Calling Method

For details, see Calling APIs.

URI

GET /v2/reverse/floatingips

Table 1 Query Parameters

Parameter

Mandatory

Description

marker

No

String

Start resource ID of pagination query. If the parameter is left blank, only resources on the first page are queried. It is left blank by default.

limit

No

The value ranges from 0 to 2147483647. The default value is 0.

If marker is not left blank, the query starts from the resource specified by marker.

enterprise_project_id

No

String

ID of the enterprise project associated with the PTR record. The value contains a maximum of 36 characters.

Default value: 0

tags

Parameter

Type

Description

links

pageLink object

Link of the current resource or other related resources. When a response is broken into pages, a next link is provided to retrieve all results.
