Connect Clocktowertimer to Spotify API

You can connect Clocktowertimer to the Spotify API. In doing so, Clocktowertimer will automatically adjust the playback volume of the currently active device on Spotify.

At Dawn the volume is 50%.
At Dusk the volume is 30%.
At Night the volume is 80%.

These values may also be configured using URL-parameters:

https://clocktowertimer.com?volume=[50,30,80]

Requirements

Please pay attention to the following requirements:

The API only works for users who have Spotify Premium.
As Clocktowertimer is under steady development this feature is not yet finished. Therefore, you have to generate your own Spotify-App in the Developer-Center. Or send your name and email address registered with Spotify to [email protected].

Create a Spotify App

This part is equivalent to https://developer.spotify.com/documentation/web-api/tutorials/getting-started#create-an-app.

Create an app in the Developer Dashboard (login and click on Create an app).
App Name: Your own choice
App Description: Your own choice
Redirect URI: https://clocktowertimer.com/spotify.html
Which API: Web API

Afterwards copy your apps Client ID from the app's settings page and enter it here:

The Client ID will only work with Spotify Accounts approved by the Spotify app's developer. If you insert the default Client ID '9c288c96571e470db82a242089fb9cf6' (or leave the field empty) you have to contact Dennis Schürholz as stated above. If Spotify approves Clocktowertimer as a Spotify webapp this step will no longer be required.
