A very simple process, just to illustrate how easy this is with OPA.
I Activate and then click on View API -
So now I have the endpoint - I need to authenticate via OAuth; so before I can test this I need to register my Oracle Cloud Infrastructure Process Automation instance as a confidential application in Oracle Identity Cloud Service.
And yes, I still use Windows, or, as we say, in Gaeilge - fuinneoga.
So, I've now got encoded client id and secret as well as the authorization code - time to get the auth token -
curl -i -H "Authorization: Basic yourBase64EncodedClientIdSecret" --request POST "https://yourIDCSUrl/oauth2/v1/token" -H "Content-Type:application/x-www-form-urlencoded" -d "grant_type=authorization_code&code=yourAuthorizationCode"
I take the code and now set up the invoke of my Process in Postman -
Here is the OAuth Configuration -
Note: Scope is set to https://yourOPA.process.oci.oraclecloud.com/process
I enter the process payload - my Order -
and test - I see the following error message in Postman -
Quite correct, I have not assigned any users to my Process role. I return to Process Workspace and do this -
Now back to Postman -
That's more like it!
Invoking OPA REST APIs is simple, once you have done the initial setup.
Final step - I validate in OPA Workspace -
