Creates or extends an existing presence session for a user or device within a location. This endpoint should be polled on a set interval while the user is present in the space, using a TTL that is longer than that interval.

The response will either be 201 if the session is newly created or 200 if updated (extended).

🚧
Keep your presence intervals short
Presence should be posted at a heartbeat interval that is less than the provided TTL. Otherwise, undesired unique presence sessions will be created for every single post instead of properly extending a single session.
If this behavior is detected, the access token at fault for the abuse may be revoked.
