PaySim Merchant

Summary
PaySim Merchant is a payment simulation platform designed for testing compliance and interoperability. It allows developers to simulate payment transactions and integrate with third-party systems. The app is available on the Apple App Store.
Rationale
PaySim Merchant, as described, is a payment simulation platform. This aligns with 'payment processing' as it simulates payment transactions. The description also mentions enabling 3rd party integrations, suggesting it has some level of 'developer API integration'. However, the app primarily focuses on simulation rather than real payment processing, hence the moderate confidence score.
