<p>This is the state parameter that was sent in the initial request. It is used to prevent CSRF attacks.</p> <p>The state parameter is an opaque value used by the client to maintain state between the request and the callback.
Essentially, it is used to prevent Cross-Site Request Forgery (<a href="https://owasp.org/www-community/attacks/csrf" target="_blank">CSRF</a>) attacks and to ensure the response belongs to the request made by the client.

<p>Session state is a parameter that is used to maintain state between the request and callback. It is used to prevent CSRF attacks.</p> <p>The session state parameter is not a core part of the OAuth 2.0 specification, but it is used in OpenID Connect (OIDC)
to represent the state of the end user's session at the Authorization Server.
The client can use this value to help manage user sessions or to detect when the user's session at the Authorization
Server changes (for example, if the user logs out).</p>

<p>This is the authorization code that will be exchanged for an access token.</p> <p>The code parameter contains the actual authorization code. This is a temporary code that the client can exchange for an
access token (and optionally, a refresh token) by making a back-channel request to the Authorization Server.
The format and structure of the code is determined by the Authorization Server. It can be just a random string, or a more complex construction. The exact significance of this structure is specific to the Authorization Server implementation and might include different identifiers or information encoded in
the structure.</p>
