**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Parameter description: project ID. For details about how to obtain the project ID, see Obtaining a Project ID.
proxy_id	Yes	String	Parameter description: device proxy ID, which uniquely identifies a device proxy. The value of this parameter is allocated by the IoT platform during device proxy registration.

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	No	String	Parameter description: user token. You can obtain the token by calling the IAM API Obtaining a User Token Through Password Authentication. In the returned response header, X-Subject-Token is the desired user token. For details about how to obtain the token, see Token Authentication.
Instance-Id	No	String	Parameter description: instance ID. Unique identifier of each instance in the physical multi-tenant scenario. Mandatory for professional editions and recommended in other cases. Log in to the IoTDA console and choose Overview in the navigation pane to view the instance ID. For details, see Viewing Instance Details.

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
proxy_name	No	String	Parameter description: device proxy name. Minimum: 1 Maximum: 64
proxy_devices	No	Array of strings	Parameter description: device proxy list. All devices in the list share the gateway permission. That is, child devices under any gateway in the list can go online through any gateway in the group and report data. Value: Enter two to ten device IDs in the list. A device ID can contain up to 128 characters, including letters, digits, underscores (_), and hyphens (-). Recommended min. ID length: 4 characters.
effective_time_range	No	EffectiveTimeRange object	Parameter Description: rule validity period.

**Table 4** EffectiveTimeRange
Parameter	Mandatory	Type	Description
start_time	No	String	Time when the device proxy starts to take effect. Format (UTC time): yyyyMMdd'T'HHmmss'Z'.
end_time	No	String	Time when the device proxy expires. The value must be later than the value of start_time. Format (UTC time): yyyyMMdd'T'HHmmss'Z'.
