Please be more specific. What do you want this API to do? (Keep in mind that an API receives one request and returns one response, and that unlike a websocket, an API cannot initiate a response in the absence of a request.)

This doesn’t answer my question, so I’ll rephrase it this way.

Imagine you have this API.

Some JavaScript code in your browser calls this API at some point in time.

What do you want to have happen on the server?

- What do you want the server to return as data?
- How soon after the API call is made do you want this data returned?

I can’t, because from the description you’ve provided so far, this doesn’t make any sense to me.

A websocket allows the server to initiate the transfer of data as a “server push”, where an API exposed to the client is a “browser pull”. They’re fundamentally two different operations.

That’s why I’m asking you to define what it is that you want this API to do - and to provide this definition _without_ referring to the notification code shown above.
