In the documentation, Order ID is said to be unique: https://developer.squareup.com/reference/square/objects/Order#definition__property-id
Is this order ID unique for ALL restaurants in a location (e.g. city/country)? That is, will different orders from different restaurants which are nearby in a physical location (say a city/country) also have IDs which are guaranteed to be unique from each other?
Or is there a probability that 2 orders from 2 different restaurants can have the same Order ID?
I need to know as what I am working on is a unique application. I need to know if all order ids in Square are unique to each other, regardless of the restaurant or merchant, or not. Thanks in advance!
P.S.: Also posted in Slack.
Also, I have the exact same questions for Location ID in Orders API?.
Is it unique across all of Square, regardless of the business or its location or proximity?
Thanks a lot in advance, this is really helping me use Square!
Order ids are unique across all merchants, same thing for location id (and merchant id for that matter).
Wow, even internationally, wherever Square is used?
That’s a great feature, if so, and very useful. Thank you so much!
Thank you, I apperciate your help as always!
Hi, I can’t find this information in the references, but is order “reference_id” enforced to be unique per merchant or merchant-location?
Is “reference_id” user-facing?
reference_id is a client-specified ID to associate an entity in another system with an order. There’s no requirement from Square on if it needs to be unique or not.
