Notification System API | Gmail and Twilio Implementation Template

(0 reviews)


Underlying all IT architectures are core systems of records that are often not readily available due to its complexity and connectivity concerns. System APIs provide a means of hiding that complexity from the user while exposing data and providing downstream insulation from any interface changes or rationalization of those systems. This API provides an implementation best practice for a notification service that integrates with multiple systems like Gmail and Twilio and exposes a RESTful interface that triggers a notification.

Accelerator Implementations

This API is one of many components included in the Accelerator for Salesforce Commerce Cloud, the Accelerator for Banking, and the Accelerator for Retail.
