IMPORTANT UPDATE TO FREE TRIAL MESSAGING API USERS:
Before sending any further trial messages, Free Trial apps will now be required to register destination mobile numbers that will be used while trialling Telstra's Messaging API. Up to five destination numbers can be registered. These are the ‘B’ numbers. Any messages sent to numbers NOT on your app’s registered Bnum list will fail.
You will no longer be able to send messages to more than 5 numbers. This change will take effect 8/8/20.
This is a necessary measure for us to ensure the free trial remains a safe, secure way for our developers to test and validate their business solutions with critical communications.
Instructions for Registering your max 5 ‘B’ numbers using a POST API call will be updated in the API documentation shortly. This can only be done once. You are not able to change the list of registered B numbers after registering them, so we recommend you include your own number to ensure that you can send and receive meaningful test messages while using the free trial. You can check which numbers have been registered using the below GET/bnum call.
We will provide further details in the coming week to reduce the disruption to your current services and provide support in registering yout B numbers, or transitioning to a paid service which does not have these limits.
