error 10191

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.

The FRANFINANCE_MISSING_AUTHENT_CHAIN_FOR_WITH_FEES_OPTION error appears during a transaction via Franfinance.

We invite you to check the following reason(s) to resolve the issue:

Authentication string missing for the "with fees” option.

You have forced fee activation for a Franfinance payment via the vads_acquirer_transient_data field.

However, the corresponding authentication key is missing in the configuration of your Franfinance MID.

To resolve the issue:
  • Enter the missing key in your MID configuration.
  • Update your payment form to use the options supported by your MID.
