Modal

Deprecated

Product subscription app extensions won't be supported as of February 9, 2026. You should migrate existing product subscription app extensions to purchase options extensions.

Modals are overlays that prevent merchants from interacting with the rest of the application until a specific action is taken.

Modals are disruptive by design, requiring merchants to take an action before they can continue, so use them thoughtfully and sparingly.
