IAP Button

An IAP Button is a ready-made purchase button. Tap it and it buys a product from your IAP Catalog, or restores what the player already bought. It handles the tap itself, so you don't need a Tappable on the same object. Works in Game and App projects.

Add it from Add Component ▸ IAP Button (under Interaction), or get a ready one with Add Object ▸ Buy Button: a button with a title and a price label already wired to the IAP Button. Just pick a product.

Settings

Setting	What it does
mode	purchase buys the one product picked below. restore brings back every non-consumable the player already owns, for example after reinstalling. It has no product of its own.
product	Shown in purchase mode. Which IAP Catalog product this button buys. If the catalog is empty, the card tells you to add one in the IAP Catalog window first.
title text	Optional, purchase mode. Drag in another Text or Button from the screen. On a real watch, its words are replaced by the product's title from the store.
price text	Optional, purchase mode. Same idea, but shows the store's formatted price in the player's own currency.
On Purchase Complete	Actions that run after a successful purchase or restore.
On Purchase Failed	Actions that run when the store reports an error or the player cancels.

What happens on a purchase

When a purchase goes through, the product's own catalog settings are applied first: a consumable adds its amount to its count variable, and a non-consumable sets its owned variable to 1. Then On Purchase Complete runs. Use it for a thank-you message, a sound, or to hide the button.

Testing in Preview

Preview never talks to a real store, so it can't show a real purchase:

• Tapping a button with a valid product always succeeds straight away.
• On Purchase Failed only runs in Preview when the product is missing from the catalog. That's a setup mistake worth catching.
• title text and price text keep their own words in Preview. The real title and price show on a watch.

Test cancellations and errors on a real watch.

Good to know

• If the product is removed from the IAP Catalog, the card shows a warning, and tapping the button runs On Purchase Failed instead of buying anything.
• Works on both Wear OS (Google Play Billing) and Apple Watch (StoreKit).
• Not available in Watch Face projects, since a watch face can't run a purchase.
