INVALID with SagePay
Hi,
I have integrated with SagePay using their Form method (not server), and the transaction is passing right through their simulator with no problems at all. However, I am getting an INVALID status code even though the transaction is fully stored on SagePay's server with no problem.
The debugging code outputs the following:
SUCCESS:
STATUS CODE: INVALID
ERROR MSG:
Why is this coming back as INVALID if the transaction was successful?
Thanks,
Chris.
