Credentials


What are my credentials and where can I find them

The credentials are the keys that we provided you so that you could make your integrations.

Your credentials include:

Key Description
Public key Public key of the application that you will use in your frontend and will allow you, for example, to know available payment methods and encrypt card data.
Access token Private key of the application that you will use in your backend to generate payments. It is very important that this data is protected on your servers and is not accessible by any system user or attacker.

They are available in your Mercado Pago account, in the Credentials section.

I am already integrated and tested, how do I implement in production?

To go to production, you must activate your credentials in the Credentials section.

If they are already active, you don't have to do anything.

I want to update my credentials, how can I renew them?

You can renew your credentials from the Credentials section.

For exceptional security reasons, your credentials may need to be updated. But don't worry, you can renew them as many times as necessary.

Keep in mind that you have to replace the credentials you already used with the new ones.
