# CreateTags
<a name="API_CreateTags"></a>

**Note**  
DEPRECATED - `CreateTags` is deprecated and not maintained. To create tags for EFS resources, use the [TagResource](API_TagResource.md) API action.

Creates or overwrites tags associated with a file system. Each tag is a key-value pair. If a tag key specified in the request already exists on the file system, this operation overwrites its value with the value provided in the request. If you add the `Name` tag to your file system, Amazon EFS returns it in the response to the [DescribeFileSystems](API_DescribeFileSystems.md) operation. 

This operation requires permission for the `elasticfilesystem:CreateTags` action.

 ** BadRequest **   
Returned if the request is malformed or contains an error such as an invalid parameter value or a missing required parameter.    
 ** ErrorCode **   
The error code is a string that uniquely identifies an error condition. It is meant to be read and understood by programs that detect and handle errors by type.   
 ** Message **   
The error message contains a generic description of the error condition in English. It is intended for a human audience. Simple programs display the message directly to the end user if they encounter an error condition they don't know how or don't care to handle. Sophisticated programs with more exhaustive error handling and proper internationalization are more likely to ignore the error message.
HTTP Status Code: 400
