List Sessions

Pay at Table integrations are currently standalone from Pay at Counter and Online payments. This is because the current version of the Tables API uses an asynchronous WebSocket protocol for its messaging.

The ListSessions operation requests a list of multiple sessions.

SUB /ListSessions

If filtering parameters have been specified, the response from the EPOS should contain only those sessions that satisfy all specified filters. If no sessions match the filters, the EPOS will return an empty list. If no parameters are set, the response will include all sessions stored on the EPOS.

1. Receive a listSessionsRequest from Dojo.
2. The EPOS should respond with a listSessionsResponse.

In the following example, the isPayable and hasTable booleans are set to true, while isFinished is set to false. This indicates that the request is searching for sessions that are seated, have ordered items, but have not yet paid for their meals.

{
  "jsonrpc": "2.0",
  "id": "9420313f-91ff-49b9-af9e-33977426daaa",
  "method": "ListSessions",
  "params": {
    "isFinished": false,
    "hasTable": true,
    "isPayable": true,
    "tableNames": [],
    "requestorInfo": {
      "requestorType": "REQUESTOR_TYPE_CARD_MACHINE",
      "cardMachineRequestorInfo": {
        "terminalId": [],
        "waiterId": 1
      }
    }
  }
}

PUB /ListSessions

ListSessions will return a listSessionsResponse whether the request parameters match any available sessions or not. If they do not match any sessions, the sessions object will still be returned, but it will be empty. If the parameters are left empty, the response will include all sessions currently stored on the EPOS.

In this example, the request has matched two tables stored on the EPOS. Both tables have the isPayable boolean set to true. Because the request did not specify a tableNames value, the response includes two separate tables. Because the waiterId was specified as 1, the response only i ncludes tables associated with the relevant waiter (in this case, John Smith).
