Hello,
There is no limit for JSON data.
JSON is similar to other data formats like XML - if you need to transmit more data, you just send more data. There's no inherent size limitation to the overall JSON request itself. Any limitation would be set by the server parsing the JSON request. (For instance, ASP.NET has the "MaxJsonLength" property of the serializer.)
