How to set up Server URL Settings for Workflow not for Assistant?

Vapi doesn’t support setting a Server URL directly for a workflow, use the Assistant, Phone Number, or Organization-level Server URL to receive events, or use an API Request node within the workflow to call external services.

Thank you. Is any idea how to get end call report for workflow? Webhook at the and of Workflow not working if customer end call.

Vapi workflows don’t support automatic end-of-call webhooks, so to get a call report, use an API Request node near the end of the workflow to send call data manually to your server..
