I have created two workflows, main workflow and a subprocess workflow. Subprocess workflow has a “External Trigger”. Main workflow gets triggered when a new identity is created and then it uses the HTTP Request Action to call the subprocess workflow.
In the subprocess workflow, I have generated an Access Token that I am using in the main workflow to call the subprocess workflow.
I have tested this with the Test Workflow button on the workflow as well as automation. It gets stuck on the HTTP Request Action and does not give any error. I have also tested calling another SailPoint API but it gets stuck in the HTTP Request everytime.
Can I know how you are calling the second workflow (subprocess)? Did you configure external trigger clientID, clientSecret and ClientURL in your main workflow?
