This project was heavily influenced by Andrew Connell's SPOAuthFiddlerExt. By heavily influenced, I mean portions of it are the same....exactly the same. I strongly suggest you check out his work and read his article around this plugin. The plugin that he created goes hand in hand with what I've done.

I got tired of not being able to read jwt responses within fiddler so I created this response inspector to decode jwt's within a fiddler response.

Installation Instructions

Copy the following dll's into the 'Inspectors' folder of your fiddler installation

  • FiddlerJwtDecode.dll
  • Newtonsoft.Json.dll

You should see a new tab that says "JWT Decode" in the response pane of the inspectors tab. Also, don't forget to check out "SPOAuth" which is also circled in red.
