# Connect in Brain Studio

> Connect your Deuna account from Marketplace using your Punto de Venta, Api Key, Api Secret, IVA and Moneda.

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`

<Warning>
  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](/en/guides/integraciones/pagos/proveedores/deuna/obtener-credenciales) guide first.
</Warning>

## Connect from Marketplace

<Steps>
  <Step title="Open Marketplace">
    In Brain Studio, go to **Marketplace** from the side menu.

    You can find Deuna in the **Payments & Processing** category or using the search bar.
  </Step>

  <Step title="Select Deuna">
    Click on the **Deuna** card to open its detail.
  </Step>

  <Step title="Click Connect or Install">
    Click **Connect**.
  </Step>

  <Step title="Complete the installation modal">
    A modal will open requesting these fields:

    * **Punto de Venta** — point of sale identifier delivered by Deuna during onboarding
    * **Api Key** — access key for the selected environment (DEV or PROD)
    * **Api Secret** — secret key for the selected environment (DEV or PROD)
    * **IVA** — applicable tax percentage in Ecuador (e.g. `15`)
    * **Moneda** — must be set to **USD** for this integration

    Enter all five values and confirm the installation.

    </Frame>
  </Step>

  <Step title="Validate the connection">
    Brain Studio will validate the configuration and connect the provider to your workspace.

    <Check>
      If Deuna appears as connected in Marketplace and the node is available in the Canvas, the integration was enabled correctly.
    </Check>
  </Step>
</Steps>

## Installation from Jelou Agent

If you install Deuna from **Jelou Agent**, you will see the same installation modal and must enter exactly the same information:

* **Punto de Venta**
* **Api Key**
* **Api Secret**
* **IVA**
* **Moneda (USD)**

<Info>
  The installation from Marketplace and the installation from Jelou Agent use the same provider configuration.
</Info>

***

## Test and production mode

Deuna uses **different credentials** for the development and production environments. When connecting in Brain Studio, the Api Key and Api Secret you enter determine which environment the integration will operate in.

* For **testing:** use the development Api Key and Api Secret delivered by Deuna
* For **live payments:** use the production Api Key and Api Secret delivered by Deuna

***

## Next step

Once the integration is connected, continue with:
