A while back I made some utilities I developed to help with managing the API Platform. At the time we didn’t have access to an IDCS based environment, so credentials worked using basic auth (I.e. user name and password). But with environments managed by IDCS tokens are used.

As a developer with a Java background I have to admit to liking Groovy over Python for scripting, not to mention for the API Platform groovy is part of the gateway deployment and SDK. Meaning it is readily available in its 2.x form (3.x is relatively recent and aligning to the latest Java idioms). We haven’t tested against Groovy 3.0

Thank you to Andy Knight for sharing with us some Java code which I adapted to be pure Groovy (removing external dependencies for processing JSON). The result is a script that can taken can be taken and worked into other scripts (which is what we have done for our previously provided scripts – Understanding API Deployment State on API Platform, Managing API Policy Versioning in Oracle API Platform, Documenting APIs on the Oracle API Platform). But this script can be used to get a token and display it on the command line or write it to file. Writing tokens to files is generally not good practise, but as a temporary measure when working on developing scripts arguably a managed risk.

The script can be found at https://github.com/mp3monster/API-Platform-Utils/tree/master/getToken and all the details on using the script can obtained by passing -h as a parameter. The important thing is to understand how to obtain the Client ID and Client Secret, the details of which are described at https://docs.oracle.com/en/cloud/paas/api-platform-cloud/apfad/find-your-client-id-and-client-secret.html
