What is a connection_id?
Use connection_id to target a specific fleet-to-provider connection.
A connection_id is the unique identifier for a specific pairing between a fleet and one of their TSPs. A carrier that is connected to both Samsara and Motive will have two separate connection IDs.
When reading data (locations, HOS, etc.), the fleet_ref is used and Catena returns data from all connected TSPs automatically. When writing data back to a TSP, the specific connection_id is required so Catena knows which provider to send the request to.
