Example 1: Creating Devices in Batches Using a Template

Scenarios

This topic describes how to create devices in batches using APIs. For details about how to call APIs, see Calling APIs.

The platform allows you to create devices in batches using request parameters or a template. This topic describes how to create devices in batches using a template.

Involved APIs

Procedure

  1. Determine the product to which devices to create belong.

    1. Query the product list
      • API

        URL: GET /v5/iot/{project_id}/products

        For details, see Query the Product List.

      • Example request
        GET https://{Endpoint}/v5/iot/{project_id}/products?limit={limit}&marker={marker}&app_id={app_id}&offset={offset}
        Content-Type: application/json
        X-Auth-Token: ********
        Instance-Id: ********
      • Example response

        Status Code: 200 OK

        Content-Type: application/json
        
        {
          "products" : [ {
            "app_id" : "jeQDJQZltU8iKgFFoW060F5SGZka",
