Providing an upstream identifier

Understand the purpose of specifying an upstream identifier.

The upstreamId can be any identifier that you want to associate with a Checkout, Invoice, or Order. Unlike metadata, you can use this value as a query parameter in GET requests.
For tracking purposes, we recommend you provide the universally unique identifier (UUID) that clients use to identify the corresponding order in their system.
