- Server to server callbacks are initiated from PhonePe server to the url provided by merchant when payment reaches to any terminal state (SUCESS or FAIL)
- To enable server to server callbacks you need to register your static callback url with PhonePe. This is a one time process. The URL should be HTTPS and running on the secured port 443.
Payload
The payload that is going to be sent to the merchant on the specified callback url will have a base64 encoded json.
Upon base64 decoding the response, you should get a json with format similar to the response returned by transaction status API.
This is the best case callback that would be sent from PhonePe server to the merchants’ server. In the event of a callback failure, the onus is on the merchants to use the transaction status API and take the transaction to closure.
Callback headers
Following are the response headers sent with a callback.

- Success/Failure of transaction should be dependent on the code in response parameters
- Cross-check the amount which has been passed in forward payment path(Accept payment API) and in the response of Server to Server callback.
