The shortcut to your Gladys
This domain does exactly one thing: send your browser back to your own Gladys instance, at home.
Why this site exists
More and more services (Spotify, Netatmo...) require an HTTPS redirect address to authorize an application. A Gladys instance installed at home answers on a local HTTP address, which can never satisfy that requirement. So you declare this page as the redirect address instead, and it brings you back home once you have granted access.
Nothing is stored here
This page is a static file: no code runs on a server. Everything happens in your browser, which reads the address of your instance, displays it, and sends you there. The authorization code returned by the provider appears in the address of this page, but nothing is stored or used here: it is worthless without your application secret, which never leaves your Gladys. Your access tokens never pass through here — they are exchanged directly between your instance and the provider.
OAuth2 redirect address
This is the address to declare in your developer application (Spotify, Netatmo...). Gladys also displays it for you when you configure the integration.
