I'm trying to call Alteryx Gallery REST API from python. For this I had gone through 'https://gallery.alteryx.com/api-docs/#subscription' selected the endpoint /api/v1/workflows/subscription/ and got the request URL. Copied the URL and pasted in Postman with key and secret got from 'Keys' section in user profile and I can get the response with OAuth1.0. Now I'm trying to do the same with python, unfortunately I'm getting error with (401,
'{"data":null,"exceptionName":"UnauthorizedException","innerExceptionMessage":"","message":"The provided signature(oauth_signature) is invalid."}').
I hope the error is with creating signature. Can you please check and help me to fix the error. I had attached my python script as well.
