Hey @likith_rajesh
This is now migrated to Admin → External Applications tab.

Create your confidential application and provide App scopes by getting your client id and secret.
You can then import below Curl command in postman,
curl --location --request POST ‘https://cloud.uipath.com/identity_/connect/token’
–header ‘Content-Type: application/x-www-form-urlencoded’
–data-urlencode ‘grant_type=client_credentials’
–data-urlencode ‘client_id=xxx’
–data-urlencode ‘client_secret=xxx’
–data-urlencode ‘scope=OR.Folders OR.Folders.Read’
You can replace the scope above with your scopes you provide in the External apps configuration (just copy those and paste here).
This will provide you a bearer token in response, which should be used in subsequent requests as a Auth header (Sample below)
curl --location --request GET 'https://cloud.uipath.com/nithinnani07/MyTenant/orchestrator_/odata/Folders' \
--header 'Authorization: Bearer xxx'
Hope this helps
Thanks
