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:
|Your Merchant ID does not support distance payments|
The verification process performed by the payment gateway, based on the parameters transmitted in your payment form, has resulted in selecting a MID that does not support payments of distance sales type (the vads_payment_src field is set to MOTO in your payment form).
