The Official SDK for the Telstra messaging API.

⚠️ This SDK is experimental, everything is subject to change

npm i -s @telstra/messaging

You can find the Client key and Client secret here: https://dev.telstra.com/user/me/apps.

Before sending and receiving messages you will need to get your dedicated Australian number, see Subscription section below.

For free trial accounts, you will need to setup a list of registered destinations first, see Free Trial section below.

/** Using CommonJS */
var { Message } = require('@telstra/messaging');

const message = new Message();
message
    .send({
        to: '<MOBILE_NUMBER>',
        body: 'Hello from Messaging SDK',
    })
    .then(results => {
        console.log(results);
    })
    .catch(error => {
        console.error(error);
    });

⚠️ To load an ES module, set "type": "module" in your package.json or use the .mjs extension.

/** Using ES Modules (ECMAScript) */
import { Message } from '@telstra/messaging';

const message = new Message();
message
    .send({
        to: '<MOBILE_NUMBER>',
        body: 'Hello from Messaging SDK',
    })
    .then(results => {
        console.log(results);
    })
    .catch(error => {
        console.error(error);
    });

Authentication through environment variables, a shared credentials file and json file import are supported.

Export the following two environment variables, replacing the values with your own credentials.

export TELSTRA_CLIENT_ID="<CLIENT_ID>"
export TELSTRA_CLIENT_SECRET="<CLIENT_SECRET>"

Create a ~/.telstra/credentials file in your home path with the following contents, replacing the values with your own credentials.

[default]
TELSTRA_CLIENT_ID = <CLIENT_ID>
TELSTRA_CLIENT_SECRET = <CLIENT_SECRET>

Create a json file in your project path with the following contents, replacing the values with your own credentials.

{
    "TELSTRA_CLIENT_ID": "<CLIENT_ID>",
    "TELSTRA_CLIENT_SECRET": "<CLIENT_SECRET>"
}

Then import the json file into your project source.

import { Message } from '../dist/index.js';
import AUTH_CONFIG from './credentials.json';

const message = new Message(AUTH_CONFIG);

This should be done before any interactions requiring authentication, such as sending a SMS.

Telstra offers a free trial for the messaging API to help you evaluate whether it meets your needs. There are some restrictions that apply compared to the full API, including a maximum number of SMS that can be sent and requiring the registration of a limited number of destinations before SMS can be sent to that destination.
