curl -X POST
  -H "X-Parse-Application-Id: ${APPLICATION_ID}" \
  -H "X-Parse-REST-API-Key: ${REST_API_KEY}" \
  -H "Content-Type: application/json" \
  -d '{
        "requests": [
          {
            "method": "GET",
            "path": "/1/classes/GameScore",
            "body": {
              "where": {"age":11},
              "limit":1000
            }
          },
          {
            "method": "GET",
            "path": "/1/classes/GameScore2",
            "body": {
              "where": {"objectId":"Ed1nuqPvcm"}

          }
        ]

[{"success":{"results":[]}},{"success":{"results":[]}}]

Start at the /1/batch API entry point and trace how the existing batch request example is handled. Use the supplied curl request as the behavior to verify: GET requests should be accepted and return one success result per request, including the shown results structure.
