VA Rest assistance

Hello everyone. I’m working on an online game and was exploring the use of a Drupal server for the online community. What I’d like to do is also have the game sign into this as well. I know that I can use VARest to construct a statement to send to my server, however, I’m not quite sure how to put the information together that I have gathered. I found this on how to make authenticated REST requests to Drupal Making authenticated requests to REST Server | and I’m looking for some good resources on how to use the VARest plugin to perform the authentication request. Any help would be appreciated, thanks!
