Only one type of extension, the callout, is available at this time.


To get the limit on the number of extensions for an advertiser, use the method Clients.get or AgencyClients.get (see the AD_EXTENSIONS_TOTAL element in the Restrictions array).

If there are identical extensions, an error is returned for each of them.
