About This Book

### Webhooks with C# and APIs: A Practical Guide to Event-Driven Architecture Transform your C# applications with the power of webhooks and build responsive, scalable systems that communicate in real-time. This comprehensive guide takes you from webhook fundamentals to enterprise-grade implementations, providing practical solutions for modern .NET development. **Master Real-Time Communication** Move beyond traditional polling mechanisms and embrace event-driven architecture. Learn how webhooks revolutionize application integration by enabling instant notifications when meaningful events occur, reducing server load and improving user experience. **Hands-On Implementation with C# and .NET** Every concept is backed by practical, runnable code examples using ASP.NET Core, Entity Framework, and modern .NET practices. Build complete webhook systems from the ground up, including receivers, dispatchers, and management dashboards. **Production-Ready Solutions** Go beyond basic tutorials with enterprise-focused topics including security implementation, retry mechanisms, failure handling, payload versioning, and serverless deployment strategies. Learn to build webhook systems that scale and maintain reliability in production environments. **Third-Party Integration Expertise** Master integration with popular services like Stripe, GitHub, and Shopify. Understand common webhook patterns and implement robust solutions for payment processing, CRM synchronization, and automated workflows. **Complete Reference Resource** Includes comprehensive appendices with sample payloads, HTTP status codes, middleware implementations, and interview preparation materials. Perfect for both learning and ongoing reference. Whether you're building microservices, integrating external APIs, or designing event-driven architectures, this book provides the knowledge and tools needed to implement webhooks effectively in your C# applications.
