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.
Your client is correctly redirected after the payment is completed.
The payment is divided correctly between your marketplace account and the seller’s account.

How to run tests?

Create test users

To simulate the entire payment process, you must create 3 test users: marketplace, seller and buyer.

Note

In order to test the Checkout Pro all the users involved in the test must be test_users, if not you´ll get the "Invalid users involved" error.

You must make the following API request to create each of the users.

Request

curl -X POST \
-H "Content-Type: application/json" \
-H 'Authorization: Bearer ACCESS_TOKEN' \
"https://api.mercadopago.com/users/test_user" \
-d '{"site_id":"MLA"}'

Response

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

Perform the corresponding tests

The complete process for testing the checkout is as follows:

Log in to Mercado Pago with the marketplace account and generate an APP_ID with all your settings and the URL to send to the seller to connect the seller’s account.
Log in to Mercado Pago with the seller and connect the account to the marketplace, entering the configured URL.
Check whether you have the seller's credentials registered in the marketplace.
Make a test payment. You can send the buyer’s email in the payment preference, or test the flow as a guest. The buyer’s email will be requested at the end of the purchase.
Complete the form, entering the digits of a test card. On the expiration date you must enter any date after the current date and the 3-digit security code.
In the cardholder field, you must enter the prefix corresponding to what you want to test:
- APRO: Payment approved.

- FUND: Payment declined due to insufficient funds.
- SECU: Payment declined by security code.

In case of retry, make sure they are carried out correctly.
