# ListTags
<a name="API_ListTags"></a>

Lists all tags currently on a named resource. A tag is a key-value pair where the key and value are case-sensitive. You can use tags to categorize and track your MemoryDB resources. For more information, see [Tagging your MemoryDB resources](https://docs.amazonaws.cn/MemoryDB/latest/devguide/Tagging-Resources.html).

When you add or remove tags from multi region clusters, you might not immediately see the latest effective tags in the ListTags API response due to it being eventually consistent specifically for multi region clusters. For more information, see [Tagging your MemoryDB resources](https://docs.amazonaws.cn/MemoryDB/latest/devguide/Tagging-Resources.html).
