Unable to connect to API using HTTP request activity with Oauth1 authentication - Status code:401


I am trying to get to post some data from a URL using API through HTTP request activity with Oauth1 authentication method.
I have entered the base URL in endpoint and added other objects in parameters.
After entering all the details in HTTP request wizard, I was unable to preview the data of the URL. Status code is shown as 401 which is an authentication error.
All the Oauth1 keys were entered correctly. but the issue still persists. If anyone know something about this, Please reply.

Thank You.


Did you test the same in Postman?


Yes, we tried it in postman using signature method. There we are getting correct response.
Where as in UiPath, there is no signature method. Is there any other alternative method or other activities to get the correct response?

Thank you.
