检索 GCP 工作流回调 URL

Question

I am trying to trigger a GCP workflow using a scheduler. Workflow Steps can be defined as follows:

1. Make an HTTP API call to another app(Java based running app)
2. Wait for the callback before moving ahead
3. Once callback is received continue with other steps.

Problem: I am unable to retrieve the callback URL for the workflow being executed and therefore my workflow is getting stuck.

I am using Java using which i intend to make the callback call to GCP Workflow engine.
