Understanding CACF payments with Worldline Sips

General principles

The CACF is a private mean of payment offered by major retailers, with the exclusive acquirer Crédit Agricole.

The CACF card, offered by the Crédit Agricole Consumer Finance Group, is a "co-branded" card that can be used:

  • Like an ordinary bank card under the Visa means of payment.
  • Like a CACF private credit card allowing to make a payment on credit.

By these means of payment, the customer can choose the suitable credit terms from the means of payment list of choice. This mean of payment specifies the desired credit conditions; in particular: the credit rate, the number of payment due dates, the amount of each maturity, the additional costs related to the payment.

Payment pages

All pages developed respect the principles of responsive design and can be used on all terminals, smartphones/tablets and others.

The payment customisation rules in effect on Worldline Sips are applied on the pages of this payment process.

The customer who clicks on the "VISA CACF" card logo is redirected from Worldline Sips to the Crédit Agricole Consumer Finance payment options page of choice.

This page allows, among other things, the choice of a dual offer type option, with the number of monthly payments or the amount of the monthly payments entry by the customer. The cardholder can view the credit conditions on this page displayed by CACF.

The customer is then redirected by Crédit Agricole Consumer Finance to Worldline Sips. Crédit Agricole Consumer Finance sends Worldline Sips the payment option applicable to the purchase during this redirection.

The wording of the payment option sent to Worldline Sips will be displayed on the Worldline Sips pages following the payment process.


the Crédit Agricole Consumer Finance payment options page of choice

The customer is then redirected to the required information entry page.

They enter the following information on this page:

  • card number
  • card expiry date
  • card security code

If any of these data are missing or invalid, or if the card number entered is not in range, an error message is displayed and a new entry is requested.

The standard operation of Worldline Sips applies: the number of input attempts is capped, the code 75 is returned if the number of attempts is exceeded.


the card information entry page

Note: in case of the payment process breaking, the manual and automatic responses are not sent directly. Every hour, Worldline Sips collects the transactions in this case and sends an automatic response with all the data of the transaction.

Signing your CACF acceptance contract

In order to offer the CACF means of payment on your website, you have to sign an acceptance contract with Crédit Agricole Consumer Finance and hold a CB distance selling contract supporting the 3-D Secure. Thereafter, you transmit us the contract number for recording in our information system.

Making a CACF payment

You can offer the CACF mean of payment through the Sips Paypage which directly acts as the payment interface with customers via their web browser.

The remittance modes available for a CACF transaction are:

  • Cancellation mode: default mode allowing transaction remittance on a predefined date, called capture delay. When this capture delay is reached, the remittance is sent automatically. This delay is set via the captureDay field with its 0 default value (end-of-day payment).
  • Validation mode: you must validate the transaction to trigger the remittance. A capture delay must also be defined. When this capture delay is reached or exceeded, you will not be able to validate the transaction, which will therefore expire automatically.

The diagram below explains the different transaction statuses according to the chosen capture mode:


diagram showing the different statuses of a transaction

If the merchant chooses validation mode, the transaction will either go to the To validate status if it has been accepted (response code 00) or to the refused status if it has been refused (response code different of 00). If the merchant chooses the cancellation mode, the transaction will either go to the To capture status if it was accepted (response code 00) or to the refused status if it was refused (response code different of 00).
