API Sample Request

This topic describes how to use Postman to make API requests and control devices. A robot vacuum is used as an example in this topic.

Prerequisites

• The device is associated with the IoT Development Platform. For more information, see Link Devices.
• You are authorized to make required API requests. For more information, see Apply for Access to API Groups.
• The required Postman environment is configured. For more information, see Set up a Postman Environment.

Procedure

1. Get a token.
   Call the Get access_token with simple mode operation to get the value of access_token. The value is required when you call API operations to control devices.
   

2. Call the Get the function list operation to get the instruction set that is supported by the device. You can use the instruction set to control the device.
   

3. Call the Send device commands operation to control the device. You can send a command that is supported by the device to achieve the required effect.

   Note: For more information, see API Reference.

The following code block in the API request body shows how to start a robot vacuum:

		{
			"code": "power",
			"value":true
		}
