PosGreen Implementation

Running PosGreen counters can accept WebSocket connections. They only accept WS:// protocol so cannot be connected from webpages running on https:// In general, you should not need to connect direct to counters so this does not impact. If you do nned to connect from HTTPS web pages, then install a SSL proxy such as Stunnel or Deno, etc

Connect URLs

PosGreen opens websockets on the following URLs

• /fd1/open_websocket

  Opens a normal FD1 websocket talking to PosGreen

• /fd1/open_websocket?purpose=presell

  Specifies that a presell connection is requested. This is a special mode that allows instore tablets to interact directly with the lanes POS database. You must use purpose=presell in the URL when connecting, as a seperate process will normally be created to manage the websocket.

fd1.session.login

The session login packet for PosGreen allows the following options

Parameter	Description
"purpose":"customerdisplay"	Indicates this websocket is being used for a customer display to show progress on the current sale. You must set this inside the session packet, not on the connecting URL
