How exactly to integrate web sockets ?

[ser]

1. I think you should read electrum docs first, including merchant chapter.
2. We are planning to deliver other templates, but until they are ready, look at javscript part of index.html and just add address in there.

I have read it again and so far everything works fine except for the web socket part, which I don't understand what to do, there is not enough information on how to successfully implement the websockets. JSONRPC is working fine with curl, but I need a way to know whether or not the user has paid the invoice which can be done using sockets only.

Maybe this guide will be helpful, then? http://yz.mit.edu/wp/web-sockets-tutorial-with-simple-python-server/

Well that just shows hosting a simple socket server. You mean I just need to run an empty web socket server with nothing coded inside it and electrum will take care of everything by itself ?

If you followed electrum merchant docs, the simple socket server already works for you. The tutorial is useful to see how the javascript part is constructed.

I am not sure if it is actually working or I am not doing something right. I see this message in browser console when I test a payment request:

JQMIGRATE: Migrate is installed, version 3.0.1

WebSocket connection to 'wss://Server IP Address:7246/' failed: Error in connection establishment: net::ERR_CONNECTION_REFUSED
(anonymous) @ index.html?id=5835f9a531:77

I also noticed that it is using "wss", I did not configure https, perhaps this could be the issue ? But why is it automatically using wss (https) model, I don't need it, is there any way to let it use ws instead of wss ?

You can't use electrum merchant without providing keys for SSL. It is clearly stated in requirements on the top of documentation chapter.

merchant documentation was updated for 4.0
websockets do not require an installation anymore
