Querying the Central Network List

Function

This API is used to query the central network list.

Parameters marker and limit are used for pagination query. The default value of limit is 0. If marker is not specified, the first data record is returned.

Calling Method

For details, see Calling APIs.

URI

GET /v3/{domain_id}/gcn/central-networks

domain_id	Yes	String	Account ID.

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
limit	No	Integer	Number of records on each page. Value range: 1 to 1000
marker	No	String	Pagination query information. You can obtain the marker values from the response of the last API call. You can enter the marker value of the previous page or the next page.
