2. Set up Developer Account:

Create a developer account on the chosen app store platform(s) and enroll in their developer programs.

3. Understand the APIs and Frameworks:

Read the documentation and guidelines provided by the app store platform(s) to understand their in-app purchase APIs and frameworks.
