Do I need a key or ID to authenticate a blockstack user

I want to make a blockstack site but do I need some kind of API key or ID to use a blockstack sign in?

@vooids You don’t need an API key as a developer. The user would need a blockstack id.

As a developer you need a domain (best served from a https location).

I have a blockstack ID. Is there a place I would need to input it for the redirect to work?

No, why do you think you should enter it somewhere? What is not working for the redirect? You could also ask for help on discord
