When is Basic Authentication Supported in Oracle Integration 3?

Oracle Integration 3 supports OAuth 2.0, a token-based authentication method that is more secure. When you upgrade to Oracle Integration 3, we recommend you use OAuth whenever you can. However, this doesn't mean you need to immediately change all your interface connections.

The interface determines which authentication method to use, so some connections will instead use basic authentication or OCI Signature Version 1. For example, when using the Oracle Integration 3 REST API, you must use OAuth, but your existing integrations can still be invoked using basic authentication, and endpoints that are invoked by Oracle Integration can still be called over basic authentication. The following table lists various interfaces, which authentication method they use, and examples of each interface.

Interface	Authentication method	Interface examples
Oracle Integration built-in APIs Oracle Integration 3 REST API File Server in Oracle Integration 3 REST API OCI Process Automation REST API	OAuth Note: OCI Signature Version 1 is not supported	Visual Builder or Process Automation introspecting a list of available integrations Find and resubmit failed integration via API Create a folder in File Server using REST API List processes via API
Oracle Cloud Infrastructure (OCI) lifecycle API and CLI Oracle Integration API	OCI Signature Version 1	Use Python to provision an Oracle Integration instance Use the REST API to add an ACL to an Oracle Integration instance
APIs for integrations you create	Determined by the trigger; could be OAuth, basic authentication, or both Note: OCI Signature Version 1 is not supported	Invoke an integration REST trigger from a mobile application
