# Connect in Brain Studio

> Connect your Mercado Pago account from Marketplace using your Access Token.

Connect Mercado Pago 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 Mercado Pago merchant account](/guides/integraciones/pagos/proveedores/mercado-pago/obtener-credenciales#no-tienes-cuenta-en-mercado-pago)**
* An **Access Token** (Test or Production)

<Tip>
  If you don't have your Access Token yet, follow the
  [Obtaining credentials](/guides/integraciones/pagos/proveedores/mercado-pago/obtener-credenciales) guide.
</Tip>

## Connect from Marketplace

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

    You can find Mercado Pago under the
    **Payments & Processing** category or by using the search bar.

    </Frame>
  </Step>

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

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

    In some UI versions the button may appear as **Install**.
    Both serve the same purpose: initiating the provider connection.
  </Step>

  <Step title="Enter your Access Token">
    A modal will open asking for your **Access Token**.

    </Frame>

    Paste your Access Token (Test or Production) and confirm the connection.
  </Step>

  <Step title="Integration ready to use">
    Brain Studio will validate the token and connect the provider to your workspace.

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

## Using a Test vs Production token

You can connect the integration with:

* **Test Access Token:** for test or QA environments.
* **Production Access Token:** to process real payments.

<Warning>
  Test tokens do not process real payments.
  Make sure to use Production credentials before going live.
</Warning>

***

## Changing the Access Token

If you need to move from **Test to Production** (or rotate credentials):

<Steps>
  <Step title="Disconnect the integration">
    Remove or disconnect Mercado Pago from Marketplace.
  </Step>

  <Step title="Reconnect">
    Repeat the connection process and enter the new Access Token.
  </Step>
</Steps>

Once reconnected, the integration will use the new credentials.

***

## Next step

Once the integration is connected, continue with:
