Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

FirewallPolicy

The policy for the specified firewall policy.

Type: FirewallPolicy object

FirewallPolicyResponse

The high-level properties of a firewall policy. This, along with the FirewallPolicy, define the policy. You can retrieve all objects for a firewall policy by calling DescribeFirewallPolicy.

Type: FirewallPolicyResponse object

UpdateToken

A token used for optimistic locking. Network Firewall returns a token to your requests that access the firewall policy. The token marks the state of the policy resource at the time of the request.

To make changes to the policy, you provide the token in your request. Network Firewall uses the token to ensure that the policy hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException. If this happens, retrieve the firewall policy again to get a current copy of it with current token. Reapply your changes as needed, then try the operation again using the new token.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Pattern: ^([0-9a-f]{8})-([0-9a-f]{4}-){3}([0-9a-f]{12})$
