redirect_url is not registered

I am working on creating a customized authentication process.

What I need to do is changing the auth_url so it will return the code to our in house endpoint:

But when I test it, I get this error

any idea?

Hi.

Are you changed redirect url in app setting?

In this case, redirect url have to same `https:\\localhost:3000\integrations\hubspot\our_callback`.

Thanks.

I think my situation is I don’t have developer access to HubSpot account, so I cannot get into the page with redirect_url field (screenshot you shown)
