WAF
This is the latest version of the WAF API, released in November, 2019.
The names of the entities that you use to access this API, like endpoints and namespaces, all have the versioning information added, like "V2" or "v2", to distinguish from the prior version. We recommend migrating your resources to this version, because it has a number of significant improvements.
If you used WAF prior to this release, you can't use this WAFV2 API to access any WAF resources that you created before. You can access your old rules, web ACLs, and other WAF resources only through the WAF Classic APIs. The WAF Classic APIs have retained the prior names, endpoints, and namespaces.
For information, including how to migrate your WAF resources to this version, see the WAF Developer Guide.
WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to an Amazon CloudFront distribution, Amazon API Gateway REST API, Application Load Balancer, AppSync GraphQL API, Amazon Cognito user pool, or App Runner service. WAF also lets you control access to your content, to protect the Amazon Web Services resource that WAF is monitoring. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, the protected resource responds to requests with either the requested content, an HTTP 403 status code (Forbidden), or with a custom response.
This API guide is for developers who need detailed information about WAF API actions, data types, and errors. For detailed information about WAF features and guidance for configuring and using WAF, see the WAF Developer Guide.
You can make calls using the endpoints listed in WAF endpoints and quotas.
For regional applications, you can use any of the endpoints in the list. A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, an AppSync GraphQL API, an Amazon Cognito user pool, or an App Runner service.
For Amazon CloudFront applications, you must use the API endpoint listed for US East (N. Virginia): us-east-1.
Alternatively, you can use one of the Amazon Web Services SDKs to access an API that's tailored to the programming language or platform that you're using. For more information, see Amazon Web Services SDKs.
We currently provide two versions of the WAF API: this API and the prior versions, the classic WAF APIs. This new API provides the same functionality as the older versions, with the following major improvements:
You use one API for both global and regional applications. Where you need to distinguish the scope, you specify a
Scope
parameter and set it toCLOUDFRONT
orREGIONAL
.You can define a web ACL or rule group with a single call, and update it with a single call. You define all rule specifications in JSON format, and pass them to your rule group or web ACL calls.
The limits WAF places on the use of rules more closely reflects the cost of running each type of rule. Rule groups include capacity settings, so you know the maximum cost of a rule group when you use it.

Associates a web ACL with a regional application resource, to protect the resource.
A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, an AppSync GraphQL API, an Amazon Cognito user pool, or an App Runner service.
For Amazon CloudFront, don't use this call. Instead, use your CloudFront
distribution configuration. To associate a web ACL, in the CloudFront call
UpdateDistribution
, set the web ACL ID to the Amazon Resource Name (ARN) of
the web ACL. For information, see
UpdateDistribution
in the Amazon CloudFront Developer Guide.
When you make changes to web ACLs or web ACL components, like rules and rule groups, WAF propagates the changes everywhere that the web ACL and its components are stored and used. Your changes are applied within seconds, but there might be a brief period of inconsistency when the changes have arrived in some places and not in others. So, for example, if you change a rule action setting, the action might be the old action in one area and the new action in another area. Or if you add an IP address to an IP set used in a blocking rule, the new address might briefly be blocked in one area while still allowed in another. This temporary inconsistency can occur when you first associate a web ACL with an Amazon Web Services resource and when you change a web ACL that is already associated with a resource. Generally, any inconsistencies of this type last only a few seconds.
Returns the web ACL capacity unit (WCU) requirements for a specified scope and set of rules.
You can use this to check the capacity requirements for the rules you want to
use in a RuleGroup
or WebACL
.
WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. 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 WAF web ACL capacity units (WCU) in the WAF Developer Guide.
Creates an API key for use in the integration of the CAPTCHA API in your JavaScript client applications.
The integration lets you customize the placement and characteristics of the CAPTCHA puzzle for your end users. For more information about the CAPTCHA JavaScript integration, see WAF client application integration in the WAF Developer Guide.
The CAPTCHA API requires a key that authorizes CAPTCHA use from the client application domain. You can use a single key for up to 5 domains. After you generate a key, you can copy it for use in your JavaScript integration.
Creates an IPSet
, which you use to identify web requests that originate from
specific IP addresses or ranges of IP addresses.
For example, if you're receiving a lot of requests from a ranges of IP addresses, you can configure WAF to block them using an IPSet that lists those IP addresses.
Creates a RegexPatternSet
, which you reference in a
RegexPatternSetReferenceStatement
, to have WAF inspect a web request component
for the specified patterns.
Creates a RuleGroup
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
. 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.
Creates a WebACL
per the specifications provided.
A web ACL defines a collection of rules to use to inspect and control web
requests. Each rule has an action defined (allow, block, or count) for requests
that match the statement of the rule. In the web ACL, you assign a default
action to take (allow, block) for any request that does not match any of the
rules. The rules in a web ACL can be a combination of the types Rule
,
RuleGroup
, and managed rule group. You can associate a web ACL with one or
more Amazon Web Services resources to protect. The resources can be an Amazon
CloudFront distribution, an Amazon API Gateway REST API, an Application Load
Balancer, an AppSync GraphQL API, an Amazon Cognito user pool, or an App Runner
service.
Deletes all rule groups that are managed by Firewall Manager for the specified web ACL.
You can only use this if ManagedByFirewallManager
is false in the specified
WebACL
.
Deletes the specified IPSet
.
Deletes the LoggingConfiguration
from the specified web ACL.
Permanently deletes an IAM policy from the specified rule group.
You must be the owner of the rule group to perform this operation.
Deletes the specified RegexPatternSet
.
Deletes the specified RuleGroup
.
Deletes the specified WebACL
.
You can only use this if ManagedByFirewallManager
is false in the specified
WebACL
.
Before deleting any web ACL, first disassociate it from all resources.
To retrieve a list of the resources that are associated with a web ACL, use the following calls:
For regional resources, call `ListResourcesForWebACL`.
For Amazon CloudFront distributions, use the CloudFront
call ListDistributionsByWebACLId
. For information, see
ListDistributionsByWebACLId in the Amazon CloudFront API Reference.
To disassociate a resource from a web ACL, use the following calls:
For regional resources, call `DisassociateWebACL`.
For Amazon CloudFront distributions, provide an empty
web ACL ID in the CloudFront call UpdateDistribution
. For information, see
UpdateDistribution
in the Amazon CloudFront API Reference.
Provides high-level information for a managed rule group, including descriptions of the rules.
Disassociates the specified regional application resource from any existing web ACL association.
A resource can have at most one web ACL association. A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, an AppSync GraphQL API, an Amazon Cognito user pool, or an App Runner service.
For Amazon CloudFront, don't use this call. Instead, use your CloudFront
distribution configuration. To disassociate a web ACL, provide an empty web ACL
ID in the CloudFront call UpdateDistribution
. For information, see
UpdateDistribution
in the Amazon CloudFront API Reference.
Generates a presigned download URL for the specified release of the mobile SDK.

