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 specified amount is higher than the maximum supported amount|
You have forced the payment method to be used (vads_payment_cards) in your payment form.
However, the transmitted amount is higher than the maximum amount supported by this payment method.
