RPC.Call to mDash

Hi again,

I recently created another topic because I am having trouble sending notifications with Dash.notify in api_dash.
While I find the solution I have tried sending RPC messages with

RPC.call ('wss://mdash.net/api/v2/rpc', 'method', {data: 'data'} .......);

and it can serve me.
The only question is to know if I am doing something wrong from the point of view of the mDash service or if it is correct to send an RPC to wss://mdash.net/api/v2/rpc.

Thanks in advance for the answer.
