Introduction to selling in-app

The Paddle SDKs offer a convenient way to make use of Paddle’s features inside of your Mac, Windows, and iOS apps - features like our checkout, trials, and licensing.

Note: Paddle’s docs refer to v4 of our SDK. If you are looking for documentation related to v3, please click here.


The SDKs make it easy to open checkouts in-app, for a better user experience (and typically an improvement in conversion rate)


You can offer trials to your users prior to purchasing, allowing them to try your software over a period of days that you define.


Licensing plus the checkout provides an end to end solution for access control to your apps. Paddle can issue licenses on a purchase and the SDK can activate and validate these.
