# Tag management

You can manage your resource Tags via the following endpoints:

* List all tags: [`GET /v3/flexMetal/tags`](https://docs.i3d.net/api/api_general#get-v3-flexmetal-tags)
  * This will display all your tags with corresponding server count per tag.
* Remove a tag: [`DELETE /v3/flexMetal/tags/{tag}`](https://docs.i3d.net/api/api_general#delete-v3-flexmetal-tags-tag)
  * The tag will be removed from the system and will be removed from all servers that have the associated tag.
* Rename a tag: [`PATCH /v3/flexMetal/tags/{tag}`](https://docs.i3d.net/api/api_general#put-v3-flexmetal-tags-tag)
  * This will rename the tag. Note that this renames the tag for all associated servers as well.
  * The request body must be: `{ "tag": "my_renamed_tag" }`
* Add a tag to a server: `POST /v3/flexMetal/servers/{uuid}/tag/{tag}`
* Remove a tag from a server: `DELETE /v3/flexMetal/servers/{uuid}/tag/{tag}`

{% hint style="info" %}
