Thank you all for the quick responses. However, I am having an issue with that endpoint, and am assuming I am doing something wrong :)

I am making the request with a Bearer authorization header containing the token of a client that has the admin role in it's service account. I am testing that the client token is valid via the following curl call:

curl -s -X GET -H "Authorization: Bearer $_CLIENT_TOKEN" 'http://localhost-docker:8080/auth/admin/realms/master/users'

However, when I make the following curl request for token introspection:

curl -v -X POST -H "Authorization: Bearer $_CLIENT_TOKEN" --data "token=$_INTROSPECT_TOKEN" \
   'http://localhost-docker:8080/auth/realms/master/protocol/openid-connect/token/introspect'

... I get the following response:

> HTTP/1.1 401 Unauthorized
> Connection: keep-alive
> X-Powered-By: Undertow/1
> Server: WildFly/10

> {"error_description":"Authentication failed.","error":"invalid_request"}

... and the following console error output:

Is there another method I should be using to authenticate the client for this request? Is there something else that you see that I am doing wrong?

Make a POST sending "token" as request parameter to
/realms/{realm}/protocols/openid-connect/token/introspect
