Start testing

We do not have a test environment or sandbox to run tests: we make it possible to use test users for verification directly in production. The advantage of working with a test user is that you can simulate between these users of the same actions allowed for a real user –list, update data, ask, answer, purchase, sell, rate, etc.- among test users without paying for any charges or getting penalties, without jeopardizing a real user’s reputation. This tutorial will guide you on how to start working with our API while your app is currently on development.

All test operations must be made out with test users. Remember that personal accounts should not be used for testing.

Create a test user

You need to have a token to create a test user. If you haven’t got your access_token yet, you may read the Authentication & Authorization guide, or you can simply come back here when you are ready to test. You only need to send on the JSON the country where you want to operate. Consult our sites API to know the site_id of each country. We recommend the creation of at least one seller user and one buyer user, to make transactions between them.


curl -X POST -H 'Authorization: Bearer $ACCESS_TOKEN' -H "Content-Type: application/json" -d



Great! On the response you get the User_id, Nickname, Password and current status of your new test user.


When working with test users, you need to take into account the following considerations:

  • You can create up to 10 test users with your Mercado Libre account. (when the test user is created the credentials must be saved, we do not have a resource that displays the created test users and their credentials.)
  • Test users won’t be active for too long, but once they expire, you can create new ones.
  • List under the “Others” category as much as possible.
  • Never list under “gold” or “gold_premium” so it doesn’t get to our home page.
  • Test users can simulate operations only with listings from other test users: they can only buy, sell, ask questions, etc., in test list, created by test accounts.
  • Test users showing no activity (buy, ask, publish, etc.) during 60 days are immediately removed.
  • Test items are removed regularly.
  • The email's validation code for test users will be equal to the last digits of the user id and can have 4 or 6 digits. For example, for user id 653764425, the code could be 764425.

Great! you just finished our Getting Started section. To continue learning, we recommend you to visit our API docs, and choose among our verticals: Products, Real Estates, Vehicles or Services.

Buy and sell between users test

Remember that tests on the platform and all transactions must be done with test users. In addition, personal accounts should not contain ads. If you want to simulate purchases between test users, you could use our test cards. Remember that testing on the platform and all transactions must be done between test users. In addition, personal accounts must not contain listings for this purpose.


- The data to be uploaded is fictitious and, for security reasons, we do not add the names of the banks on the cards available for testing purposes.

- When you access the test card link, you will need to change the URL to the URL of the country you are in. Please note that the link will only be available for countries where Mercado Pago is active.

- To test different payment results, fill in the desired payment status in the cardholder's first and last name when making the purchase. For example, if you want the payment to be approved, you must enter "APRO APRO".
