Steps
Configure your High Mobility application for fleet access and obtain client credentials (client ID and client secret) from the developer console
Use the OAuth2 client credentials grant to obtain an access token scoped to fleet telemetry endpoints without per-user consent flows
Call the fleet vehicle data REST endpoint to retrieve the latest telemetry snapshot for a vehicle, specifying the vehicle identifier and desired Auto API properties
Parse the normalized Auto API response, mapping brand-agnostic property names to your internal data schema for storage or forwarding to a downstream system
Implement polling or use the High Mobility push mechanism to receive updated telemetry at the frequency your use case requires, respecting the per-vehicle data freshness limits
Handle capability-not-supported responses gracefully: not all vehicles expose all Auto API properties, and responses will indicate which properties were unavailable
Known gotchas
Client credentials flow is intended for fleet or service-account scenarios where the fleet operator has enrolled vehicles; it is not appropriate for consumer-facing applications requiring individual owner consent
Data freshness depends on when the OEM vehicle last synced with the backend; High Mobility returns cached data with a timestamp — do not treat it as real-time without checking the data_updated_at field
High Mobility's normalized schema abstracts OEM differences, but some properties are brand-exclusive; consult the per-OEM capability matrix in the documentation before designing feature requirements
