Product documentation

Now that we have confirmed that PingAuthorize Server is correctly configured to act as a reverse proxy to the Meme Game API, we can define a policy to try out its access control capabilities. This policy will accept or deny a request to create a game based on the identity making the request.

First, we define a service in the Trust Framework. Services have various uses, but at their most basic level, you use them to define a specific API that can be governed by your policies. By defining different services in your Trust Framework, you can target each policy specifically to their applicable APIs.

Then, we define a policy. This policy will reject any requests to start a new meme game if the user's identifier ends with We will identify users using the subject of the request's access token.

  1. Define the service.
    1. Sign on to the Policy Editor using the URL and credentials from Accessing the GUIs.
    2. Go to Trust Framework and click Services.
    3. From the + menu, select Add new Service.
    4. For the name, replace Untitled with Meme Game - Games.

      The service name must match the endpoint name. To understand why, see For further consideration: The PingAuthorize API security gateway, part 2.
