Check Status API

S2S and Check Status API Handling

Once the customer is redirected back to the merchant website/app, merchants should check with their server if they have received the Server-to-Server Callback response. If not, it is mandatory to make a Transaction Status API 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.

📘
Check Status API - Reconciliation [MANDATORY]
If the payment status is Pending, then Check Status API should be called in the following interval:
The first status check at 20-25 seconds post transaction start, then
Every 3 seconds once for the next 30 seconds,
Every 6 seconds once for the next 60 seconds,
Every 10 seconds for the next 60 seconds,
Every 30 seconds for the next 60 seconds, and then
Every 1 min until timeout (15 mins).
