Activity bindings

A CRM activity — a call, meeting, task or email — shows up in the timeline of the record it belongs to. Bindings make a single activity appear in several cards at once: for example, a call is visible both in a deal and in a smart-process card.

Bitrix24 API: crm.activity.binding.* Scope: crm

List bindings

GET /v1/activities/:activityId/bindings

Returns every CRM entity the activity is bound to. There is always at least one binding — the owner entity set when the activity was created.
