If someone clicks a frame and it redirects you to an external website, is there a way for the external website to know the user's FID without having to sign in with Warpcast?

Yes. On frame's first page, user would need to press say a "Start" button. This calls the post_url on your server with the FID. In response to this, the server will send back a new frame, with redirect button that has the target url appended with query param of ?fid=123 User then clicks this btn to get redirected

Does the external website belong to the frame developer?

Yes when someone taps a frame button it also posts a signed message that you can validate to get info about the user @rish and neynar has an api that lets get this data easily or you could homebrew it

Just add the fid to the query string in URL.

yes post_redirect can forward data theoretically either via query params or other

Yes: frame actions (buttons or text input). No: frame url (user clicks on web url)

If you control the frame you could encode it into the URL, in a query param for example Haven’t fully thought it through but I don’t think there’s a secure way to use the frame redirect to actually log a user in, but you could definitely identify them at least
