About Cofidis

General information about Cofidis

The 4-star card was launched by Cofidis as soon as it was created in 1982, initially exclusively for customers of the 3 Suisses brand. It is a private card that combines payment facilities and loyalty benefits. The design of tailor-made products and services, adapted to customers' expectations and needs, has enabled Cofidis, over the years, to extend the 4-star card to other brands (in stores and on the Internet) such as Feu Vert, Maty, Blancheporte, Helline, Bon prix, etc.

From now on, we are talking about the 4-star network. Pay for your purchases in several instalments.

The 4-star card is a revolving credit card that offers you the possibility, depending on the amount of your purchases and the brand, to pay in several instalments.

Parameters for credit card payments with Cofidis via Paygate form


Note regarding Cofidis parameter Addata1: Cofidis expects all reservations to be made with the transaction code 590 and replaced by the correct transaction code during the capture. Since the invoice number and date may not yet be known at the time of the reservation, transfer spaces in their place during the reservation. If the transaction code is no longer available when invoicing, the reservation can already be carried out with the correct code. Computop then replaces the capture transaction code by 590 and changes it back when invoicing to the one transferred during the reservation. The invoice number and date are adopted at the same time and transferred to Cofidis.

To carry out a reversal with a reference transaction, please use the following URL:


Notice: For security reasons, Paygate rejects all payment requests with formatting errors. Therefore, please use the correct data type for each parameter.

Notice: Reverse.aspx does not only reverse authorisations, but any LAST TRANSACTION STAGE!! If the last transaction was a capture, Reverse.aspx initiates the reverse, e.g. a credit. Therefore, the utmost caution is urged. Use is at your own risk. We recommend checking the transaction status with Inquire.aspx before using Reverse.aspx.

If the transaction is submitted again with the same ReqID, Paygate will not carry out the payment, but will just return the status of the original transaction.

Response parameters for reversals of credit card payments with Cofidis via socket connections



Batch processing via the interface

Basic information about using Batch files and about their structure can be found in the Batch Manager manual. Within batch processing not alle functions are available which are usually available for the online interface.

This section describes the parameters which must be transferred within the data set (Record) for executing payments / credits with Cofidis and which information can be found within the response file about the payment status.

For Batch calls there must be considered batch versions, from which optional parameters depend. All version designations starting with „2.“ pertain calls for a group of enterprises. That means within a batch file for a particular MerchantID can be transferred transactions for other merchants with a separate Sub-MID.

Following table gives an overview of all batch versions that are possible for a specific action and their specialities:
