# BBPS Biller Integration

This document explains the APIs to be implemented by the billers to integrate with the BBPS system.

Billers need to integrate the following APIs and endpoints. The APIs are asynchronous, meaning once an API is triggered, BBPS BOU servers will expect an Acknowledgement from the server immediately, before receiving the Response after processing. The actual response will be sent from biller systems as a follow on HTTP request .

In this case, whenever the BBPS Protocol system sends a request to the Biller server, the Biller server needs to send the Acknowledgement. Once the request is processed at the biller server, the Biller server will send the Response back to the Protocol server aka Bank server.
