Test the integration

Before going into production, it is very important to test the payments flow, checking whether the configurations you made at the preference level are effectively reflected in the checkout.

You should check if:

• The information about the product or service to be paid is correct.
• If you recognize the customer’s account to send the email.
• It offers the payment methods you wish.
• The payment experience is adequate and the payment result is reported.

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

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" \
-H 'Authorization: Bearer PROD_ACCESS_TOKEN' \
"https://api.mercadopago.com/users/test_user" \
-d '{"site_id":"MLC"}'

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

1. Configure the Public Key in your application.
2. Create the preference on your server with the Access Token.
3. Complete the form, entering the digits of a test card. On the expiration date you must enter any date after the current date and a 3-or 4-digit security code, depending on the card.
4. To test different payment results, complete the information you want in the name of the cardholder:

• APRO: Payment approved.
• CONT: Payment pending.
• OTHE: Rejected by general error.
• CALL: Rejected with validation to authorize.
• FUND: Rejected for insufficient amount.
• SECU: Rejected by invalid security code.
• EXPI: Rejected due to problem with expiration date.
• FORM: Rejected by error in the form.

Use these test cards to test the different payment results.

You can also use test credit cards from local payment methods in each country.
