Frequently Asked Questions

Common questions about Relqor — Gateway for Worldline Sips

In Bank, choose the bank named on your contract: the default, Worldline Sips, is for contracts signed directly with Worldline. The secret key and its key version come from your bank's key download extranet. Enter them with your 15-digit merchant ID under Test credentials or Production credentials, to match Mode; the key must not contain spaces. When you generate a new key, update the key version at the same time: according to the Sips documentation, a new key used with the old version is refused (code 34).

Yes. Each bank's Paypage POST guide publishes a public test account (for Mercanet, on its acceptance server). Select that bank in Bank, keep Mode on Test and enter the account under Test credentials. Test cards: Worldline Sips, Sherlock's and Sogenactif: the last two digits of the card number set the result, with any 3- or 4-digit CVV. 4100000000000000 is accepted; 4100000000000005 is refused, and the page may then offer another try (cancelling sends code 17). Mercanet: use its own published test cards, such as 4112948576210600 (accepted). Even in test mode, your store must be reachable from the Internet to receive the automatic response.

New installations start in Test mode, which sends customers to your bank's test server (the acceptance server for Mercanet). Test mode is not limited to administrators: while the Enable box is ticked, any customer can choose this payment method, and a payment accepted by the test server marks the order as paid like a real one. To go live, fill in Production credentials, set Mode to Production and save; if Production credentials are incomplete, the payment method disappears from checkout. A bank response to a payment started in the other mode never changes an order's status.

The payment method appears in the classic checkout and in the checkout block only when: the Enable box is ticked; the store currency is the euro; the credentials for the selected Mode are complete: a 15-digit merchant ID, a key version of 1 to 10 digits and a secret key. Test and production credentials are separate, so check the Test credentials or Production credentials section that matches Mode.

Only by the automatic response that the bank's server sends to your store. It does not depend on the customer clicking "Continue" on the bank's page, and the customer's return to your store never changes the order. While the order is "Pending payment" or "On hold", the order-received page tells the customer that the payment is being confirmed. If your store cannot be reached from the Internet, orders stay "Pending payment".

No. The plugin sends both addresses with every payment request, built from your WordPress site address: /?wc-api=relqor_sips_notify for the automatic response and /?wc-api=relqor_sips_return for the customer's return. The automatic response address must be reachable from the Internet, without any login.

Open the order: each signed bank response for this order adds a note, usually with the response code and its meaning. For more detail, read the WooCommerce log, source relqor-sips (in English, with the secret key and full seals masked). The main lines are: "redirecting to the … payment page (reference …)": the payment form was shown to the customer, whose browser then submits it to the bank. This line alone does not prove that the customer reached the bank's page. "automatic response accepted (valid seal, IP …) → …": a signed bank response arrived. After the arrow, complete, on-hold, failed or cancelled means the status changed; any other word means only a note was added. "Invalid or missing seal — automatic response ignored": the request could not be verified with the secret key of the selected Mode (for example a wrong or replaced key, a Mode change, or a request not sent by the bank). The order was not changed. If the bank's page shows "Invalid signature" instead of the payment form, check the secret key and key version of the selected Mode.

The plugin only changes an order's status when the bank's automatic response reaches your site address followed by /?wc-api=relqor_sips_notify. The bank's server sends it as a POST, without any login. If a firewall, bot protection, maintenance mode or password protects the whole site, let this URL through. The plugin does not filter by IP address. If the relqor-sips log shows "Invalid or missing seal — automatic response ignored", responses arrive but cannot be verified with the secret key of the selected Mode: check the key, and whether Mode was changed after the payment started. For each affected order, look up its reference (shown in the log line "redirecting to the … payment page") in your bank's extranet and, if the payment was accepted, change the status yourself. A response that arrives later never undoes a paid status.

The order note says which case applies: "Authorisation accepted, capture awaiting validation in the extranet (mode …)": the payment was authorised, but the capture mode shown is not AUTHOR_CAPTURE or IMMEDIATE. This mode comes from your shop's settings at the bank, not from the plugin; with VALIDATION, the money is only collected after you validate the payment in your bank's extranet. "Fraud warning (ORANGE score)": the bank returned code 05 with an ORANGE fraud score. Accept or refuse the payment in your bank's extranet. "Payment pending": the bank answered with code 60 (Transaction pending) or 62 (Awaiting confirmation). Your server never asks the bank for updates, so once the payment is settled with your bank, change the order status yourself if it has not changed.

The plugin sets these statuses after the bank's automatic response, with an order note ("Payment declined" or "Payment cancelled or abandoned") that gives the response code and its meaning: Failed: the bank refused the payment, for example code 05 (Authorisation refused), 51 (Amount too high) or 54 (Payment method expired). Cancelled: code 17 (Cancelled by the buyer) or 97 (Session expired). According to the Sips documentation, when a customer abandons the payment page, code 97 arrives about 15 minutes after the redirection. This only happens while the order is "Pending payment" and for its latest payment attempt; otherwise only a note is added. A successful payment response that arrives afterwards is still applied.
