Once your custom gateway is created, connected, and active, it becomes available in the Payment node’s selector in Brain Studio.

​
Node configuration

This selector only lists custom gateways connected through Payments. It doesn’t mix catalog providers or other company credentials.

​
Node outputs

The Payment node exposes six outputs you need to wire up in your flow:
The Success / Failed / None mapping you defined when configuring your gateway’s webhook and status check only determines the Payment successful, Payment pending, and Payment failed outputs — that’s why getting it right matters when you create the gateway.
Don’t leave the Payment failed and Timeout branches unhandled — without them, the customer can be left without a response if the charge doesn’t complete.

​
Use cases

A business operating with a regional PSP that isn’t in Jelou’s provider catalog: it defines its checkout endpoint as a custom gateway and maps webhook responses to the Payment node’s outputs, without depending on Jelou building a dedicated integration.
A business whose PSP doesn’t offer reliable webhooks: it enables Check status with the PSP on return when creating the gateway, and the flow uses the Payment pending output while Jelou checks the transaction’s status.
A business already using a catalog provider that needs to add another PSP for a different country or payment method: it sets up the custom gateway in parallel and selects one or the other in the Payment node depending on the flow or customer segment.
