Integrate with CDK Global DMS via Fortellis

Steps

1. Create a developer account at developer.fortellis.io and register your application in the Fortellis Developer Network.
2. Browse the Fortellis API Directory at apidocs.fortellis.io to find the CDK-published APIs relevant to your use case (service repair orders, parts inventory, vehicle sales, CRM).
3. Subscribe to the desired API in the marketplace; each API subscription requires dealer authorization — the subscribing dealership must also activate the integration in the Fortellis Marketplace portal.
4. Use the OAuth 2.0 client credentials flow to obtain a Fortellis platform access token by posting to the Fortellis authorization server with your application's client credentials.
5. Make API calls by including the access token as a Bearer token and including the required dealer-context headers (such as the dealership identifier) as specified in each API's documentation.
6. For high-volume or event-driven use cases, use the CDK Async APIs available through Fortellis, which deliver data via webhooks rather than synchronous request-response.
