Sending JSON data via a POST request to https server - json

Question

Please help, maybe anyone had experience of sending and receiving data through json via a POST request to the server?
There is programming interface (API) to it by passing json data you need to pass the parameters (method, id, params) and get the session ID (result).
Use the library: com.thetransactioncompany.jsonrpc2
The problem is that at the stage of submitting the data (respIn = JSONRPC2Session.send(reqOut) the request falls off with the 500 error, but the server is available, it did not seem to understand that this is a post request, what is my mistake?
NetworkException:
java.io.IOException: Server returned HTTP response code: 500 for URL: https://online.sbis.ru/auth/service/
