Modern applications rarely work in isolation. They often communicate with payment gateways, authentication providers, email platforms, CRM systems, cloud services, and other third-party applications through APIs.
In this chapter, students will learn how APIs work and how Lovable AI can be used to integrate external services into real-world applications.
The chapter covers API fundamentals, REST APIs, API requests and responses, authentication methods, payment integrations, email services, social login systems, third-party APIs, security practices, and practical business use cases.
By the end of this chapter, students will understand how to connect applications with external systems and build feature-rich software that interacts with real-world services and platforms.
