Intergrate 3rd party app for Cocos Creator games

I am new to Cocos Creator (and Cocos2dx, too). I'm planning to develop a game for iOS, Android and Web platform.

Is it possible to integrate these apps to game developed by Cocos Creator:

• Appflyers, Google Analytics, Firebase (for tracking user)
• In-app purchase (for Android and iOS)

SDKBOX may help you. Intro: http://www.sdkbox.com

You can read this manual for integrating SDKs
