Reply To: Problem with payment gateway

If I would know a solution I would tell you for sure.

I’ve tried around with the code and am sure the problem is not on easyreservations side. Everything works as the ogone documentation states.

Try to make the SHA-IN and SHA-OUT to be different.
The “unknown order/1/s” problem is often related to encoding mismatches. Ogone is default ISO, but Magento is UTF-8. Switch Ogone technical settings to UTF-8 to solve the issue.
