Hey Guys,
I am trying to query live data for open tickets e.g. ticket name, order details on the POS
I have read most of the docs and tried locating it in the ‘Orders’ but it only shows order details that don’t match up to a live ticket, I can’t seem to get any live data for OPEN tickets?
Can anyone please assist?
At this time Open Tickets that are created and paid for on the POS isn’t currently available with the Square APIs. We’re constantly working to improve our features based on feedback like this, so I’ll be sure to share your request to the API product team. 
Allow me to second the need for this data. I need to know real-time what my sales are and items pending payment in an open ticket/cart need to be a part of it.
Any news on this? We’d like to create hooks for real time inventory management (including for example, translating wine glass sales to wine bottle inventory), but at the moment this can only update after the check is paid.
At this time there’s no further updates on this. We hope to have more for you in the future.
Hey Bryan, It’s been another year - any update on this?
At this time the ability to get open tickets from the POS isn’t currently available. When our orders migration is completed then more options will become available.
I’m seeing a different result now so I assume this has changed? I can see all orders created via POS (restaurants)
Yes, this is part of our orders migration.
This is great news, you’re about to have a bunch of happy developers. Anywhere we can see the progression of this so we know what is actively available?
At this time there isn’t a place to track the progress. Please note that this isn’t available with all sellers yet. 
Hi Bryan, as part of the Orders migration we can now pull open tickets from the POS through the API? I dont seem to be able to do this.
At this time you’ll only start to see this behavior with the Restaurants POS for some sellers.
Ok great, how do I access this feature if I am working with a restaurant merchant?
There’s really no one way to access this. You’ll just start to be able to see all the orders. Please remember that this isn’t available for all sellers as its just rolling out.
Thank you Bryan for this info. I just want to be able to retrieve open tickets from a merchant’s square POS. If i use the Orders API and retrieve open orders will the open tickets be retrieved? Second, you said its only available to certain sellers. How do you know which sellers, and how does a seller obtain this
ability if they do not have it?
