Create multiple associations between CRM objects. The JSON data in the PUT request would be a list of associations, with each one representing a single association between 2 objects (for example, a ticket to a contact). To associate one object with multiple other objects (i.e. to associate a ticket with 2 different contacts), you would need to include multiple association entries (one for associating the ticket with contact A, and another to associate the ticket with contact B).

Up to 100 associations may be created in a single request.

Returns a 400 response if there are any issues with the association. If there are any errors, the entire request will fail and none of the associations will be created.
