I'm getting the following error when trying to build a SagePay Form integration.
3087 : The SuccessURL format is invalid.
The url being sent is in the following format http://sub.domain.co.uk/folder/
The documentation for the field says..
This should be the fully qualified URL (including http:// or https:// header). It is the URL of the page/script to which the user is redirected if the transaction is successful. You may attach parameters if you wish. Sage Pay Form will also send an encrypted field containing important information appended to this URL (see below).
As far as I can tell the SuccessUrl I am sending is perfectly valid & fully qualified. Am I missing something simple?
$mySage->addFieldToCrypt("SuccessURL", 'http://sub.domain.co.uk/folder/');
