# CreateRuleGroup
<a name="API_CreateRuleGroup"></a>

Creates a [RuleGroup](API_RuleGroup.md) 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](API_WebACL.md). 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
<a name="API_CreateRuleGroup_RequestParameters"></a>

For information about the parameters that are common to all actions, see [Common Parameters](CommonParameters.md).

The request accepts the following data in JSON format.

 ** [Capacity](#API_CreateRuleGroup_RequestSyntax) **   <a name="WAF-CreateRuleGroup-request-Capacity"></a>
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](API_CheckCapacity.md).  
 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. For more information, see [AWS WAF web ACL capacity units (WCU)](https://docs.aws.amazon.com/waf/latest/developerguide/aws-waf-capacity-units.html) in the * AWS WAF Developer Guide*.   
Type: Long  
Valid Range: Minimum value of 1.  
Required: Yes

 ** [CustomResponseBodies](#API_CreateRuleGroup_RequestSyntax) **   <a name="WAF-CreateRuleGroup-request-CustomResponseBodies"></a>
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](https://docs.aws.amazon.com/waf/latest/developerguide/waf-custom-request-response.html) 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](https://docs.aws.amazon.com/waf/latest/developerguide/limits.html) in the * AWS WAF Developer Guide*.   
Type: String to [CustomResponseBody](API_CustomResponseBody.md) object map  
Map Entries: Maximum number of items.  
Key Length Constraints: Minimum length of 1. Maximum length of 128.  
Key Pattern: `^[\w\-]+$`   
Required: No

 ** [Description](#API_CreateRuleGroup_RequestSyntax) **   <a name="WAF-CreateRuleGroup-request-Description"></a>
A description of the rule group that helps with identification.   
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.

## Errors
<a name="API_CreateRuleGroup_Errors"></a>

For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).

 ** WAFDuplicateItemException **   
 AWS WAF couldn’t perform the operation because the resource that you tried to save is a duplicate of an existing one.  
HTTP Status Code: 400

+ 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](API_DefaultAction.md).
+ Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL can't be associated.  
 ** Field **   
The settings where the invalid parameter was found.   
 ** Parameter **   
The invalid parameter that resulted in the exception.   
 ** Reason **   
Additional information about the exception.
HTTP Status Code: 400

 ** WAFLimitsExceededException **   
 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](https://docs.aws.amazon.com/waf/latest/developerguide/limits.html) in the * AWS WAF Developer Guide*.    
 ** SourceType **   
Source type for the exception. 
HTTP Status Code: 400

 ** WAFNonexistentItemException **   
 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

 ** WAFOptimisticLockException **   
 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.   
HTTP Status Code: 400

 ** WAFSubscriptionNotFoundException **   
You tried to use a managed rule group that's available by subscription, but you aren't subscribed to it yet.
