We have a requirement to establish an RPC style communication between a client and a server using Websockets. The server is an online ordering solution which needs to submit orders to over 5000 point of sales systems (POS) all over the US.

We downloaded your software and did some POC, however we are unable to find out how we can do a synchronous request/reply between the server and the client. In our case the server needs to issue the following calls to the client (POS) and get a reply on the same thread synchronously

  1. Call the POS to get the customer's personal information
  2. Post the credit card data and the order data to the POS and get a confirmation on the same thread

Is it possible to do RPC style communication using your product?

Thanks in Advance
