Add Virtual Card Address

Save a billing address for virtual card issuance on the caller's account. The address is saved as a BILLING user address and can later be passed to createVirtualCard as userAddressId.

When authUserId is provided, the address is saved for that authorized user's underlying user while remaining attached to the caller's account. The authUserId must be an ACTIVE non-owner authorized user assignment on the caller's account.

If an identical billing address already exists for the target cardholder on the caller's account, the existing address is returned instead of creating a duplicate. Matching is done on address fields, account, target user, and BILLING type.

🔒 Restricted Access

This mutation requires a Bearer token with the CREATE_VIRTUALCARD scope.

mutation AddVirtualCardAddress($input: AddVirtualCardAddressInput!) {
  addVirtualCardAddress(input: $input) {
    userAddressId
    streetAddressLine1
    streetAddressLine2
    country
    city
    state
    postalCode
  }
}
