Connect Deuna from Marketplace to enable the provider in your workspace and make the payment node available in Brain Studio.

​
Before you begin

Make sure you have:
  • An active Deuna enterprise account with the onboarding process completed
  • The Punto de Venta delivered by the Deuna commercial team
  • The Api Key for the environment you are connecting (DEV or PROD)
  • The Api Secret for the environment you are connecting (DEV or PROD)
  • The IVA value — integer percentage (e.g. 15)
  • The Moneda — must be USD
The Punto de Venta, Api Key and Api Secret are only available after completing the Enterprise onboarding with Deuna. If you don’t have them yet, follow the Getting credentials guide first.
