\# Integration Test After creating the Zero Dollar Auth validation, it is important to perform integration tests to confirm its functionality. To test the validation, there are two steps: \* Generate card token \* Validate integration ## Generate card token To test the Zero Dollar Auth validation, the first step is to generate a card token. To do this, use our \[Mercado Pago SDK JS\](https://www.mercadopago.com.co/developers/en/docs/sdks-library/landing) library to capture card data and generate the token. To obtain the card token, use the test data that we share with you in the table below. > WARNING > > Important > > To simulate \*\*approvals\*\*, use the specific card \`4074090000000004\`. To simulate \*\*rejections\*\*, use any other card. | Value | Example | |---|---| | Card number | 4074090000000004 | | Expiration month | 02 | | Expiration year | 2031 | | Security code | 123 | | Cardholder name | APRO | | Identification type. It can be one of the following types:  
CPF: Individual Taxpayer Registration, Brazil.  
CNPJ: National Register of Legal Entities, Brazil.  
CUIT: Unique Tax Identification Code, Argentina.  
CUIL: Unique Labor Identification Code, Argentina.  
DNI: National Identity Document, Argentina.  
CURP: Single Population Registration Code, Mexico.  
RFC: Federal Registry of Taxpayers, Mexico.  
CC: Citizenship Card, Colombia.  
RUT: Single Tax List, Chile.  
CI: Identity Card, Uruguay. | CPF | | Document number | 15635614680 | > WARNING > > Important > > In order to perform transactions with the card data open, directly in the API call, it is necessary for the seller to be \[PCI Compliant\](https://www.mercadopago.com.co/developers/en/docs/security/pci). Otherwise, these data cannot be transacted in the backend of your application. ## Validate integration As a last step, it is necessary to validate the integration using the token obtained in the previous step. To do this, send the parameters described in the table below to the \[/v1/payments\](https://www.mercadopago.com.co/developers/en/reference/online-payments/checkout-api-payments/create-payment/post) endpoint and execute the request. | Parameter | Type | Description | Example | |---|---|---|---| | token | String | Card token | 12346622341 | | payment\_method\_id | String | Indicates the identifier of the payment method selected to make the payment | master | | payer.email | String | Payer's email | buyer@examplemail.com | | payer.type | String | Type of identification of the associated payer | guest | | description | String | Description of the validation | "zero dollar card validation with master credit without cvv" | | transaction\_amount | Number | Cost of the validation | Always zero (0) for Zero Dollar Auth | \`\`\`curl curl -X POST \\ 'https://api.mercadopago.com/v1/payments'\\ Content-Type: application/json X-Card-Validation: card\_validation Authorization: Bearer {{access\_token}} { "token": "{{card\_token}}", "payment\_method\_id": "master", "payer": { "email": "{{payer\_email}}", "type" : "guest" }, "description": "validação de cartão com valor zero dollar master crédito sem cvv", "transaction\_amount": 0 } \`\`\`
