API Chaining
API chaining is a programming technique where multiple API calls are executed sequentially, with the output of one call used as input for the next. It enables complex workflows by combining simple, discrete operations into a cohesive process, often used in microservices architectures or when interacting with external services. This approach helps manage dependencies between API requests and streamline data processing across distributed systems.
Developers should use API chaining when building applications that require data from multiple sources or need to perform a series of dependent operations, such as in e-commerce checkouts, data aggregation pipelines, or multi-step authentication flows. It is particularly valuable in serverless environments or when orchestrating microservices, as it reduces manual coordination and improves efficiency by automating sequential interactions.
