!!! Overview
[{$pagename}] is defined in the [IANA Registry]: [OAuth Parameters Registry] ([IANA Registry]) from [OAuth 2.0 Token Revocation].

!! [OAuth 2.0 Token Revocation] ([RFC 7009])
[{$pagename}] as an [OPTIONAL] hint about the type of the [token] submitted for [Revocation Request].  [OAuth Clients] [MAY] pass this parameter in order to help the [Authorization Server] to optimize the token lookup.  If the server is unable to locate the token using the given hint, it [MUST] extend its search across all of its supported token types.  An [Authorization Server] [MAY] ignore this parameter, particularly if it is able to detect the token type automatically.  [OAuth 2.0 Token Revocation] ([RFC 7009]) defines two such values:
* [access_token]: An access token as defined in [RFC 6749], Section 1.4
* [refresh_token]: A refresh token as defined in [RFC 6749], Section 1.5

[UMA 2.0 Grant for OAuth 2.0 Authorization] 3.7 Client Requests [Token Revocation]
If the [Authorization Server] presents a [Token revocation] endpoint] as defined in [RFC 7009], the client [MAY] use the endpoint to request revocation of an [RPT] (access token), refresh token, or [PCT] previously issued to it on behalf of a requesting party. This specification defines the following token type hint value:
* pct - Helps the authorization server optimize lookup of a [PCT] for [Token Revocation].
