Is it possible to get via API list of all contacts with all properties? I don’t want do that contact by contact because it cost too much calls via API.
There isn’t a way to get all properties when pulling lists of contacts, but you can get specific properties using the
&property= parameter in the request URL. You can include that parameter multiple times to request multiple specific properties.
If you’re still unable to get all of the data you need by using the
&property= parameter (or multiple sets of that parameter), you can get all of the data for contacts in batches, either by the vid or by email.
