TSG (The Strawhecker Group), a global leader in payments analytics and consulting, is proud to honor standout companies for API excellence and innovation.

The annual API Best of Breed Report, powered by TSG’s Global Experience Monitoring (GEM) platform, ranks payment gateways’ overall APIs across a comprehensive set of factors to provide insights, benchmarks, and recommendations for their developer integration experience. The assessment provides a lens into the developer mindset, both novice and experienced, on how APIs are perceived externally.

Mike Trilli, GEM Product Manager, explains, “API performance is no longer just a technical metric; it’s a business differentiator. Our insights help companies align their developer experience with market expectations before writing the first line of code. This focus extends beyond a technical metric and into a competitive differentiator to drive business strategies.”
