The Bharat Billpay on January 31, 2024, issued a notification related to Advisory on Active-Active Health Check API.
BBPOUs are facilitated with two endpoints to send BBPCU transactions across both sites in a round-robin fashion. To ensure high availability, BBPOUs should use the Health Check (HC) API at a regular frequency of 5 seconds while sending the transactions to BBPCU for processing in parallel. When the site health API returns a response other than ‘OK’, the particular site shall be considered down and subsequent transactions shall be routed to the active site(s) till the subsequent health check of that particular site returns a response as ‘OK’.
The BBPOUs are advised to integrate the API as part of the BBPOU’s application to connect to all the sites of BBPCU to achieve zero downtime. The API specification of the functionality has been enclosed with this circular.
The requisite developments are required to be implemented by the BBPOUs within the stipulated time of February 15, 2024.
