I looked into the different order webhooks and was wondering when they are triggered. This is what I figured out so far:
orders/updated
is fired whene
I'd say for sake of keeping the code easier to understand it would be in your best interest to handle the appropriate webhooks just to keep the code easier to understand.
If all you're doing is tracking really general stuff, it's probably fine.
Also, on all state changes of an order the orders/updated
webhook is fired.
