1. Summary 

The APIs allow people/developers to interact with cloud services and manage resources provided by a cloud provider (in our case Shelly Cloud). 

DOCUMENTATION

2.  Features

With the Shelly Cloud API as for now (6/19/23) you can do the following things: 

• get the device's current status
• for relays: switch each output individually 
• for covers: open/close/stop commands and set a position
• for color lights: on/off, update color, update gain for each channel
• for white lights:  on/off, update brightness  for each channel
• groups (multiple relays at the same time/with a single request): only relays as per the documentation 

Support requests types: 

• GET - when fetching information from the server (no changes are required to the database): for getting the device's status
• POST - when changing/uploading new data into the database: for changing the device's output state, color, or settings 

3.  How to use
