Defold In-app purchase extension API documentation

This extension provides functions for making in-app purchases.

Usage

To use this library in your Defold project, add the following URL to your game.project dependencies:

https://github.com/defold/extension-iap/archive/master.zip

We recommend using a link to a zip file of a specific release.

For Facebook Canvas you also need to add the Facebook extension as a dependency.

Source code

The source code is available on GitHub

Supported platforms

The following platforms are supported by the extension:

• iOS - StoreKit
• Google Play - Billing 3.0.0
• Amazon - 2.0.61
• Facebook Canvas

Differences between supported platforms

Amazon supports two different product types: subscriptions and consumable products.

Google Play and Apple supports three different product types: subscriptions, consumable and non-consumable products.

If you want to simulate non-consumable products on Amazon you need to make sure to not call iap.finish() on the product in question (and make sure to not have enabled Auto Finish Transactions in game.project).

Calls to iap.buy() and iap.set_listener() will return all non-finished purchases on Google Play. (This will not happen on iOS)

The concept of restoring purchases does not exist on Google Play/Amazon. Calls to iap.restore() on iOS will return all purchased products (and have product state set to TRANS_STATE_RESTORED). Calls to iap.restore() on Google Play will return all non-finished purchases (and have product state set to TRANS_STATE_PURCHASED).
