error 143

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 payment method supports the requested country.

You have specified the payment method (vads_payment_cards) to be used in your payment request and your shop is associated only with a PPRO contract.

The buyer’s country (vads_cust_country) transmitted in your payment form is not supported by any payment methods accepted by your PPRO contract.

To resolve the issue:

  • Update the buyer’s country transmitted in your form.
  • Update MID association via your Expert Back Office (Settings > Shop > MID association menu) by associating an e-commerce MID that accepts the specified currency.

  • Contact the Middle Office.
