Invoke the OAuth Introspection Endpoint

The OAuth Introspection Endpoint is as follows:

https://localhost:9443/oauth2/introspect

Use the following cURL commands to invoke the OAuth introspection endpoint.

OAuth 2.0 Token Introspection defines a protocol that allows authorized protected resources to query the authorization server to determine the set of metadata for a given token that was presented to them by an OAuth Client. This metadata includes whether or not the token is currently active (or if it has expired or otherwise been revoked), what rights of access the token carries (usually conveyed through OAuth 2.0 scopes), and the authorization context in which the token was granted (including who authorized the token and which client it was issued to). Token introspection allows a protected resource to query this information regardless of whether or not it is carried in the token itself, allowing this method to be used along with or independently of structured token values.

The states and descriptions of authorization codes and access tokens are given below:

Authorization Codes:
1. ACTIVE - Valid and yet to be exchanged for an access token.
2. INACTIVE - Invalid and already being exchanged for an access token.
3. EXPIRED - Invalid as it got expired before being exchanged to an access token.

Access Tokens:
1. ACTIVE - Valid access token. Although the state is ACTIVE, the timestamp calculation may reveal it to be EXPIRED, but this happens only during the first access token request or token validation request after expiration.
2. INACTIVE - Refreshed using refresh_token grant type before expiration. Also this state is used in cases when users and user stores are deleted, user passwords are updated, etc.
3. EXPIRED - Invalid and expired access token. Refresh token can still be valid though.
4. REVOKED - Revoked access token. Refresh token also gets revoked along with access token. Access token could have been in ACTIVE or EXPIRED state while revoking.

For requests that require CLIENT_ID:CLIENT_SECRET, use the client Id and client secret of the OAuth application.
For requests that require USERNAME:PASSWORD, by default you can use credentials of any user with "/permission/admin/manage/identity/applicationmgt/view" permissions. To allow users with other permissions to send validation requests, edit the following property found under the <ResourceAccessControl> tag of the <IS_HOME>/repository/conf/identity/identity.xml file.
```
<Resource context="(.*)/oauth2/introspect(.*)" secured="true" http-method="all">
    <Permissions>/permission/admin/manage/identity/applicationmgt/view</Permissions>
</Resource>
```
