As of early April, right now WOWAPPS has no way of updating POS systems of the taxi status like we can using our own Bump-Bar system. See this article for more information.
While POS integrations will work and can happen as of today, note that you will need to be extremely careful of what the pick-up and delivery times are. Mentioned in this artical 'Must Read - Taxi Booking Time'
You as the vendor owner will still be emailed a tracking link once an order has been sent.
Please note, we're working hard to make this a little easier with the current plan/solution being able to see POS orders in the WOWAPPS Bump-bar. This will most likely involve having a small tablet near your POS.. However, more information will come around this shortly.
