# ModifyDBClusterSnapshotAttribute
<a name="API_ModifyDBClusterSnapshotAttribute"></a>

Adds an attribute and values to, or removes an attribute and values from, a manual DB cluster snapshot.

To share a manual DB cluster snapshot with other AWS accounts, specify `restore` as the `AttributeName` and use the `ValuesToAdd` parameter to add a list of IDs of the AWS accounts that are authorized to restore the manual DB cluster snapshot. Use the value `all` to make the manual DB cluster snapshot public, which means that it can be copied or restored by all AWS accounts.

**Note**  
Don't add the `all` value for any manual DB cluster snapshots that contain private information that you don't want available to all AWS accounts.

If a manual DB cluster snapshot is encrypted, it can be shared, but only by specifying a list of authorized AWS account IDs for the `ValuesToAdd` parameter. You can't use `all` as a value for that parameter in this case.

To view which AWS accounts have access to copy or restore a manual DB cluster snapshot, or whether a manual DB cluster snapshot is public or private, use the [DescribeDBClusterSnapshotAttributes](API_DescribeDBClusterSnapshotAttributes.md) API operation. The accounts are returned as values for the `restore` attribute.

## Request Parameters
<a name="API_ModifyDBClusterSnapshotAttribute_RequestParameters"></a>

 For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

 ** AttributeName **   
The name of the DB cluster snapshot attribute to modify.  
To manage authorization for other AWS accounts to copy or restore a manual DB cluster snapshot, set this value to `restore`.  
To view the list of attributes available to modify, use the [DescribeDBClusterSnapshotAttributes](API_DescribeDBClusterSnapshotAttributes.md) API operation.
Type: String  
Required: Yes

 ** DBClusterSnapshotIdentifier **   
The identifier for the DB cluster snapshot to modify the attributes for.  
Type: String  
Required: Yes

 **ValuesToAdd.AttributeValue.N**   
A list of DB cluster snapshot attributes to add to the attribute specified by `AttributeName`.  
To authorize other AWS accounts to copy or restore a manual DB cluster snapshot, set this list to include one or more AWS account IDs, or `all` to make the manual DB cluster snapshot restorable by any AWS account. Do not add the `all` value for any manual DB cluster snapshots that contain private information that you don't want available to all AWS accounts.  
Type: Array of strings  
Required: No

 **ValuesToRemove.AttributeValue.N**   
A list of DB cluster snapshot attributes to remove from the attribute specified by `AttributeName`.  
To remove authorization for other AWS accounts to copy or restore a manual DB cluster snapshot, set this list to include one or more AWS account identifiers, or `all` to remove authorization for any AWS account to copy or restore the DB cluster snapshot. If you specify `all`, an AWS account whose account ID is explicitly added to the `restore` attribute can still copy or restore a manual DB cluster snapshot.  
Type: Array of strings  
Required: No
