Custom API
A Custom API is a tailored application programming interface designed to meet specific business or technical requirements, often built from scratch or by extending existing APIs. It enables communication between different software systems, allowing data exchange and functionality integration in a controlled, documented manner. Developers create custom APIs to solve unique problems, optimize performance, or provide specialized services not available in off-the-shelf solutions.
Developers should learn and use custom APIs when standard APIs lack the necessary features, performance, or security for a particular use case, such as in enterprise applications, IoT devices, or niche industries. They are essential for building scalable, maintainable systems that require precise control over data flow, authentication, and business logic, enabling seamless integration between custom software components or with third-party services.
