Create application

Applications are registered entities within Mercado Pago that act as a unique identifier for managing the authentication and authorization of your integrations. In other words, they serve as the link between your development and Mercado Pago, and they constitute the first stage in carrying out the integration.

With them, you can access the necessary credentialsUnique access keys used to identify an integration in your account, linked to your application. For more information, access the link below.Credentials to interact with our APIs or specific services, as well as manage and organize your integration, which is why you must create an application for each Mercado Pago solution you integrate.

To create an application, follow the steps below.

  1. In the upper right corner of Mercado Pago Developers, click on Login and enter the required information with the data for your Mercado Pago account.
  2. Once you are logged in, in the upper right corner of Mercado Pago Developers, click on Create application if your account does not yet have any created applications, or go to "Your integrations" and select View all. There, click on Create application.
  3. Once inside Your integrations, click on the Create application button.
To protect your account and ensure compliance with operations, during the creation of an application, you will need to do an identity verification if you haven’t done so already, or a re-authentication if you have previously completed the verification process.
