error 999

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:

One of the fields of your form contains data that strongly resembles a credit card number.

For security reasons, the gateway cannot store non-encrypted credit card numbers.

Additionally, if the gateway detects a field that resembles a credit card number in the payment form, the payment request is automatically rejected.

The field that resembles a credit card number is present in the e-mail that you will receive. This field contains XXXXXX.

In the example on this page, this field is vads_order_id, but it can also be another field.

One of the fields of your form contains the production or test key.

For security reasons, the gateway detects if the production or test key is present in the payment form.

In this case, the payment request is automatically rejected.
