What is the API for the App Store?

Apple has helped this thriving community of small developers build incredible apps with more than 250,000 application programming interfaces (APIs) included in 40 software development kits (SDKs).

Safari supports two APIs for implementing payment requests: Apple Pay JS API, and the W3C Payment Request API . Both APIs present the same Apple Pay payment sheet on Safari, and offer nearly the same user experience.
