UiPath errors / Auth

You are not authenticated

platform: UiPath / category: Auth

Cause

The OAuth2 bearer token used for Orchestrator API calls (via HTTP Request or Start Job) has expired or was generated with incorrect client credentials.

Fix

Re-generate the access token from the identity token endpoint with valid client_id/client_secret from your Orchestrator External Application. Confirm grant_type 'client_credentials' and correct scope. In Swagger/Postman, click Authorize again. For long automations, refresh the token before its ~1-hour expiry.
