Athenthicating OAuth2.0 through Python - Missing or invalid redirect_uri parameter value

[ayala-iu]

Hi,

I'm trying to get access to the Upwork API, using Python. I'm using the official OAuth2 Python library (link), I've followed the installation procedure and I'm running the file "example/myapp.py" (link) as it's indicated in the instructions. I've changed the "client_id" from "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" for the field "Key" in my API key and "client_secret" from "xxxxxxxxxxxxx" for the field "Secret" in my API key.

The main question that I have is what should it be my "redirect_uri"? In the documentation of the API it says: "Redirect URI, must be equal or similar to the callback specified in the key settings. Required for `authorization_code` grant." (link). I've tried two things:

• In my API Key I've left empty the "Callback URL", and set the "redirect_uri" to ""
  
• In my API Key I've set the "Callback URL" to "https://localhost", and set the "redirect_uri" to "https://localhost"
  
  

The program provides me with "authorization_url", but when I insert it in my browser in both cases I get the error message: "Missing or invalid redirect_uri parameter value".

I haven't used much OAuth2.0, so it might be something simple to fix. But given that I only want to get my data in my Python program, I'm not sure what should be my "Callback URI" and "redirect_uri".

Thanks for your help!

I figured it out, I had a typo in my "redirect_uri". If you want to use the Python APi, as I described it works you only need to set:

• In you API Key "Callback URL" to "https://localhost"
• In the code "redirect_uri" to "https://localhost"

I hope it helps.
