error 48

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:

The format of the field is incorrect.

The vads_return_mode field allows to specify the data transmission method used while returning to the merchant website. Its format must be enum.

The possible values are:
Value Description
absent, empty or NONE No parameters will be transmitted to the Return URL.
GET The return fields will be transmitted to the return URL in an HTTP GET form (in the “query string”).
POST

The return fields will be transmitted to the return URL in an HTTP POST form.

If the return to the shop in done from an environment other than https, a security pop-up message will be displayed to the buyer.

Check that the value entered in the form is correct.
