Enum ClientAuth 

pub enum ClientAuth {
    Basic,
    Body,
}

How the client proves who it is at the token endpoint, RFC 6749 §2.3.1.

The RFC gives two ways and says a server MUST support the first, but plenty only implement the second — and a provider handed credentials the way it does not expect answers invalid_client, which reads exactly like a wrong secret. That is why this is a property of the provider and not a guess.

Variants

Basic

HTTP Basic, with the id and secret percent-encoded before they are joined and base64’d — §2.3.1 is explicit about the encoding, and a secret containing : or + is silently wrong without it.

Body

client_id and client_secret as ordinary form fields.
