Pass parameters via POST (or GET)

[jawache]

I think this works fine in development but won't work in production (at least not with stability), you can't be guaranteed that INVOICE will have the data you need (e.g. if more than one server is running your code the other server INVOICE will be blank) also what will you do if more than one user is using the app.

I would change this so the client app, web app, stores the settings and sends them all to this endpoint via a GET request and query params e.g. invoice?a=1,b=2 etc...
