Uber and doordash integration -- 2

I’d like to integrate the Uber eats and doordash orders through to my POS system. I have the api for the pos system as well as Uber eats and doordash. We currently have our own online website that sends orders from the website to the POS system. We’d like full integration including menu building and receiving orders. First step is to send new orders to the POS system. Then, we need to update the system to allow for menu integration.

To see exactly what we want please watch this video:
