I would like to clarify this further against the examples payloads used in the webhook docs.
In the example below, it looks like most of the order ids and line item ids are larger than the max safe integer as defined in IEEE754.
For example, pasting the order ID to a browser console:
820982911946154508 > Number.MAX_SAFE_INTEGER true
I would like to understand if these examples are intentional and represent what may happen eventually.
