Can't complete first stage of authentication to obtain code

Help
1

Hello,

I’m building a personal app and trying to set up authentication although can’t seem to get past the first stage. Here are the steps I have done:

  • Built an OAuth client in Monzo for Developers
  • Set it to Confidential

I have the client_id and client_secret although can’t seem to get to the point where I authenticate in my app. I’m using Python and have a url which looks like this:

https://auth.monzo.com/?client_id={client_id}&redirect_uri={redirect_uri}&response_type=code&state={random_string}

I have tried:

  • Pasting this into a browser and then trying to get it to email me a link. It gives me a network error after putting in my email address
  • Pinging this with a get request which gives me a 200 although then nothing happens

If I don’t have a web page to redirect this too, what should I use for the redirect URI? I currently have https://developers.monzo.com as the redirect_uri

What do I do with this URL?

I feel like I’m missing something really basic here. Cheers!
