I'm attempting to authenticate with the Open API v3, but I am hitting a snag authenticating via OAuth2.
When I route the user using my API Key and all of the associated params I get a 404 error.
Here's what I am passing in a GET request (I removed some stuff for this example)
?response_type=code
&client_id=api_keystring
&redirect_uri=https%3A%2F%2Flocalhost%3A44385%2Fauth
&scope=address_r%20billing_r%20listings_r%20profile_r%20shops_r%20transactions_r
&state=40 character random string
&code_challenge=PKCE Code
&code_challenge_method=S256
