How Platform API Requests Work

Your server or frontend initiates an HTTP request.
The platform responds, validates the request, and delivers the command to the device.
The device responds and executes the command.
The APIs use HTTP, so any programming language that supports HTTP requests can call them.

How Requests Work After Private Deployment

Private Deployment via Gateway:

Your server or frontend initiates an HTTP request.
The device has a built-in HTTP service and can respond to and execute commands directly.

Private Deployment via Broker:

Your server sends commands to your Broker.
Your Broker responds and delivers the commands to the device.
The device responds and executes the command.
For the specific request methods and principles after private deployment, see Private Deployment Methods or read "《Private Deployment Documentation》". They are not covered in the Open Platform device integration examples.
