Release Notes

Version Notes
3.0.0 Dropped support for node versions less than 6
3.0.2 Updated the URL used for Bandwidth's V2 Messaging

Client initialization

All interaction with the API is done through a client Object. The client constructor takes an Object containing configuration options. The following options are supported:

Field name Description Default value Required
userId Your Bandwidth user ID undefined Yes
apiToken Your API token undefined Yes
apiSecret Your API secret undefined Yes
baseUrl The Bandwidth API URL https://api.catapult.inetwork.com No

To initialize the client object, provide your API credentials which can be found on your account page in the portal.

var Bandwidth = require("node-bandwidth");
var client = new Bandwidth({
    userId    : "YOUR_USER_ID", // <-- note, this is not the same as the username you used to login to the portal
    apiToken  : "YOUR_API_TOKEN",
    apiSecret : "YOUR_API_SECRET"

Your client object is now ready to use the API.

Callbacks or Promises

All functions of the client object take an optional Node.js style (err, result) callback, and also return a Promise. That way if you want to use Promises in your application, you don't have to wrap the SDK with a Promise library. You can simply do things like this:

Promise style

    from : "+12345678901", // This must be a Catapult number on your account
    to   : "+12345678902",
    text : "Hello world."
.then(function(message) {
    console.log("Message sent with ID " + message.id);
.catch(function(err) {

If you're not into that kind of thing you can also do things the "old fashioned" callback way:

Callback style

    from : "+12345678901", // This must be a Catapult number on your account
    to   : "+12345678902",
    text : "Hello world."
}, function(err, message) {
    if (err) {
    console.log("Message sent with ID " + message.id);

Using Messaging V2 API

Both callback and promise styles are supported

// First you should create and application on Bandwidth Dashboard
var dashboardAuth = {
    accountId    : "accountId",
    userName     : "userName",
    password     : "password",
    subaccountId : "subaccountId"
client.v2.Message.createMessagingApplication(dashboardAuth, {
    name: "My Messaging App",
    callbackUrl: "http://my-callback",
    locationName: "My Location",
    smsOptions: {
        enabled: true,
        tollFreeEnabled: true
    mmsOptions: {
        enabled: true
}).then(function (application) {
    // application.applicationId contains id of created dashboard application
    // application.locationId contains id of location
    // Now you should reserve 1 ore more numbers on  Bandwidth Dashboard
    return client.v2.Message.searchAndOrderNumbers(dashboardAuth, application, new client.AreaCodeSearchAndOrderNumbersQuery({areaCode: "910", quantity: 1}))
        .then(function (numbers) {
            // Now you can send messages using these numbers
            return client.v2.Message.send({from: numbers[0], to: ["+12345678901", "+12345678902"], text: "Hello", applicationId: application.applicationId});
