API monitoring and observability are ways of monitoring application program interfaces (APIs) to gain insight into their availability, performance, and proper functionality. The article discusses the definition of API monitoring and observability as well as the difference between them, their importance for building successful and scalable APIs and how they’re being used inside LinkApi. While API monitoring allows you to check for your API status, errors and timeouts, API observability is all about making our API observable rather than only being able to debug what we’d thought to log or monitor in advance. Observability is based on exploring properties and patterns not defined in advance, the core of observability.
