Set the token value in the `Authorization: Bearer ` header. **Service Access Token**: Scoped to a single service. Use when automating service-level configuration or runtime flows. **Organization Token**: Scoped to the organization; inherits permissions across services. Use for org-wide automation or when managing multiple services programmatically. Both token types are issued by the Authlete console or provisioning APIs. ````
