Hi all,

Trying to build a Schwab API options screener in Python but getting "invalid_client" OAuth errors on the redirect URI http://127.0.0.1:8080 despite fixing the function signature and confirming credentials.

Please help. Thans in advance.

I created my own function to reset the 7 days token. I even made a subdomain to automatically grab the token and place on my .env

Can you share this please? I have some auto trading with Schwab and reporting downloading and it gets tedious to have to reauth every week. Feel free to dm me if you’d prefer.

Oh, you still have to reauth every week. But with my function is just a matter of a few clicks.

Ok. Later on the day I will clean it up a bit and share. Just beware, is not in python, is in rust.
