumber, {
  string_data: 'http://example.com/some_document',
  string_data_type: 'url',
  batch: 'true',
  batch_delay: '60'
});

// `send` returns a promise that resolves if the sendFax call succeeded.
phaxio.send(phoneNumber, {stream: fs.createReadStream(myFileName)}).then(function(response) {
  console.log("Yay! Phaxio assigned id " + response.faxId);
});

Middlware for Callbacks

To confirm delivery, Phaxio can post a callback to you. To use this:

1. Set a callback URL, which must be absolute:

    var phaxio = new PhaxioAPI({ api_key: '...', api_secret: '...' , callback_url: 'https://example.com/fax_callback'});
   

2. Install the middleware in an Express application. Make sure it's not behind any authentication middleware.

    app.use(phaxio.middleware());
   

3. Listen for sent events:

    phaxio.on('sent', function(result) {
      if (result.success) {
        console.log("Fax number " + result.fax.id + " was sent successfully.");
      }
    });
