# DescribeSnapshots
Returns the description of specific Amazon FSx for OpenZFS snapshots, if a `SnapshotIds` value is provided. Otherwise, this operation returns all snapshots owned by your Amazon Web Services account in the Amazon Web Services Region of the endpoint that you're calling.
When retrieving all snapshots, you can optionally specify the `MaxResults` parameter to limit the number of snapshots in a response. If more backups remain, Amazon FSx returns a `NextToken` value in the response. In this case, send a later request with the `NextToken` request parameter set to the value of `NextToken` from the last response.
Use this operation in an iterative process to retrieve a list of your snapshots. `DescribeSnapshots` is called first without a `NextToken` value. Then the operation continues to be called with the `NextToken` parameter set to the value of the last `NextToken` value until a response has no `NextToken` value.
When using this operation, keep the following in mind:
+ The operation might return fewer than the `MaxResults` value of snapshot descriptions while still including a `NextToken` value.
+ The order of snapshots returned in the response of one `DescribeSnapshots` call and the order of backups returned across the responses of a multi-call iteration is unspecified.

{
"Filters": [
{

## Request Parameters
For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).
The request accepts the following data in JSON format.
** [Filters](#API_DescribeSnapshots_RequestSyntax) **
The filters structure. The supported names are `file-system-id` or `volume-id`.
Type: Array of [SnapshotFilter](API_SnapshotFilter.md) objects
Array Members: Maximum number of 2 items.
Required: No
** [IncludeShared](#API_DescribeSnapshots_RequestSyntax) **
Set to `false` (default) if you want to only see the snapshots owned by your Amazon Web Services account. Set to `true` if you want to see the snapshots in your account and the ones shared with you from another account.
Type: Boolean
Required: No
** [MaxResults](#API_DescribeSnapshots_RequestSyntax) **
The maximum number of resources to return in the response. This value must be an integer greater than zero.
Type: Integer
Valid Range: Minimum value of 1. Maximum value of 2147483647.
Required: No
** [NextToken](#API_DescribeSnapshots_RequestSyntax) **
(Optional) Opaque pagination token returned from a previous operation (String). If present, this token indicates from what point you can continue processing the request, where the previous `NextToken` value left off.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 255.
Pattern: `^(?:[A-Za-z0-9+\/]{4})*(?:[A-Za-z0-9+\/]{2}==|[A-Za-z0-9+\/]{3}=)?$`
Required: No
** [SnapshotIds](#API_DescribeSnapshots_RequestSyntax) **
The IDs of the snapshots that you want to retrieve. This parameter value overrides any filters. If any IDs aren't found, a `SnapshotNotFound` error occurs.
Type: Array of strings
Array Members: Maximum number of 50 items.
Length Constraints: Minimum length of 11. Maximum length of 28.
Pattern: `^((fs)?volsnap-[0-9a-f]{8,})$`
Required: No
