# TagResource
<a name="API_TagResource"></a>

Associates the specified tags to a resource with the specified `resourceArn`. If existing tags on a resource aren't specified in the request parameters, they aren't changed. When a resource is deleted, the tags that are associated with that resource are deleted as well. AWS Batch resources that support tags are compute environments, jobs, job definitions, job queues, and scheduling policies. ARNs for child jobs of array and multi-node parallel (MNP) jobs aren't supported.

## Response Syntax
<a name="API_TagResource_ResponseSyntax"></a>

```
HTTP/1.1 200
```

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

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

## Errors
<a name="API_TagResource_Errors"></a>

 ** ClientException **   
These errors are usually caused by a client action. One example cause is using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Another cause is specifying an identifier that's not valid.  
HTTP Status Code: 400

 ** ServerException **   
These errors are usually caused by a server issue.  
HTTP Status Code: 500

## Examples
<a name="API_TagResource_Examples"></a>

In the following example or examples, the Authorization header contents (` [authorization-params] `) must be replaced with an AWS Signature Version 4 signature. For more information about creating these signatures, see [Signature Version 4 Signing Process](https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html) in the * AWS General Reference*.

You only need to learn how to sign HTTP requests if you intend to manually create them. When you use the [AWS Command Line Interface (AWS CLI)](http://aws.amazon.com/cli/) or one of the [AWS SDKs](http://aws.amazon.com/tools/) to make requests to AWS, these tools automatically sign the requests for you with the access key that you specify when you configure the tools. When you use these tools, you don't need to learn how to sign requests yourself.

### Example
<a name="API_TagResource_Example_1"></a>

This example adds a tag to the job definition with an ARN of "*arn:aws:batch:us-east-1:123456789012:job-definition/sleep30:1*".
