Card

Cards are an essential part of the bunq experience—and just like everything else, each Card is directly linked to a User.

Every card must be connected to a MonetaryAccount, since that’s where the money comes from (and goes to). A single monetary account can be linked to multiple cards, but each card can only have one primary account. If there aren't enough funds in the primary account, bunq will check the secondary account (if set). If both are empty, the transaction will fail.

Cards also play a key role in 2-factor authentication, using the user’s PIN to authorize payments. These card payments are stored as regular Payment records and can be viewed via: GET /user/{userId}/monetary-account/{monetaryAccountId}/payment

Want to see card-specific transaction details? You’ll need to query the MasterCardAction endpoint: GET /user/{userId}/monetary-account/{monetaryAccountId}/mastercard-action
