What is PKCE?

PKCE stands for Proof Key for Code Exchange. code_challenge_method and code_challenge are used if the Token Server supports PKCE. It is an extension to authorization_code flow to prevent injection attacks and mitigate other security risks involved when the client is requesting for code from the Token Server.
