Query Status With A1Pay Reference
The second way you can query for the status of a transaction, this time, using the A1Pay reference that is returned to your ReturnURL through URL query parameters
get
https://a1pay.net/api
/query/status
Get Transaction Status
Always look out for the IsSuccessful property of the data object in the response. A status=success alone is not enough to determine that your transaction is successful
Its always a good practice to log all responses from A1Pay for future reference.
