Admin Buttons can now trigger Shopify Flow automations! We’re released the following triggers in Flow:

The Customer, Order, Product and Abandoned Checkout triggers pass the IDs for their respective objects to Flow, making it easy to build flows that access data from each model. The “Any detail page” trigger can accept a single “entity id” from any of the “detail page” target types in an Admin Button. The “Any selection page” work from list pages and can accept one or more entity Ids. The triggers also receive form and key-value data from the button, which can be parsed and used in Flow workflows.
