This API is used to refund to the customer where the payment transaction is missing in the system. E.g. For payment made through Cash-On-Delivery, the forward payment is made through cash and not on PhonePe. The merchant can initiate a refund through Deferred Credit.

Deferred credit is a two-step process.
First, the merchant initiates the call to /credit/deferred for credit request.
Second, to fulfill the deferred request, the merchant calls Credit Deferred Fulfil
