Telstra Messaging

The Official SDK for the Telstra messaging API.

:warning: This SDK is experimental, everything is subject to change

Installing

npm i -s @tls/messaging

Getting Started

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

Getting started using CJS (CommonJS)

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

Getting started using ESM (ES Modules)

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

/** Using ES Modules (ECMAScript) */
import { Message } from '@tls/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

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

Environment variables

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

export TELSTRA_MESSAGING_CLIENT_ID="<CLIENT_ID>"
export TELSTRA_MESSAGING_CLIENT_SECRET="<CLIENT_SECRET>"

Shared credentials

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

[default]
TELSTRA_MESSAGING_CLIENT_ID = <CLIENT_ID>
TELSTRA_MESSAGING_CLIENT_SECRET = <CLIENT_SECRET>

JSON file import

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

{
    "TELSTRA_MESSAGING_CLIENT_ID": "<CLIENT_ID>",
    "TELSTRA_MESSAGING_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.

Free Trial

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.
