What is APIs?
APIs (Application Programming Interfaces) expose data from external services in a structured format, typically JSON or XML over HTTP. Many data pipelines pull data from third-party APIs such as payment processors, marketing platforms, or social networks. Rate limits, authentication, and schema changes are common challenges when ingesting from APIs.
