Telstra Messaging

The SDK for the Telstra messaging API which enables you to send and receive SMS for Australian mobile numbers. For more information about this product, please see here: https://dev.telstra.com/content/messaging-api.

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

Installing

pip install tls.messaging

Getting Started

Set the TLS_CLIENT_KEY and TLS_CLIENT_SECRET environment variables. These are the Client key and Client secret you can find here: https://dev.telstra.com/user/me/apps.

To send your first SMS:

from tls.messaging import sms

sms.send(to="+61412345678", body="Hi")

To set the required environment variables if your application is in app.py:

TLS_CLIENT_KEY="<client key>" TLS_CLIENT_SECRET="<client secret>" python app.py

Authentication

On top of the authentication through the TLS_CLIENT_KEY and TLS_CLIENT_SECRET environment variables, authentication through code is also supported. For example:

from tls.messaging.utils.config import CONFIG

CONFIG.tls_client_key = '<client key>'
CONFIG.tls_client_secret = '<client secret>'

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