Request URL
https://gateway.pay247.io/gateway/payin/update
Request Method
POSTtimestamp must be an integer; examples use milliseconds. Use v3.0 for version. Calculate sign as described in Signature. All merchant requests to the gateway must include uuid and include it in the signature. The response uuid comes from the request header or the server and need not match the request body.
This saves transaction_id and triggers a channel update. The returned status does not imply payment succeeded.
