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.

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.

  • 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.
