Webhook

The webhook URL is automatically configured per order:

https://your-shop.com/module/nopaynpayment/webhook

Manual Capture

When enabled for credit card payments:

• Payment is authorized but not captured at checkout
• Capture occurs when the order is shipped / marked as completed
• If the order is cancelled, the authorization is automatically voided

Auto-Refund

If a captured payment order is cancelled, the module automatically issues a full refund. Partial refunds can be processed via PrestaShop credit slips.

Checkout Button Labels

For the best user experience with offsite redirect flows, consider updating the checkout button label to "Review order" instead of "Confirm and pay", since the actual payment happens on the Cost+ hosted page. This is a global PrestaShop setting, not module-specific.

Webhook

The webhook is automatically configured by the module. No manual setup is required.

Webhook

The webhook is automatically configured by the module. No manual setup is required.

Webhook

The module configuration page shows a webhook URL. Copy it into your Cost+ dashboard if your Cost+ account requires a static webhook registration.

The webhook endpoint receives Cost+ events, then calls Cost+ again with GET /orders/{id} before updating the PrestaShop order — this keeps return-URL and webhook handling idempotent.

Expiry Cron

The module configuration page shows an expiry-cron URL. Schedule it to run every minute:

* * * * * curl -fsS "https://your-shop.example/index.php?fc=module&module=costpluspayment&controller=cron&token=..." >/dev/null

Use the exact URL shown in your PrestaShop back office — the token is generated during installation and is different for every shop. The cron endpoint cancels stale pending Cost+ orders after the configured Checkout Expiry.

Manual Capture & Refunds

• With Manual Capture enabled, payments are authorized at checkout and captured when the order is shipped / marked as completed
• If a captured order is cancelled, the module issues a full refund automatically
• Partial refunds are processed through PrestaShop credit slips
