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.


A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException. If this happens, perform another get, and use the new token returned by that operation.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 36.

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


The managed rule set that you requested.

Type: ManagedRuleSet object

Your request is valid, but AWS WAF couldn’t perform the operation because of a system problem. Retry your request.

HTTP Status Code: 500


The operation isn't valid.

HTTP Status Code: 400


The operation failed because AWS WAF didn't recognize a parameter in the request. For example:

  • You specified a parameter name or value that isn't valid.

  • Your nested statement isn't valid. You might have tried to nest a statement that can’t be nested.

  • You tried to update a WebACL with a DefaultAction that isn't among the types available at DefaultAction.

  • Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL can't be associated.

HTTP Status Code: 400


AWS WAF couldn’t perform the operation because your resource doesn't exist. If you've just created a resource that you're using in this operation, you might just need to wait a few minutes. It can take from a few seconds to a number of minutes for changes to propagate.

HTTP Status Code: 400
