The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.
About Twitch Auth Token Sync
Once installed, click the extension in the browser toolbar to configure the following settings:
1. Destination: The destination *must* be a URL capable of receiving Twitch EventSub-style webhook callback notifications[1]. This is where the extension will send notifications.
2. Encryption Key: You must provide an encryption key used to encrypt the 'auth-token' cookie value. This key can be any arbitrary value of your choice, and will be used later to decrypt the cookie value.
3. Signing Key: You must provide a 'secret' value used to sign notifications. This value must be the same value used by your webhook callback for signature verification[2] to succeed.
You can force the extension to send a notification by changing any one of its setting values.
The extension will not send notifications unless all of its settings have been configured.
