Messaging API

Integrate messaging into your digital platforms

Get the power to communicate with engaging SMS messaging in your web and mobile apps in near real-time and at scale.

Telstra’s Messaging API is a simple, secure and reliable REST API that simply integrates SMS messaging across your existing marketing suite.

Key features

Inform and educate your audiences as a group or as individuals, promptly notify and update employees of changes like roster updates, boost security by enabling two factor authentication, or provide SMS alerts for utility outages or delivery statuses to improve customer and employee experience. Our Messaging API is perfectly suited for a range of messaging applications.

Reliable delivery

Connect directly across our leading Telstra mobile network, providing a direct carrier connection for more reliable performance.

If you have a pay-as-you-go or enterprise plan, you can resolve issues quickly with local support from our dedicated expert team.


Reliable performance

Feel confident you can deploy the Messaging API into your environment and get to work straight away as our code is rigorously tested and pre-prepared for your use.

A messaging solution that works for your audiences

Choose how your Messaging API works best for your customers, whether that’s engaging in two-way communication, broadcasting to large groups or interaction with individuals.

The support of a dedicated team

Every user is supported by our comprehensive online resources, while paying customers have around-the-clock access to a dedicated support team to resolve issues as they arise.

How it works?

Simplify and secure your account management

Deliver an additional level of security and confidence for your core applications and services and be sure the highest security standards are always met with two-factor authentication delivered by messaging.

Improve customer and employee experience

Timely communication can be critical to both customers and employees. Send SMS notifications and alerts for utility outages or delivery updates, while prompt schedule notifications for field teams helps them stay on track during the day or stay safe in remote locations.

Communicate at speed

For organisations managing complex processes or large groups of people, responding to status changes can be critical. When production lines need attention or an employee roster changes, prompt notifications can help ensure no one misses a beat – or a shift.
