The Response Queue Service (RQS) provides near real-time access to response events from Mapp Engage through asynchronous API calls. Use it to retrieve email, SMS, and Mobile Push response data, such as bounces, clicks, opens, and unsubscribes, for processing in external CRM, analytics, or dashboard systems.
Compared to a Raw Data Export, response events are available shortly after they occur in Engage.
Typical use cases include polling inbound SMS keywords such as STOP or UNSUBSCRIBE for opt-out processing.
For endpoint details, request and response formats, see the Async API reference.
