Test your integration

How to test my integration

Test users allow you to test your Smart Checkout by generating payment flows in an exact copy of your integration.

User types Description
Seller It is the test account you use to configure the application and credentials for collection.
Buyer It is the test account you use to test the purchase process.
There are two ways to make the payment:

As a guest user: you only need to complete the email address.
As a registered user: you access the Mercado Pago account with the username and password. In case money is available in the account or there are saved cards, they will be enabled as payment methods.

How to create users

To perform the tests it is necessary that you have at least two users: a buyer and a seller.

Execute the following curl to generate a test user:



curl -X POST \
-H "Content-Type: application/json" \
"https://api.mercadopago.com/users/test_user?access_token=PROD_ACCESS_TOKEN" \
-d '{"site_id":"MLA"}'



    "id": 123456,
    "nickname": "TT123456",
    "password": "qatest123456",
    "site_status": "active",
    "email": "test_user_123456@testuser.com"


  • You can generate up to 10 test user accounts simultaneously. Therefore, we recommend you save each email and password.
  • Test users expire after 60 days without activity in Mercado Pago.
  • To make test payments we recommend using low amounts.
  • Both buyer and seller must be test users.
  • Use test cards, since it is not possible to withdraw money.
