Making HTTP API Calls in Go for Scalable Backend Services

Modern backend architectures rely heavily on communicating with external services and third-party APIs. To build reliable systems, a Go developer must understand how to initiate network requests, manage resources, and process data payloads efficiently. This text-based course guides you through the foundational mechanics of Go's net/http package, preparing you to integrate external APIs into your backend services. You will transition from writing simple network requests to developing production-ready API integrations that handle real-world network instability and complex JSON data structures. What you'll learn: - Understand the core concepts of the HTTP protocol and how Go's standard library implements them - Configure and dispatch GET, POST, and custom HTTP requests using the native net/http package - Decode JSON responses safely into Go structs using type-safe practices and modern custom deserialization - Implement robust error handling, manage request timeouts, and utilize context propagation to prevent resource leaks - Apply best practices for connection pooling and reusing default HTTP clients to ensure high-performance backend operations Starting with basic HTTP terminology and Go standard library imports, this course builds your knowledge step-by-step through clear written explanations and practical code scenarios. You will progress from basic GET requests to managing contexts, headers, and payload decoding. This course is designed for beginner to intermediate Go developers who want to master backend integrations. No prior experience with network programming is required, though a basic familiarity with Go syntax is recommended.
