}
```

## Request Parameters
<a name="API_route53resolver_ListResolverConfigs_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.

 ** [MaxResults](#API_route53resolver_ListResolverConfigs_RequestSyntax) **   <a name="Route53Resolver-route53resolver_ListResolverConfigs-request-MaxResults"></a>
The maximum number of Resolver configurations that you want to return in the response to a `ListResolverConfigs` request. If you don't specify a value for `MaxResults`, up to 100 Resolver configurations are returned.  
Type: Integer  
Valid Range: Minimum value of 5. Maximum value of 100.  
Required: No

 ** [NextToken](#API_route53resolver_ListResolverConfigs_RequestSyntax) **   <a name="Route53Resolver-route53resolver_ListResolverConfigs-request-NextToken"></a>
(Optional) If the current AWS account has more than `MaxResults` Resolver configurations, use `NextToken` to get the second and subsequent pages of results.  
For the first `ListResolverConfigs` request, omit this value.  
For the second and subsequent requests, get the value of `NextToken` from the previous response and specify that value for `NextToken` in the request.  
Type: String  
Required: No

## Response Syntax

{
   "NextToken": "string",

      { 
         "AutodefinedReverse": "string",
         "Id": "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.
