I can't seem to find any options in Shopify. I have multiple staff using my Shopify store account and I would like to received a notification every time they process a refund to see how we can send a survey to them and make sure the customer service is reaching out to them
If you're on Shopify Plus, check out Shopify Flow, that should do the trick.
If you're not on Plus, check out Order Automator. This isn't a standard feature yet but can be built in as a free customization (I'm the lead developer of the app and can hook that up for you :D).
If you don't want to use an app, you could create an SOP for your staff members for the actions they should take when refunding an order (example: 1) click on return item, 2) .... 3) after the refund email me with a link to the order, etc).
