Integration test

It is crucial to test the entire flow before going into production, ensuring that payment creation is done correctly and that messages are effective in communicating with the user. A good experience for your customers at the checkout helps improve conversion.

To perform a test purchase, it is necessary to use the test credentials of your production user. To obtain them, access Application details > Credentials within the Developer dashboard or in your Mercado Pago account by accessing Your Business > Settings > Management and Administration > Credentials.

You can use test cards of local payment methods and simulate different payment responses, without the need to use a real card.

For this, depending on your country, use one of the credit cards we provide below.

Card	Number	Security code	Expiration date
Mastercard	5474 9254 3267 0366	123	11/25
Visa	4075 5957 1648 3764	123	11/25

To test different payment results, fill in the desired status in the cardholder's name (field card_holder_name):

Payment Status	Description
`APRO`	Approved payment
`OTHE`	Declined for general error
`CONT`	Pending payment
`CALL`	Declined with validation to authorize
`FUND`	Declined for insufficient amount
`SECU`	Declined for invalid security code
`EXPI`	Declined due to due date issue
`FORM`	Declined due to form error
`CARD`	Rejected for missing card_number
`INST`	Rejected for invalid installments
`DUPL`	Rejected for duplicate payment
`LOCK`	Rejected for disabled card
`CTNA`	Rejected for non-permitted card type
`ATTE`	Rejected due to exceeded PIN attempts
`BLAC`	Rejected for being on the blacklist
`UNSU`	Not supported
`TEST`	Used to apply amount rules

Test a rejected payment in Automatic Payments Messaging

Below, we present a test scenario to validate the correct functioning of your recurring payments integration.

Use your Checkout API integration to Get card data and create the token.
Create the Customer by sending a POST to the endpoint v1/customers with the email test@testuser.com.
Associate the previously tokenized card to the customer by sending a POST to the endpoint /v1/customers/{customer_id}/cards. You must use the customer_id obtained in the request to create the customer in the path of this request, and send the card_token in the body.
Create the recurring payment without CVV. For the card_holder_name field, enter the value OTHE, which will generate a rejected payment. If you need more information on how to create these payments, go to Automatic Payments Messaging.

        "type": "customer"
    },
    "payment_method_id": "master",
    "transaction_amount": 300
}'

The response to this request should return a rejected payment, according to the data entered for the payment method.
