Use the test checkout to validate the full flow before activating your custom gateway in production.
When your gateway has credentials connected (the wizard’s Connect step), Payments → Integrations shows a Test action. It opens the test checkout panel so you can validate the full cycle before production.
Enter order and customer data: name, phone, reference id, amounts, tax, and currency. Optional fields only appear if your body template or headers use them.

Review the preview
The panel shows live how the request looks with placeholders already replaced, before anything is sent to the PSP.
3
Generate the test payment
On confirm, Jelou calls your gateway and shows the resulting paylink with the PSP response, or an error message if it’s rejected.
The test panel includes a return URL field. It does not include cancellation or channel/user identifiers.
Run this flow against the PSP’s sandbox or test mode before going to production or using the gateway in a live Brain flow.
If your PSP redirects after payment, the transaction id parameter matches what it adds to the URL. If you use a status check, the Success / Failed / None mapping is complete.
7
Webhook (if applicable)
Signature header configured if the PSP signs webhooks, correct payload paths, and every relevant event mapped to Success, Failed, or None.
8
Shared webhook secret
The generated or rotated secret is also configured in the PSP’s dashboard.
9
Full test checkout
You generated a real sandbox paylink, completed a payment end to end, and the resulting status is the expected one.
10
Production
Production credentials can create a real charge. Use the PSP’s test mode when it exists. If it doesn’t, run only an authorized minimum-amount transaction and define its void or refund before continuing.
Switch to Production, repeat the test checkout with production credentials, and re-verify webhook signature validation end to end.
A newly created gateway doesn’t appear immediately in the Payment node selector. Jelou verifies the configuration in the background and marks it active when ready. You can’t force that step from the UI.
Plan some time between finishing the wizard and being able to use the gateway inside a Brain flow.
