In a previous post, I showed how to inspect a SharePoint 2013 context token. While working with apps, I frequently demonstrate how the context, refresh, and access tokens work. I realized that it might be helpful to see the actual tokens while working with an app. Instead of writing more code in my web page to show the information, I decided to use Fiddler instead. The result is a handy extension for Fiddler that SharePoint 2013 app builders can use to inspect the context and access tokens for your apps for provider hosted apps using either a client secret or a certificate.
