Inserts or deletes Predicate objects in a
object identifies a predicate, such as a ByteMatchSet or an IPSet, that
specifies the web requests that you want to allow, block, or count. If you add more
than one predicate to a
Rule, a request must match all of the specifications
to be allowed, blocked, or counted. For example, suppose you add the following to
ByteMatchSet that matches the value
BadBot in the
IPSet that matches the IP address
You then add the
Rule to a
WebACL and specify that you want
to block requests that satisfy the
Rule. For a request to be blocked,
User-Agent header in the request must contain the value
BadBotand the request must originate from the IP address 192.0.2.44.
To create and configure a
Rule, perform the following steps:
Create and update the predicates that you want to include in the
Rule. See CreateRule.
GetChangeToken to get the change token that you provide in the
parameter of an UpdateRule request.
UpdateRule request to add predicates to the
Create and update a
WebACL that contains the
Rule. See CreateWebACL.
If you want to replace one
IPSet with another,
you delete the existing one and add the new one.

For .NET Core and PCL this operation is only available in asynchronous form. Please refer to UpdateRuleAsync.
public virtual UpdateRuleResponse UpdateRule( String ruleId, List<RuleUpdate> updates, String changeToken )
The RuleId of the Rule that you want to update. RuleId is returned by CreateRule and by ListRules.
An array of RuleUpdate objects that you want to insert into or delete from a Rule. For more information, see the applicable data types: RuleUpdate: Contains Action and PredicatePredicate: Contains DataId, Negated, and TypeFieldToMatch: Contains Data and Type
The value returned by the most recent call to GetChangeToken.
|WAFInternalErrorException||The operation failed because of a system problem, even though the request was valid. Retry your request.|
|WAFInvalidAccountException||The operation failed because you tried to create, update, or delete an object by using an invalid account identifier.|
|WAFInvalidOperationException||The operation failed because there was nothing to do. For example: You tried to remove a Rule from a WebACL, but the Rule isn't in the specified WebACL. You tried to remove an IP address from an IPSet, but the IP address isn't in the specified IPSet. You tried to remove a ByteMatchTuple from a ByteMatchSet, but the ByteMatchTuple isn't in the specified WebACL. You tried to add a Rule to a WebACL, but the Rule already exists in the specified WebACL. You tried to add an IP address to an IPSet, but the IP address already exists in the specified IPSet. You tried to add a ByteMatchTuple to a ByteMatchSet, but the ByteMatchTuple already exists in the specified WebACL.|
|WAFInvalidParameterException||The operation failed because AWS WAF didn't recognize a parameter in the request. For example: You specified an invalid parameter name. You specified an invalid value. You tried to update an object (ByteMatchSet, IPSet, Rule, or WebACL) using an action other than INSERT or DELETE. You tried to create a WebACL with a DefaultActionType other than ALLOW, BLOCK, or COUNT. You tried to create a RateBasedRule with a RateKey value other than IP. You tried to update a WebACL with a WafActionType other than ALLOW, BLOCK, or COUNT. You tried to update a ByteMatchSet with a FieldToMatchType other than HEADER, METHOD, QUERY_STRING, URI, or BODY. You tried to update a ByteMatchSet with a Field of HEADER but no value for Data. Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL cannot be associated.|
|WAFLimitsExceededException||The operation exceeds a resource limit, for example, the maximum number of WebACL objects that you can create for an AWS account. For more information, see Limits in the AWS WAF Developer Guide.|
|WAFNonexistentContainerException||The operation failed because you tried to add an object to or delete an object from another object that doesn't exist. For example: You tried to add a Rule to or delete a Rule from a WebACL that doesn't exist. You tried to add a ByteMatchSet to or delete a ByteMatchSet from a Rule that doesn't exist. You tried to add an IP address to or delete an IP address from an IPSet that doesn't exist. You tried to add a ByteMatchTuple to or delete a ByteMatchTuple from a ByteMatchSet that doesn't exist.|
|WAFNonexistentItemException||The operation failed because the referenced object doesn't exist.|
|WAFReferencedItemException||The operation failed because you tried to delete an object that is still in use. For example: You tried to delete a ByteMatchSet that is still referenced by a Rule. You tried to delete a Rule that is still referenced by a WebACL.|
|WAFStaleDataException||The operation failed because you tried to create, update, or delete an object by using a change token that has already been used.|
