Group Call

A group call is a call in product-analytics SDKs that associates a user with a group or account — such as a company or workspace.

A group call is the sibling of the identify and track calls: identify says 'who is this user', track says 'what they did', and group says 'which account they belong to'. It is this call that makes group analytics possible, because without it there is no way to roll individual behavior up to the account level. One user can belong to several group types (a company and a team, say), and each group type is defined by a key. The important point is that this mechanism belongs to product-analytics tools with a known-user model; a web analytics tool whose unit is the visitor and the session usually has no such call and keeps behavior at the individual level.
