## Request Syntax
<a name="API_ListRegexPatternSets_RequestSyntax"></a>

```
{
   "Limit": number,
   "NextMarker": "string",
   "Scope": "string"
}
```

## Request Parameters
<a name="API_ListRegexPatternSets_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.

 ** [Limit](#API_ListRegexPatternSets_RequestSyntax) **   <a name="WAF-ListRegexPatternSets-request-Limit"></a>
The maximum number of objects that you want AWS WAF to return for this request. If more objects are available, in the response, AWS WAF provides a `NextMarker` value that you can use in a subsequent call to get the next batch of objects.  
Type: Integer  
Valid Range: Minimum value of 1. Maximum value of 100.  
Required: No

 ** [NextMarker](#API_ListRegexPatternSets_RequestSyntax) **   <a name="WAF-ListRegexPatternSets-request-NextMarker"></a>
When you request a list of objects with a `Limit` setting, if the number of objects that are still available for retrieval exceeds the limit, AWS WAF returns a `NextMarker` value in the response. To retrieve the next batch of objects, provide the marker from the prior call in your next request.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `.*\S.*`   
Required: No

 ** [Scope](#API_ListRegexPatternSets_RequestSyntax) **   <a name="WAF-ListRegexPatternSets-request-Scope"></a>
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: Yes

## Response Elements
<a name="API_ListRegexPatternSets_ResponseElements"></a>

The following data is returned in JSON format by the service.

 ** [NextMarker](#API_ListRegexPatternSets_ResponseSyntax) **   <a name="WAF-ListRegexPatternSets-response-NextMarker"></a>
When you request a list of objects with a `Limit` setting, if the number of objects that are still available for retrieval exceeds the limit, AWS WAF returns a `NextMarker` value in the response. To retrieve the next batch of objects, provide the marker from the prior call in your next request.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `.*\S.*` 

 ** [RegexPatternSets](#API_ListRegexPatternSets_ResponseSyntax) **   <a name="WAF-ListRegexPatternSets-response-RegexPatternSets"></a>
Array of regex pattern sets. If you specified a `Limit` in your request, this might not be the full list.   
Type: Array of [RegexPatternSetSummary](API_RegexPatternSetSummary.md) objects

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

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.
