StaticQR Server to Server Callback (v1)

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.
NOTE: When a static QR transaction is being performed by the customer either SUCCESS or FAIL, the callback response is being sent from phonepe server on the mapped callback endpoint/URL within 5 seconds of the transaction. Our servers need an acknowledgement as 200 OK success from your end orelse we consider that 1st attempt as FAILED callback and retry for the 2nd attempt. 3 retries are performed from the server side on the merchant’s callback endpoint/URL

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.

Header Name	Header Value
`Content-Type`	application/json
`X-VERIFY[ Old Version Callback ]`	SHA256(MerchantId+TransactionId+Amount+SaltKey) + ### + salt index ( This XVERIFY will be used for decoded JSON format callback response )
`X-VERIFY[ Default Callback ]`	SHA256(response + salt key) + ### + salt index ( This XVERIFY will be used for encoded callback response )
