SharePoint Framework - Rest API Tester

A web part that can be used for testing out SharePoint APIs without the hassle of using another application and configuring the right headers.

Rest API Tester


The web part has the following built-in features:

  • Stores the last used query in local browser storage.
  • Ability to store your favorite queries (currently stored in local storage as well).
  • Ability to use tokens in the API URL. These are coming from the this.context.pageContext object from SPFx.
  • API URL Suggestions
  • Allows you to set custom headers and body. The body disabled for GET and HEAD requests.
  • For every request you get the JSON response.
  • Automated conversion of the JSON response to a TypeScript interface.
  • SPFx code snippet for the performed query.

A great way to contribute is to enrich the known APIs file. This file is used for the API URL suggestions. The structure of this file looks like this:

  "api": [

The file is located here: ./src/webparts/restTester/components/known-apis.json.
