Africa's Talking Node.js SDK

The wrapper provides convenient access to the Africa's Talking API from applications written for Node.js.

Documentation

Take a look at the API docs here.

Install

You can install the package from npm by running:

$ npm install --save africastalking

Usage

The package needs to be configured with your app username and API key, which you can get from the dashboard.

You can use this SDK for either production or sandbox apps. For sandbox, the app username is ALWAYS sandbox

const credentials = {
    apiKey: 'YOUR_API_KEY',         // use your sandbox app API key for development in the test environment
    username: 'YOUR_USERNAME',      // use 'sandbox' for development in the test environment
};
const Africastalking = require('africastalking')(credentials);

// Initialize a service e.g. SMS
const sms = Africastalking.SMS

// Use the service
const options = {
    to: ['+254711XXXYYY', '+254733YYYZZZ'],
    message: "I'm a lumberjack and its ok, I work all night and sleep all day"
}

// Send message and capture the response or error
sms.send(options)
    .then( response => {
        console.log(response);
    })
    .catch( error => {
        console.log(error);
    });

See example for more usage examples.
