error 10101

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 e-mail 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:

No MIDs associated with your shop can be used

Your shop is associated with several MIDs, but none of them correspond to the criteria specified in the payment form.

The error page states the reason for which every MID has been invalidated for this payment request.

There can be many possible reasons, including:

  • the MID is closed
  • the payment restrictions are not respected (minimum/maximum amount)
  • the Merchant ID does not support the TEST mode
  • the Merchant ID does not support e-commerce payments
  • ...

You can update your payment form to reduce the number of returned errors.
