2. How the GHIN API Works: Complete Technical Flow (Developer Guide)

Integrating GHIN requires a structured technical flow across authentication, score posting, and live data retrieval. This is where GHIN real-time data integration becomes essential.

Step 1 — User Authentication (GHIN Login)

Your app must authenticate golfers through GHIN using their:

• GHIN Number

• Last Name• Email (optional)

After validation, GHIN returns:

• Player ID

• Name

• Handicap Index®

Step 2 — Fetching Real-Time Player Data

Once authenticated, your app can fetch live golfer data through the GHIN Player API.

GHIN provides:

• Current Handicap Index®

• Club membership data

This fuels dashboards like:

This is the core of GHIN real-time data integration, enabling instant player updates.

Step 3 — Real-Time Score Posting Integration

GHIN supports live score posting — the #1 feature golfers expect.

GHIN Course API provides:

Once a score is posted, GHIN automatically:
