Host: graph.facebook.com
/* PHP SDK v5.0.0 */
/* make the API call */
try {
  // Returns a `Facebook\FacebookResponse` object
  $response = $fb->post(
    '/{event-id}/attending',
    array (),
    '{access-token}'
  );
} catch(Facebook\Exceptions\FacebookResponseException $e) {
  echo 'Graph returned an error: ' . $e->getMessage();
  exit;
} catch(Facebook\Exceptions\FacebookSDKException $e) {
  echo 'Facebook SDK returned an error: ' . $e->getMessage();
  exit;
}
$graphNode = $response->getGraphNode();
/* handle the result */
/* make the API call */
FB.api(
    "/{event-id}/attending",
    "POST",
    function (response) {
      if (response && !response.error) {
        /* handle the result */
      }
    }
);
/* make the API call */
new GraphRequest(
    AccessToken.getCurrentAccessToken(),
    "/{event-id}/attending",
    null,
    HttpMethod.POST,
    new GraphRequest.Callback() {
        public void onCompleted(GraphResponse response) {
            /* handle the result */
        }
    }
).executeAsync();
/* make the API call */
FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                               initWithGraphPath:@"/{event-id}/attending"
                                      parameters:params

                                      NSError *error) {
