# Tag a Firehose stream
<a name="firehose-tagging"></a>

You can assign your own metadata to Firehose streams that you create in Amazon Data Firehose in the form of *tags*. A tag is a key-value pair that you define for a stream. Using tags is a simple yet powerful way to manage AWS resources and organize data, including billing data. 

You can specify tags when you invoke [CreateDeliveryStream](https://docs.aws.amazon.com/firehose/latest/APIReference/API_CreateDeliveryStream.html) to create a new Firehose stream. For existing Firehose streams, you can add, list, and remove tags using the following three operations: 
+ [TagDeliveryStream](https://docs.aws.amazon.com/firehose/latest/APIReference/API_TagDeliveryStream.html)
+ [ListTagsForDeliveryStream](https://docs.aws.amazon.com/firehose/latest/APIReference/API_ListTagsForDeliveryStream.html)
+ [UntagDeliveryStream](https://docs.aws.amazon.com/firehose/latest/APIReference/API_UntagDeliveryStream.html)
