Overview
Using this API, Merchant can initiate a payment from his / her account to a Customer. The request message has details of the Payee VPA in the MerchantBody section. It has other details like Amount, Payer VPA etc.
This API follows an asynchronous processing model. On receiving a PAY request from the Merchant, Federal Bank will validate the request and will send an Acknowledgement to the Merchant. If the request is valid, Federal Bank will then send a transaction response message (RespPay) to the Merchant with details of the payment, transaction status etc. The RespPay response message will have the same TransactionId as the original PAY request message, and the TransactionType will have a value of PAY. Merchant must acknowledge receipt of the RespPay message, which will in turn complete the process flow.
