Register at the Toyota developer portal (developer.eig.toyota.com) and request access to the Vehicle API or appropriate API catalog entry for your use case
Review the available APIs including vehicle build information by VIN and connected vehicle telemetry endpoints; note that live data is available for Toyota vehicles manufactured from approximately late 2018 onward
Complete the partner onboarding and data sharing agreement required to receive production credentials
Authenticate using the OAuth flow documented in the portal and obtain tokens scoped to the vehicle data endpoints your integration requires
Retrieve vehicle data such as fuel or battery status, mileage, and location from the available endpoints, noting any make-specific rate limits or data freshness constraints
For European vehicles, consult the separate Toyota developer portal for Europe (developer.toyotaconnected.eu) as the regional endpoints and onboarding process differ
Known gotchas
Toyota's developer ecosystem is split across regional portals (North America uses developer.eig.toyota.com; Europe uses developer.toyotaconnected.eu); using the wrong portal will result in credential or endpoint mismatches
Live telemetry coverage depends on the vehicle being connected and the owner having an active Toyota connected services subscription
Toyota has a strategic data partnership with High Mobility; for normalized cross-OEM access including Toyota, the High Mobility platform may offer a faster path than direct OEM integration
