Introduction

Mangopay cards must be validated (Validity value is VALID) within 24 hours after the card registration. This can be done by making a successful pay-in with the card (direct, preauthorized, recurring, etc). See How to process a card payment for the complete flow of a one-off card payment.

Alternatively - and particularly if the card is not going to be used within 24 hours - you can use the card validation feature to perform 3DS authentication without debiting the card.

This guide focuses on how to perform a card validation.

Prerequisites

  • A ClientId and an API key – if you don’t have these, contact Sales to get access to the Mangopay Hub
  • A User object created for your end user
  • A CardId for the end user’s card (CardType must be CB_VISA_MASTERCARD), obtained through the card registration flow or returned by the Mangopay Vault SDK or Checkout SDK – in Sandbox, we recommend you use the challenge test card
  • The URL of a page on your platform to return the end user to after authentication

​
1. Request the card validation

Using the User’s Id as the AuthorId, use the Create a Card Validation endpoint to make the request for validation without a payment.

When you make the card validation request, you also need to:

  • Be ready to handle 3DS authentication (Step 2)
  • Specify the page to which the user will be returned after authentication (Step 3)

Read these steps before continuing.

POST /V2.01/{ClientId}/cards/{CardId}/validation

    }
}

​
2. Redirect the user to 3DS protocol (if required)

Redirect the user to the SecureModeRedirectURL value to complete strong customer authentication.

In the case of the Card Validation, it is highly unlikely that the value will be null (indicating that 3DS is not required and no redirection is needed).

You can also use the SecureModeNeeded boolean to determine this redirection behavior.

See the 3DS article for more information.

Note - Card validation expires after 5 minutes

Because you cannot create two requests at once for the same card, the card validation will expire after 5 minutes, setting the Status of the Card Validation object to FAILED.

The Card Validity, however, will remain UNKNOWN, which allows you to request a new Card Validation.

​
3. Redirect the user after authentication

After the card validation, whatever the authentication outcome, the end user is returned to the SecureModeReturnURL which you defined.

The Mangopay API returns your SecureModeReturnURL with the Id of the card validation attached as a query parameter in the following format:

https://www.example.com?cardValidationId=Id

Mangopay updates the Status of the card validation to indicate the outcome of the end user’s authentication.

You can set up the following hooks to be notified of the outcome:

NameResourceIdDescription
CARD_VALIDATION_CREATEDCardValidationIdThe Card Validation object has been created and the card is pending validation.
CARD_VALIDATION_FAILEDCardValidationIdThe Card Validation has failed, setting the corresponding card as invalid.
CARD_VALIDATION_SUCCEEDEDCardValidationIdThe Card Validation has succeeded, setting the corresponding card as valid.

​
Handling errors

The card validation endpoints contain HTTP error examples, such as when a card validation is already in progress or the card is already valid or invalid.

In terms of functional errors, the card validation endpoints may return the same errors as other card pay-in requests.
