The Oracle Blockchain Platform administrative (control plane) REST APIs use OCI's authentication mechanism, not the roles and OAuth mechanism used by the instance and transactions (data plane) REST APIs.

The Oracle Blockchain Platform administrative REST APIs are those included in Blockchain Platform Administrative Operations.

For an overview of OCI REST APIs, see Oracle Cloud Infrastructure: REST APIs.

All Oracle Cloud Infrastructure API requests must be signed for authentication purposes. For information about the required credentials and how to sign the requests, see Request Signatures.

OCI's command line interface and SDKs can simplify the use of the OCI REST APIs. See the Oracle Cloud Infrastructure Developer Guide for more information on how to configure and use the OCI CLI and SDKs.
