**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
marker	No	String	The ID of the resource from which the pagination query starts. It is the ID of the last resource on the previous page.
offset	No	Integer	The offset. NOTE: This parameter is used when snapshots are queried by page and is used together with the limit parameter. For example, there are a total of 30 snapshots.

If the tenant has more than 50 snapshots in total, you are advised to use this parameter and set its value to 50 to improve the query efficiency. Examples are provided as follows: Querying 1–50 snapshots: GET /v2/xxx/snapshots?limit=50; Querying 51–100 snapshots: GET /v2/xxx/snapshots?offset=50&limit=50
name	No	String	The snapshot name. This parameter does not support fuzzy match. You can enter up to 255 characters.
status	No	String	The snapshot status. For details, see EVS Snapshot Status.
volume_id	No	String	The ID of the snapshot's source disk.
