In PRODUCTION mode, if your buyer gets an error message such as:
|An error occurred during the payment request, please make sure that the posted parameters match the ones specified in the documentation.|
It becomes impossible to make the payment and the transaction is definitively lost.
You will receive an email notification containing the form that the gateway was unable to process and the value of the invalid field.
We invite you to check the following reason(s) to resolve the issue:
|The value of the field does not respect the URL format.|
The vads_shop_url field is used to transmit the shop URL that appears on the payment page and in payment confirmation e-mails. It must consist of alphanumeric and special characters (except “<” and “>”) with a variable length up to 1024 characters (ans..1024).
Make sure the field respects the format of a URL.
