Updates the specified RuleGroup.
This operation completely replaces the mutable specifications that you already have
for the rule group with the ones that you provide to this call.
To modify a rule group, do the following:
Retrieve it by calling GetRuleGroup
Update its settings as needed
Provide the complete rule group specification to this call
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.
Temporary inconsistencies during updates
When you create or change a web ACL or other WAF resources, the changes take a small amount of time to propagate to all areas where the resources are stored. The propagation time can be from a few seconds to a number of minutes.
The following are examples of the temporary inconsistencies that you might notice during change propagation:
After you create a web ACL, if you try to associate it with a resource, you might get an exception indicating that the web ACL is unavailable.
After you add a rule group to a web ACL, the new rule group rules might be in effect in one area where the web ACL is used and not in another.
After you change a rule action setting, you might see the old action in some places and the new action in others.
After you add an IP address to an IP set that is in use in a blocking rule, the new address might be blocked in one area while still allowed in another.
For .NET Core this operation is only available in asynchronous form. Please refer to UpdateRuleGroupAsync.

| Exception | Condition |
|---|---|
| WAFConfigurationWarningException | The operation failed because you are inspecting the web request body, headers, or cookies without specifying how to handle oversize components. Rules that inspect the body must either provide an OversizeHandling configuration or they must be preceded by a SizeConstraintStatement that blocks the body content from being too large. Rules that inspect the headers or cookies must provide an OversizeHandling configuration. Provide the handling configuration and retry your operation. Alternately, you can suppress this warning by adding the following tag to the resource that you provide to this operation: Tag (key:WAF:OversizeFieldsHandlingConstraintOptOut, value:true). |
| WAFDuplicateItemException | WAF couldn’t perform the operation because the resource that you tried to save is a duplicate of an existing one. |
| WAFInternalErrorException | Your request is valid, but WAF couldn’t perform the operation because of a system problem. Retry your request. |
| WAFInvalidOperationException | The operation isn't valid. |
| WAFInvalidParameterException | The operation failed because WAF didn't recognize a parameter in the request. For example: You specified a parameter name or value that isn't valid. Your nested statement isn't valid. You might have tried to nest a statement that can’t be nested. You tried to update a WebACL with a DefaultAction that isn't among the types available at DefaultAction. Your request references an ARN that is malformed, or corresponds to a resource with which a web ACL can't be associated. |
| WAFLimitsExceededException | WAF couldn’t perform the operation because you exceeded your resource limit. For example, the maximum number of WebACL objects that you can create for an Amazon Web Services account. For more information, see WAF quotas in the WAF Developer Guide. |
| WAFNonexistentItemException | WAF couldn’t perform the operation because your resource doesn't exist. If you've just created a resource that you're using in this operation, you might just need to wait a few minutes. It can take from a few seconds to a number of minutes for changes to propagate. |
| WAFOptimisticLockException | WAF couldn’t save your changes because you tried to update or delete a resource that has changed since you last retrieved it. Get the resource again, make any changes you need to make to the new copy, and retry your operation. |
| WAFSubscriptionNotFoundException | You tried to use a managed rule group that's available by subscription, but you aren't subscribed to it yet. |
| WAFUnavailableEntityException | WAF couldn’t retrieve a resource that you specified for this operation. If you've just created a resource that you're using in this operation, you might just need to wait a few minutes. It can take from a few seconds to a number of minutes for changes to propagate. Verify the resource specifications in your request parameters and then retry the operation. |
