Request Syntax

{ "Id": "string", "Name": "string", "Scope": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Id

The unique identifier for the Web ACL. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

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}$

Required: Yes

Name

The name of the Web ACL. You cannot change the name of a Web ACL after you create it.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 128.

Pattern: ^[\w\-]+$

Required: Yes

Scope

Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB) or an API Gateway stage.

To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

  • CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1.

  • API and SDKs - For all calls, use the Region endpoint us-east-1.

Type: String

Valid Values: CLOUDFRONT | REGIONAL

Required: Yes

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.

LockToken

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}$

WebACL

The Web ACL specification. You can modify the settings in this Web ACL and use it to update this Web ACL or create a new one.

Type: WebACL object

HTTP Status Code: 500

WAFInvalidOperationException

The operation isn't valid.

HTTP Status Code: 400

WAFInvalidParameterException

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

  • You specified an invalid parameter name or value.

  • 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 cannot be associated.

HTTP Status Code: 400
