The last thing you would most likely want to do with tags is to delete them. We can do that with the following DELETE call: http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/{id}/tags/{tagId}
The Node Identifier for the folder or file node to have its tag deleted is specified with the {id} parameter. And the tag we want to delete is specified with the {tagId} parameter.
As an example we will delete the tag that we just added to the file, which has the a427120f-a679-43e6-bcc5-4b0be1f91ea3 Identifier:
$ curl -X DELETE -H 'Accept: application/json' -H 'Authorization: Basic VElDS0VUXzA4ZWI3ZTJlMmMxNzk2NGNhNTFmMGYzMzE4NmNjMmZjOWQ1NmQ1OTM=' 'http://localhost:8080/alfresco/api/-default-/public/alfresco/versions/1/nodes/7279b5c5-da55-4e98-8b12-72d33b90c810/tags/a427120f-a679-43e6-bcc5-4b0be1f91ea3' | jq
