Please request the UUID's from your Uber Eats account manager. They have access to those ID's.
Provide the order details to avoid receiving the UUID of another location if you have multiple. Adding your URL in your request always helps
Alternatively, if you urgently need to find them you can look in the page's source code to find the UUID.
On the Uber store where you want to find the UUID, right-click and navigate to 'View Page Source'
On the source page, find : \u0022stores\u0022:{\u0022
and the UUID should appear right next to it.
