When does "orders/update" webhook triggered?

[abishekrs]

Could someone help understand what events trigger "orders/update"?

Do the following events trigger it?

• When a fulfillment for an order is created?
• When a fulfillment event on an Orders fulfillment is created?
• On transaction updates on an Order? (Like Refunds, Quantity increases)
• When an Order is cancelled?
• When Customer Address is updated.
• When Notes are added to the Order.

The reason I ask is because we use a database that charges based reads and writes and we want to make sure we keep the reads and writes to the minimal and not listen to duplicate events. It would be great

The 'orders/updated' webhook gets trigger by any update to the order. To answer your questions explicitly:

Do the following events trigger it?

• When a fulfillment for an order is created? Yes
• When a fulfillment event on an Orders fulfillment is created? Yes
• On transaction updates on an Order? (Like Refunds, Quantity increases) Yes
• When an Order is cancelled? Yes
• When Customer Address is updated. Yes
• When Notes are added to the Order. Yes

Hope this helps

In my case,  when I make a purchase - create an order in my new store -  'orders/updated' webhook arrives before or after 'orders/create' webhook within milliseconds from each other.

The store is new, no customization that would update the order automatically.
