When do you need this?

You will need this when you try to Connect Mercado Pago in Marketplace and Brain Studio asks you for an Access Token.
To connect Mercado Pago with Brain Studio you need an Access Token, associated with an application (App) created in the merchant’s account. This guide explains how to obtain test credentials and production credentials, and when to use each one.
By the end of this guide you will have an Access Token (Test or Production) ready to install Mercado Pago in Brain Studio.

​
Before you begin

You need an active account in Mercado Pago, access to the merchant panel, and permissions to create applications. No advanced technical knowledge is required.

Steps to obtain credentials

1

Log in to the Mercado Pago panel

Sign in to the Mercado Pago merchant account.
2

Access your integrations

From your account menu, navigate to:Your business → Settings → Your integrationsThis is where applications and credentials for the account are managed.
Navigating to Your integrations in the Mercado Pago panel
3

Create an application

To generate credentials, you must first create an application:
  1. Click Create application
  2. Enter a name for the app (the name is free-form)
  3. Complete the creation
The application does not process payments on its own. It is used solely to generate credentials.
4

Access the App credentials

Inside the created application:
  1. Go to the Credentials section
  2. You will see two types of credentials:
    • Test credentials
    • Production credentials
If you can see the Access Token in the Credentials section, this step was completed successfully.
5

Copy the Access Token

  • Generated automatically when the application is created.
  • Include a test Access Token.
  • Allow you to test the integration without processing real payments.
  • Ideal for development and internal validations.
Copy the test Access Token to use in test environments.
For production environments in Jelou, you must use production credentials. Test tokens do not process real payments.
6

Use the Access Token in Brain Studio

During installation from the Brain Studio Marketplace you will be asked to enter the Access Token.Once configured:
  • Payments are processed directly in the merchant’s account.
  • Jelou does not hold funds.
  • The payment result returns to the conversational flow.

​
Troubleshooting

Mercado Pago may require:
  • Completing business tax information
  • Defining industry or category
  • Adding a valid website
Review the Business data section in your Mercado Pago account and complete any pending information.
Verify that:
  • The application was created correctly
  • You are inside the App and not in the general view
  • You have sufficient permissions on the account
If the issue persists, review the user permissions in Mercado Pago.

​
Best practices

  • Do not share your Access Token.
  • If you suspect exposure of the token, rotate it from the Mercado Pago panel.
  • Use test tokens only in test environments.
  • Switch to production credentials before going live.
