Yes you can!

All GameSalad subscribers can access money-making features such as In-App Purchase and ad networks, but you must be a GameSalad Pro subscriber to publish these apps to platforms other than the GameSalad Arcade.

Here are some useful articles that explain how to implement ad networks and IAP in your GameSalad project:

• Ad Networks
• In-App Purchase

Note: All revenue earned by your apps is paid directly to you from the platform owner (Google Play, Apple, Amazon, etc). GameSalad does not charge any royalties or revenue sharing on published apps!
