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.

Action

Optional additional filter for the rules to retrieve.

The action that DNS Firewall should take on a DNS query when it matches one of the domains in the rule's domain list:

ALLOW - Permit the request to go through.
ALERT - Permit the request to go through but send an alert to the logs.
BLOCK - Disallow the request. If this is specified, additional handling details are provided in the rule's BlockResponse setting.

Type: String

Valid Values: ALLOW | BLOCK | ALERT

Required: No

FirewallRuleGroupId

The unique identifier of the firewall rule group that you want to retrieve the rules for.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Required: Yes

MaxResults

The maximum number of objects that you want Resolver to return for this request. If more objects are available, in the response, Resolver provides a NextToken value that you can use in a subsequent call to get the next batch of objects.

If you don't specify a value for MaxResults, Resolver returns up to 100 objects.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 100.

Required: No

NextToken

For the first call to this list request, omit this value.

When you request a list of objects, Resolver returns at most the number of objects specified in MaxResults. If more objects are available for retrieval, Resolver returns a NextToken value in the response. To retrieve the next batch of objects, use the token that was returned for the prior request in your next request.

Type: String

Required: No

Priority

Optional additional filter for the rules to retrieve.

The setting that determines the processing order of the rules in a rule group. DNS Firewall processes the rules in a rule group by order of priority, starting from the lowest setting.

Type: Integer
