This is a Laravel 12 demo project showcasing how to integrate OAuth2 with Infusionsoft (Keap) using Guzzle HTTP client and Laravel, without relying on the official SDK. It covers the entire authentication flow, access token storage, refreshing, and consuming the API (fetching contacts) with a clean Laravel service structure.
- ✅ OAuth2 Authorization Flow with Infusionsoft
- ✅ Token storage in database (access + refresh tokens)
- ✅ Automatic token refresh if expired
- ✅ Display real-time contacts from Infusionsoft on a Blade view
- ✅ Laravel Service Class pattern used
- ✅ Modular, clean code ready for production adaptation
