# DeleteAssociation
<a name="API_DeleteAssociation"></a>

Disassociates the specified AWS Systems Manager document (SSM document) from the specified managed node. If you created the association by using the `Targets` parameter, then you must delete the association by using the association ID.

When you disassociate a document from a managed node, it doesn't change the configuration of the node. To change the configuration state of a managed node after you disassociate a document, you must create a new document with the desired configuration and associate it with the node.

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

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.

 ** [AssociationId](#API_DeleteAssociation_RequestSyntax) **   <a name="systemsmanager-DeleteAssociation-request-AssociationId"></a>
The association ID that you want to delete.  
Type: String  
Pattern: `[0-9a-fA-F]{8}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{4}-[0-9a-fA-F]{12}`   
Required: No

 ** [InstanceId](#API_DeleteAssociation_RequestSyntax) **   <a name="systemsmanager-DeleteAssociation-request-InstanceId"></a>
The managed node ID.  
 `InstanceId` has been deprecated. To specify a managed node ID for an association, use the `Targets` parameter. Requests that include the parameter `InstanceID` with Systems Manager documents (SSM documents) that use schema version 2.0 or later will fail. In addition, if you use the parameter `InstanceId`, you can't use the parameters `AssociationName`, `DocumentVersion`, `MaxErrors`, `MaxConcurrency`, `OutputLocation`, or `ScheduleExpression`. To use these parameters, you must use the `Targets` parameter.
Type: String  
Pattern: `(^i-(\w{8}|\w{17})$)|(^mi-\w{17}$)`   
Required: No

 ** [Name](#API_DeleteAssociation_RequestSyntax) **   <a name="systemsmanager-DeleteAssociation-request-Name"></a>
The name of the SSM document.  
Type: String  
Pattern: `^[a-zA-Z0-9_\-.:/]{3,128}$`   
Required: No