You must be the owner of the rule group to perform this operation.
get_rate_based_statement_managed_keys(client, input, options \\ [])
View SourceRetrieves the keys that are currently blocked by a rate-based rule instance.
The maximum number of managed keys that can be blocked for a single rate-based rule instance is 10,000. If more than 10,000 addresses exceed the rate limit, those with the highest rates are blocked.
For a rate-based rule that you've defined inside a rule group, provide the name of the rule group reference statement in your request, in addition to the rate-based rule name and the web ACL name.
WAF monitors web requests and manages keys independently for each unique combination of web ACL, optional rule group, and rate-based rule. For example, if you define a rate-based rule inside a rule group, and then use the rule group in a web ACL, WAF monitors web requests and manages keys for that web ACL, rule group reference statement, and rate-based rule instance. If you use the same rule group in a second web ACL, WAF monitors web requests and manages keys for this second usage completely independent of your first.
Retrieves the specified RegexPatternSet
.
Retrieves the specified RuleGroup
.
Gets detailed information about a specified number of requests--a sample--that WAF randomly selects from among the first 5,000 requests that your Amazon Web Services resource received during a time range that you choose.
You can specify a sample size of up to 500 requests, and you can specify any time range in the previous three hours.
GetSampledRequests
returns a time range, which is usually the time range that
you specified. However, if your resource (such as a CloudFront distribution)
received 5,000 requests before the specified time range elapsed,
GetSampledRequests
returns an updated time range. This new time range
indicates the actual period during which WAF selected the requests in the
sample.

To modify an existing logging configuration, do the following:
Retrieve it by calling GetLoggingConfiguration
Update its settings as needed
Provide the complete logging configuration specification to this call
You can define one logging destination per web ACL.
You can access information about the traffic that WAF inspects using the following steps:
- Create your logging destination. You can use an Amazon CloudWatch Logs log group, an Amazon Simple Storage Service (Amazon S3) bucket, or an Amazon Kinesis Data Firehose.
The name that you give the destination must start with aws-waf-logs-
.
Depending on the type of destination, you might need to configure additional
settings or permissions.
For configuration requirements and pricing information for each destination type, see Logging web ACL traffic in the WAF Developer Guide.
- Associate your logging destination to your web ACL using a
PutLoggingConfiguration
request.
When you successfully enable logging using a PutLoggingConfiguration
request,
WAF creates an additional role or policy that is required to write logs to the
logging destination. For an Amazon CloudWatch Logs log group, WAF creates a
resource policy on the log group. For an Amazon S3 bucket, WAF creates a bucket
policy. For an Amazon Kinesis Data Firehose, WAF creates a service-linked role.
For additional information about web ACL logging, see Logging web ACL traffic information in the WAF Developer Guide.
