PUT (Upsert)

{
   "upsert": "your-table",
   "id": 123,
   "info": {
      "field1": "value1",
      "field2": "value2",
      "field3": "value3",
      ...
   }
}

• The id attribute should be present. You cannot mass update.
• The values should be the same as a SQL's update on your table, so lookup fields' value should be an ID.
• If the given ID doesn't exist, a new row will be created. For creation, consider passing the required fields with the desired values.
