title: Revoke Rails Doorkeeper Token via POST
body: <p>We know if we utilise the Resource Owner Password Credential flow for doorkeeper, the generated JSON params for POST are based on the URL <a href="https://github.com/doorkeeper-gem/doorkeeper/wiki/Using-Resource-Owner-Password-Credentials-flow" rel="nofollow noreferrer">here</a>:</p>
  <pre><code>{
    &quot;grant_type&quot;    : &quot;password&quot;,
    &quot;username&quot;      : &quot;user@example.com&quot;,
    &quot;password&quot;      : &quot;sekret&quot;,
    &quot;client_id&quot;     : &quot;the_client_id&quot;,
    &quot;client_secret&quot; : &quot;the_client_secret&quot;
  }
  </code></pre>
  <p>I would like to perform a token revocation via POST to /oauth/revoke; thus, what parameters which I need in order to perform the POST via JSON?</p>
  <p>Thanks!</p>
