4 OAuth 2 and Basic Authentication for EPM Cloud REST APIs

All HTTP requests to the REST APIs require authentication. Review these topics to understand OAuth 2 and basic authentication for EPM Cloud REST APIs.

The REST APIs for EPM Cloud support authentication with OAuth 2 and basic authentication:

EPM Cloud REST APIs can connect to Oracle Enterprise Performance Management Cloud through API Gateways, such as Google APIGEE, IBM Data Power, and other reverse proxy servers.

For this to work, configure the gateway or reverse proxy by setting the target as the URL of your EPM Cloud environment without any context such as /epmcloud. Example: https://epm-idDomain.epm.dataCenterRegion.oraclecloud.com. Then, use the reverse proxy URL instead of the EPM Cloud URL in the REST API. For configuration information, see the documentation of your gateway or proxy server.

While configuring the proxy settings, be sure to pass the response code from EPM Cloud to EPM Cloud REST API without modifying it in any manner to allow REST API processing code to correctly process response codes such as 200, 206, 400, 404, 500, 501, and so on. For example, for IBM Datapower, set proxy HTTP Response to ON. Additionally, the API gateway should allow HTTP methods (GET, POST, PUT, PATCH, and DELETE).
