Retrieves the specified [RuleGroup](API_RuleGroup.md).
## Request Syntax
```
{
"ARN": "string",
"Id": "string",
"Name": "string",
"Scope": "string"
}
```
## Request Parameters
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.
** [ARN](#API_GetRuleGroup_RequestSyntax) **
The Amazon Resource Name (ARN) of the entity.
Type: String
Length Constraints: Minimum length of 20. Maximum length of 2048.
Pattern: `.*\S.*`
Required: No
** [Id](#API_GetRuleGroup_RequestSyntax) **
A unique identifier for the rule group. 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}$`
Required: No
** [Name](#API_GetRuleGroup_RequestSyntax) **
The name of the rule group. You cannot change the name of a rule group after you create it.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 128.
Pattern: `^[\w\-]+$`
Required: No
** [Scope](#API_GetRuleGroup_RequestSyntax) **
Specifies whether this is for a global resource type, such as a Amazon CloudFront distribution. For an AWS Amplify application, use `CLOUDFRONT`.
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: No

## 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](#API_GetRuleGroup_ResponseSyntax) **
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}$`
** [RuleGroup](#API_GetRuleGroup_ResponseSyntax) **
Type: [RuleGroup](API_RuleGroup.md) object
## Errors
For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).
** WAFInternalErrorException **
Your request is valid, but AWS WAF couldn’t perform the operation because of a system problem. Retry your request.
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 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
** 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
