Once the integration is connected in Marketplace with the Punto de Venta, Api Key, Api Secret, IVA and Moneda, the Deuna node is available in your workspace to use within your flows in Canvas. The node processes the payment through Deuna and exposes the final transaction status so your flow can continue based on the result.

In the left sidebar of Brain Studio, open the Marketplace folder.If the integration is correctly connected, you will see Deuna listed as an available provider.

Important considerations

The environment configured in the node (DEV or PROD) must match the credentials used when connecting Deuna.If they do not match, the payment will not be processed correctly.
In payments with Deuna, the user completes the transaction in the provider’s wallet.In some cases, the payment may momentarily remain in a pending state. In that case:
  • the user receives a notification in the conversation
  • the flow waits for the confirmation
When Deuna confirms the final result, the flow continues automatically through:
  • Pago Exitoso
  • Pago Fallido
The pending state is not exposed as an independent node output.
