IAmazonWAFRegional.CreateWebACL Method (CreateWebACLRequest)

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates a WebACL, which contains the Rules that identify the CloudFront web requests that you want to allow, block, or count. AWS WAF evaluates Rules in order based on the value of Priority for each Rule.

You also specify a default action, either ALLOW or BLOCK. If a web request doesn't match any of the Rules in a WebACL, AWS WAF responds to the request with the default action.

To create and configure a WebACL, perform the following steps:

Create and update the ByteMatchSet objects and other predicates that you want to include in Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.
Create and update the Rules that you want to include in the WebACL. For more information, see CreateRule and UpdateRule.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateWebACL request.
Submit a CreateWebACL request.
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.
Submit an UpdateWebACL request to specify the Rules that you want to include in the WebACL, to specify the default action, and to associate the WebACL with a CloudFront distribution.

For more information about how to use the AWS WAF API, see the AWS WAF Developer Guide.

Note:

For .NET Core this operation is only available in asynchronous form. Please refer to CreateWebACLAsync.

Exceptions

Exception	Condition
WAFBadRequestException
WAFDisallowedNameException	The name specified is invalid.
WAFInternalErrorException	The operation failed because of a system problem, even though the request was valid. Retry your request.
WAFInvalidAccountException	The operation failed because you tried to create, update, or delete an object by using an invalid account identifier.
WAFInvalidParameterException	The operation failed because AWS WAF didn't recognize a parameter in the request. For example: You specified an invalid parameter name. You specified an invalid value. You tried to update an object (ByteMatchSet, IPSet, Rule, or WebACL) using an action other than INSERT or DELETE. You tried to create a WebACL with a DefaultActionType other than ALLOW, BLOCK, or COUNT. You tried to create a RateBasedRule with a RateKey value other than IP. You tried to update a WebACL with a WafActionType other than ALLOW, BLOCK, or COUNT. You tried to update a ByteMatchSet with a FieldToMatchType other than HEADER, METHOD, QUERY_STRING, URI, or BODY. You tried to update a ByteMatchSet with a Field of HEADER but no value for Data. Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL cannot be associated.
WAFLimitsExceededException	The operation exceeds a resource limit, for example, the maximum number of WebACL objects that you can create for an AWS account. For more information, see Limits in the AWS WAF Developer Guide.
WAFStaleDataException	The operation failed because you tried to create, update, or delete an object by using a change token that has already been used.
WAFTagOperationException
WAFTagOperationInternalErrorException
