The payload of a PATCH should contain "instructions describing how a resource currently residing on the origin server should be modified to produce a new version". All information should be passed in the payload and not in query-params.

For instance you could send:

PATCH /foo

[
  { 
    "op": "remove",
    "path": "/tags/0" 
  }
]

Path /tags/0 points to the first element of the array. The remaining elements should be shifted to the left.

See the JSON Patch draft for more details.
