CreateRuleGroup - AWS WAFV2


Creates a RuleGroup per the specifications provided.

A rule group defines a collection of rules to inspect and control web requests that you can use in a WebACL. When you create a rule group, you define an immutable capacity limit. If you update a rule group, you must stay within the capacity. This allows others to reuse the rule group with confidence in its capacity requirements.

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.


The web ACL capacity units (WCUs) required for this rule group.

When you create your own rule group, you define this, and you cannot change it after creation. When you add or modify the rules in a rule group, AWS WAF enforces this limit. You can check the capacity for a set of rules using CheckCapacity.

AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

Type: Long

Valid Range: Minimum value of 1.

Required: Yes


A map of custom response keys and content bodies. When you create a rule with a block action, you can send a custom response to the web request. You define these for the rule group, and then use them in the rules that you define in the rule group.

For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide.

For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide.

Type: String to CustomResponseBody object map

Map Entries: Maximum number of items.

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

Key Pattern: ^[\w\-]+$

Required: No


A description of the rule group that helps with identification.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 256.

Pattern: ^[\w+=:#@/\-,\.][\w+=:#@/\-,\.\s]+[\w+=:#@/\-,\.]$

Required: No


The name of the rule group. You cannot change the name of a rule group after you create it.

Type: String

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

Pattern: ^[\w\-]+$

Required: Yes


The Rule statements used to identify the web requests that you want to allow, block, or count. Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

Type: Array of Rule objects

Required: No


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

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


Required: Yes


An array of key:value pairs to associate with the resource.

Type: Array of Tag objects

Array Members: Minimum number of 1 item.

Required: No


Defines and enables Amazon CloudWatch metrics and web request sample collection.

Response Syntax

{ "Summary": { "ARN": "string", "Description": "string", "Id": "string", "LockToken": "string", "Name": "string" } }

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.


High-level information about a RuleGroup, returned by operations like create and list. This provides information like the ID, that you can use to retrieve and manage a RuleGroup, and the ARN, that you provide to the RuleGroupReferenceStatement to use the rule group in a Rule.

Type: RuleGroupSummary object

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 you exceeded your resource limit. For example, the maximum number of WebACL objects that you can create for an AWS account. For more information, see AWS WAF quotas in the AWS WAF Developer Guide.

HTTP Status Code: 400


AWS WAF couldn’t perform the operation because your resource doesn’t exist.

HTTP Status Code: 400


AWS WAF couldn’t save your changes because you tried to update or delete a resource that has changed since you last retrieved it. Get the resource again, make any changes you need to make to the new copy, and retry your operation.
