Provisional endpoint
This endpoint is available for early access. The core schema is stable, but minor details — such as field names or added fields — may change before it becomes generally available. Backward compatibility is not guaranteed.

See API Stability & Versioning for details on provisional endpoints.
When only_latest=true, the from_datetime and to_datetime query parameters are not applied. Only the most recent association per trailer is returned regardless of the date range specified.
When only_latest=false, exactly one vehicle_ids value or one trailer_ids value must be specified. To retrieve association history for multiple vehicles or trailers, make separate requests for each.

Authorizations

​
Authorization
string
header
required

The access token received from the authorization server in the OAuth 2.0 flow.

Query Parameters

​
only_latest
boolean
default:true

​
fleet_ids
string<uuid>[] | null

Limit results to specific fleets using Catena's fleet IDs. For your own fleet identifiers, use fleet_refs instead To specify multiple values, repeat the parameter for each value (e.g., ?fleet_ids=id1&fleet_ids=id2).

Maximum array length: 100
​
fleet_refs
string[] | null

Limit results to specific fleets using your organization's fleet reference identifiers. To specify multiple values, repeat the parameter for each value (e.g., ?fleet_refs=ref1&fleet_refs=ref2).

Maximum array length: 100
