400 Bad Request calling Authorize

Questions
1

My first time working with the Okta API so there may be something obvious here. I’m calling the Authorize endpoint with the following:

https://myoktaurl.com/oauth2/v1/authorize?client_id=MYCLIENTID&response_type=code&response_mode=query&scope=openid&redirect_uri=https://myredirecturl.com/index.html&state=1234567890&nonce=aaaaa32iolkadfoaf2&code_challenge=aaaaaFuass58fCMPpIgFuwvXmcosqdBhEx6c2mCBqrc&code_challenge_method=S256&sessionToken=aaaa19glPbbbb4dHzcXYGFFXqGZMT2D3q3LXoYNccccQ6tIrxJm4rW

This is giving me a 400 Bad Request, both in Postman and from my code. See anything wrong with the request?

Thanks!

I recommend making sure your Client ID that you are passing in is correct (associated with a client created in Okta) and that this client is set to ACTIVE in your Okta tenant. More details in this help article.
