The virtual business card (VCard) object contains the advertiser's contact information. For more information, see vCards in the Help for Yandex.Direct.
An ad can only have one vCard (or none). The same vCard can be added to multiple ads.
Use the VCards service for creating and deleting vCards.
You can't edit vCards. If you need to change the vCard, create a new one and assign it to the ad.
To add a vCard to an ad or remove it from an ad, use the Ads service (see Adding vCards, images, sitelinks, callouts, and video extensions to an ad).
A vCard undergoes review only when it is assigned to an ad (see Result of reviewing add-ons).
You can delete a vCard only if it is not assigned to any ads. To get a list of ads that a particular vCard is assigned to, use the Ads service.
