Front‑end activation:
The module must be enabled in order for the payment methods to appear on the checkout page.

Payment Method Configuration

The payment configuration tab allows you to set up multiple features.

Payment Methods Organization

This setting determines how the payment options are displayed on the checkout page.

Two options are available:

• Choose the payment method on the BNP Paribas page

The customer is redirected to a payment form hosted by BNP Paribas, where they will see all payment methods available on your merchant account.

• Choice of payment methods on the merchant’s website

Display mode

Redirection mode : redirects the customer to the secure payment form hosted by Axepta BNP Paribas.

Iframe mode: integrates the checkout page directly into your site.

Capture mode

This option allows you to choose the payment capture method :

Activation of Automatic Capture

Automatic (J): The capture will be performed automatically at midnight.

Activation of manual capture

Manual capture is performed manually by the merchant through a back‑office configuration.

How to capture a transaction manually

1. Go to “Customize” > “Axepta BNP Paribas” > “Transaction.”
2. You will see the list of processed transactions.
3. When you hover over a line that corresponds to a transaction that has not yet been captured, a “Capture” icon will appear in the Action column.

      4. Cliquez sur ce bouton pour effectuer la capture du paiement.

Une fois la capture effectuée, le statut de la transaction sera mis à jour pour refléter l’action.

Manual capture notifications

Notifications are displayed when attempting a manual payment capture, keeping you informed about the status of the operation.

• Capture successful: A notification informs you that the capture was completed successfully.
• Capture already performed: If the transaction has already been captured, an alert indicates that the capture cannot be re‑executed.
• Capture failed: In case of a capture failure, a detailed notification explains the reason for the problem and guides you on the next steps.

These notifications allow you to precisely track the status of each transaction and act accordingly.

3DS exemption

Corresponds to the configuration of 3DS (the payment authentication method) and its exemption based on the total amount of the customer’s cart.

One-click activation

Activating this feature allows logged‑in customers to save their card for future payments.

To do so, the customer must first tick the option to store their card on the payment page.

Payment Methods

 You can enable or disable the subscribed payment methods in the "Payment methods" tab.

Customization

Allows configuration of the fields sent in the payment form during the redirection.

 Creation of subscription product

installation du cron sur Prestashop

In order to automate the execution of certain tasks (such as triggering subscription payments), you need to configure a scheduled task (cron) on your server.

• 1) Access the cron configuration

On a Linux server, open the terminal and run the following command:

crontab -e

This command allows you to edit the list of scheduled tasks for the current user.

• 2) Add a cron task 

Add the following line to the file:

* * * * * php [PRESTASHOP_MODULE_PATH]/axepta2/run.php action=triggerSubscriptionPayment

• 3) Define periodicity

The five asterisks (* * * * *) define the execution frequency:

* * * * * → every minute

You can adjust this frequency to suit your needs (for example, hourly, daily, etc.).

To help you generate an appropriate cron expression, you can use the following online tool: https://crontab.guru/

Creation of subscription product page 

In Prestashop > "Catalog" > "Products", open the product to be sold as a subscription (or create a new one).
