Custom APIs
Custom APIs (Application Programming Interfaces) are bespoke interfaces designed to enable communication and data exchange between different software systems, tailored to specific business needs or workflows. They define protocols, data formats, and endpoints for applications to interact programmatically, often built using web technologies like REST or GraphQL. This allows organizations to expose internal functionality, integrate with third-party services, or create modular architectures.
Developers should learn and use custom APIs when building scalable applications that require integration with external systems, need to expose data or services to clients or partners, or aim to decouple components for maintainability. Specific use cases include creating microservices architectures, developing mobile or web app backends, automating business processes, or enabling interoperability in IoT ecosystems.
