About

This extension allows you to hit API endpoints in your browser by injecting the Client ID and Authorization headers into your request before sending. 

This is done by you providing the extension a TwitchDev application client id, client secret, and refresh token. The extension will allow you to generate a bearer token. Once completed, the extension will inject the client id you provided, and the generated access token in requests made to api.twitch.tv/helix, allowing you to browse the API in your browser (as you would prior to the requirement of these fields).

Changes: 

v1.4:
- Bug fix related to automatic refreshing access token.

v1.3:
- Support for automatically refreshing access token at the determined expiration date/time

v1.2:
- Support for Chrome's Manifest v3. This means removing webRequest and webRequestBlocking in exchange for declarativeNetRequest permission.
- Adds support for using one time "code" values, which are exchanged for bearer and refresh tokens.

As always, you can see the changes at the repo here: https://github.com/swiftyspiffy/Twitch-API-Injector
