No parameters

Authorization

The supported authorization model uses OAuth 2.0 scopes issued by OCI Identity Domains. Send the access token as a bearer token. Resource-server definitions and issued access-token claims use canonical system/... scopes. Client grants and token requests use the corresponding ddfssystem/... form. For examples, see Reference: Authentication and Scopes.

Context	Scope form
Resource-server definition	`system/Observation.c`
Client grant/token request	`ddfssystem/Observation.c`
Issued token's `scope` claim	`system/Observation.c`
