  1. Login or Register to Admin Portal

  2. Select Functions

  3. Select your desired App and Keyset

  4. Select "Explore Templates" and proceed with selected integration.


Once the Infobip SMS Function is installed, the Infobip SMS Handler inside it must be updated with your Infobip credentials. The INFOBIP_API_KEY constant at line 3 should be populated with your Infobip API key. Note that the function should be saved and restarted after this modification.

Infobip SMS Handler looks for several properties in the messages that it processes. Messages should have to, text and from properties, and all of them should be strings. Detailed descriptions for each property can be found at Infobip API documentation.

After making a request to Infobip, SMS Handler will publish API response in infobip-api-response channel. Structure of messages published there corresponds to response model from the API documentation linked above. Name of the response channel can be modified by changing the RESPONSE_CHANNEL constant in the Handler code.

Lastly, SMS Handler can work as both Before Publish or Fire or After Publish or Fire function type. If used as Before Publish it will emit string messages noting if sending was successful or failed. In both cases, full API response details will still be published on infobip-api-response channel.
