# UpdateAnomalySubscription


Updates an existing cost anomaly subscription. Specify the fields that you want to update. Omitted fields are unchanged.

**Note**  
The JSON below describes the generic construct for each type. See [Request Parameters](https://docs.aws.amazon.com/aws-cost-management/latest/APIReference/API_UpdateAnomalySubscription.html#API_UpdateAnomalySubscription_RequestParameters) for possible values as they apply to `AnomalySubscription`.

## Request Parameters


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.

 ** [Frequency](#API_UpdateAnomalySubscription_RequestSyntax) **   <a name="awscostmanagement-UpdateAnomalySubscription-request-Frequency"></a>
The update to the frequency value that subscribers receive notifications.   
Type: String  
Valid Values: `DAILY | IMMEDIATE | WEEKLY`   
Required: No

 ** [MonitorArnList](#API_UpdateAnomalySubscription_RequestSyntax) **   <a name="awscostmanagement-UpdateAnomalySubscription-request-MonitorArnList"></a>
A list of cost anomaly monitor ARNs.   
Type: Array of strings  
Length Constraints: Minimum length of 20. Maximum length of 2048.  
Pattern: `arn:aws[-a-z0-9]*:[a-z0-9]+:[-a-z0-9]*:[0-9]{12}:[-a-zA-Z0-9/:_]+`   
Required: No

 ** [Subscribers](#API_UpdateAnomalySubscription_RequestSyntax) **   <a name="awscostmanagement-UpdateAnomalySubscription-request-Subscribers"></a>
The update to the subscriber list.   
Type: Array of [Subscriber](API_Subscriber.md) objects  
Required: No

 ** [SubscriptionArn](#API_UpdateAnomalySubscription_RequestSyntax) **   <a name="awscostmanagement-UpdateAnomalySubscription-request-SubscriptionArn"></a>
A cost anomaly subscription Amazon Resource Name (ARN).   
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 1024.  
Pattern: `[\S\s]*`   
Required: Yes

 ** [SubscriptionName](#API_UpdateAnomalySubscription_RequestSyntax) **   <a name="awscostmanagement-UpdateAnomalySubscription-request-SubscriptionName"></a>
The new name of the subscription.   
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 1024.  
Pattern: `[\S\s]*`   
Required: No

 ** [Threshold](#API_UpdateAnomalySubscription_RequestSyntax) **   <a name="awscostmanagement-UpdateAnomalySubscription-request-Threshold"></a>
(deprecated)  
The update to the threshold value for receiving notifications.   
This field has been deprecated. To update a threshold, use ThresholdExpression. Continued use of Threshold will be treated as shorthand syntax for a ThresholdExpression.  
You can specify either Threshold or ThresholdExpression, but not both.  
Type: Double  
Valid Range: Minimum value of 0.0.  
Required: No

 ** [ThresholdExpression](#API_UpdateAnomalySubscription_RequestSyntax) **   <a name="awscostmanagement-UpdateAnomalySubscription-request-ThresholdExpression"></a>
The update to the [Expression](https://docs.aws.amazon.com/aws-cost-management/latest/APIReference/API_Expression.html) object used to specify the anomalies that you want to generate alerts for. This supports dimensions and nested expressions. The supported dimensions are `ANOMALY_TOTAL_IMPACT_ABSOLUTE` and `ANOMALY_TOTAL_IMPACT_PERCENTAGE`, corresponding to an anomaly’s TotalImpact and TotalImpactPercentage, respectively (see [Impact](https://docs.aws.amazon.com/aws-cost-management/latest/APIReference/API_Impact.html) for more details). The supported nested expression types are `AND` and `OR`. The match option `GREATER_THAN_OR_EQUAL` is required. Values must be numbers between 0 and 10,000,000,000 in string format.  
You can specify either Threshold or ThresholdExpression, but not both.  
The following are examples of valid ThresholdExpressions:  
+ Absolute threshold: `{ "Dimensions": { "Key": "ANOMALY_TOTAL_IMPACT_ABSOLUTE", "MatchOptions": [ "GREATER_THAN_OR_EQUAL" ], "Values": [ "100" ] } }` 
+ Percentage threshold: `{ "Dimensions": { "Key": "ANOMALY_TOTAL_IMPACT_PERCENTAGE", "MatchOptions": [ "GREATER_THAN_OR_EQUAL" ], "Values": [ "100" ] } }` 
+  `AND` two thresholds together: `{ "And": [ { "Dimensions": { "Key": "ANOMALY_TOTAL_IMPACT_ABSOLUTE", "MatchOptions": [ "GREATER_THAN_OR_EQUAL" ], "Values": [ "100" ] } }, { "Dimensions": { "Key": "ANOMALY_TOTAL_IMPACT_PERCENTAGE", "MatchOptions": [ "GREATER_THAN_OR_EQUAL" ], "Values": [ "100" ] } } ] }` 
+  `OR` two thresholds together: `{ "Or": [ { "Dimensions": { "Key": "ANOMALY_TOTAL_IMPACT_ABSOLUTE", "MatchOptions": [ "GREATER_THAN_OR_EQUAL" ], "Values": [ "100" ] } }, { "Dimensions": { "Key": "ANOMALY_TOTAL_IMPACT_PERCENTAGE", "MatchOptions": [ "GREATER_THAN_OR_EQUAL" ], "Values": [ "100" ] } } ] }` 
Type: [Expression](API_Expression.md) object  
Required: No

## Response Syntax


```
{
   "SubscriptionArn": "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.

A cost anomaly subscription ARN.   
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 1024.  
Pattern: `[\S\s]*`
