ario is to get Data from Web thought of using REST API calls and get the items. But when I use HTTP Request activity and pass the API uri facing an error 401.

I can get response using other application like POSTMAN . Also used simple authentication and provided credential. Still same error. Kindly let me know if you have solution for this issue ASAP.

Thanks

I ended up adding the credentials (Add Credential) to the Windows Credential Manager and leaving the authentication properties for the HTTP Request activity unset.
