.. py:method:: CloudWatchLogs.Client.put_destination_policy(**kwargs)

  

  Creates or updates an access policy associated with an existing destination.

  **Request Syntax**
  ::

    response = client.put_destination_policy(
        destinationName='string',
        accessPolicy='string',
        forceUpdate=True|False
    )
    
  :type destinationName: string
  :param destinationName: **[REQUIRED]** 

    A name for an existing destination.

    

  
  :type accessPolicy: string
  :param accessPolicy: **[REQUIRED]** 

    An IAM policy document that authorizes cross-account users to deliver their log events to the associated destination. This can be up to 5120 bytes.

    

  
  :type forceUpdate: boolean
  :param forceUpdate: 

    Specify true if you are updating an existing destination policy to grant permission to an organization ID instead of granting permission to individual Amazon Web Services accounts. Before you update a destination policy this way, you must first update the subscription filters in the accounts that send logs to this destination. If you do not, the subscription filters might stop working. By specifying ``true`` for ``forceUpdate``, you are affirming that you have already updated the subscription filters. For more information, see `Updating an existing cross-account subscription <https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/Cross-Account-Log_Subscription-Update.html>`__

     

    If you omit this parameter, the default of ``false`` is used.
