Steps
Review the GPA Program Overview page to understand the Golfer Product Access pathway for individual-golfer-facing products
Check the GPA Approved Vendors list to see which products (e.g., Arccos, Golf Genius, TheGrint) are already licensed Handicap Data Affiliates
Submit the vendor interest form linked from the GPA Program Overview page to begin eligibility, pricing, and onboarding review
Once approved, integrate against the GPA API series to retrieve a player's Handicap Index, Course Rating/Slope data, and to post scores
Confirm your product complies with WHS Rules of Handicapping and USGA data-use terms before launch
Known gotchas
GHIN/GPA is not an open or self-serve API — access requires USGA approval as an Authorized Handicap Data Affiliate, which can take significant review time
The GPA program (consumer apps) is a different pathway than GHIN's club/association-facing handicap software — apply to the correct one
Course Rating and Slope data has its own public lookup (Course Rating and Slope Database) separate from the golfer handicap API
