TagResource - AWS Billing and Cost Management

TagResource

An API operation for adding one or more tags (key-value pairs) to a resource.

You can use the TagResource operation with a resource that already has tags. If you specify a new tag key for the resource, this tag is appended to the list of tags associated with the resource. If you specify a tag key that is already associated with the resource, the new tag value you specify replaces the previous value for that tag.

Although the maximum number of array members is 200, user-tag maximum is 50. The remaining are reserved for AWS use.
