Authenticate and interact with Decisiv SRM service cases via the Platform API

Steps

1. Contact Decisiv to have an OAuth Application (client ID/secret pair) provisioned and Platform API or SRM Connect API access enabled for your account.
2. If migrating from legacy auth, generate a transition token inside the Decisiv Case application under Admin > Customize Your Database > Platform API.
3. Request an access token from the OAuth token endpoint using the password grant type, supplying your application credentials and a Decisiv user login.
4. Include both the Authorization bearer-token header and the transition-token header on every Platform API request during the OAuth transition period.
5. Use the documented Accept/Accept-Version headers per endpoint, since the Platform API exposes multiple concurrent schema versions side by side (e.g., an older beta version and v1).
6. For fleet-side asset/case integration rather than service-provider workflows, use the separate SRM Connect API, which has its own Swagger documentation and host.
