## Request Parameters
<a name="API_CreateAnomalyMonitor_RequestParameters"></a>

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.

 ** [AnomalyMonitor](#API_CreateAnomalyMonitor_RequestSyntax) **   <a name="awscostmanagement-CreateAnomalyMonitor-request-AnomalyMonitor"></a>
The cost anomaly detection monitor object that you want to create.  
Type: [AnomalyMonitor](API_AnomalyMonitor.md) object  
Required: Yes

 ** [ResourceTags](#API_CreateAnomalyMonitor_RequestSyntax) **   <a name="awscostmanagement-CreateAnomalyMonitor-request-ResourceTags"></a>
An optional list of tags to associate with the specified [https://docs.aws.amazon.com/aws-cost-management/latest/APIReference/API_AnomalyMonitor.html](https://docs.aws.amazon.com/aws-cost-management/latest/APIReference/API_AnomalyMonitor.html). You can use resource tags to control access to your `monitor` using IAM policies.  
Each tag consists of a key and a value, and each key must be unique for the resource. The following restrictions apply to resource tags:  
+ Although the maximum number of array members is 200, you can assign a maximum of 50 user-tags to one resource. The remaining are reserved for AWS use
+ The maximum length of a key is 128 characters
+ The maximum length of a value is 256 characters
+ Keys and values can only contain alphanumeric characters, spaces, and any of the following: `_.:/=+@-` 
+ Keys and values are case sensitive
+ Keys and values are trimmed for any leading or trailing whitespaces
+ Don’t use `aws:` as a prefix for your keys. This prefix is reserved for AWS use
Type: Array of [ResourceTag](API_ResourceTag.md) objects  
Array Members: Minimum number of 0 items. Maximum number of 200 items.  
Required: No

## Response Elements
<a name="API_CreateAnomalyMonitor_ResponseElements"></a>

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

 ** [MonitorArn](#API_CreateAnomalyMonitor_ResponseSyntax) **   <a name="awscostmanagement-CreateAnomalyMonitor-response-MonitorArn"></a>
The unique identifier of your newly created cost anomaly detection monitor.  
Type: String  
Length Constraints: Minimum length of 0. Maximum length of 1024.  
Pattern: `[\S\s]*` 

## Errors
