It is mandatory for the merchant to check the status of a transaction post callback from Accept Payments or Refund workflows.

Once customer is redirected back to merchant website, it is recommended to make a transaction status check with PhonePe backend systems to know the actual status of the payment and, then accordingly process the result.
The payment status can be Success, Failed or Pending. When Pending, merchants should retry until the status changes to Success or Failed.
