API management is the process of designing, developing, documenting, testing, monitoring, securing, and optimizing APIs. Encompassing the entire API lifecycle, API management is critical to efficiently scaling APIs (both public and private) while also hardening them against potential threats. This also includes distributing those APIs to users and controlling access in a modern, multi-cloud context. 

Observability is a primary benefit of API management. By using a load balancer or another monitoring platform, developers can collect performance metrics and general health indicators to troubleshoot problems when they occur. Not only can this data help developers iron out performance issues, but it also helps counteract API abuse.

Organizations are using more APIs than ever before, making API management strategies vital to their success. Since continued API development often hinges on continued consumption (user growth incentivizing teams to add features, etc.), securing and accelerating APIs is crucial. These processes give external organizations the confidence to adopt APIs as part of their own applications. 

External API management platforms (AKA "products") also exist to simplify or offload many tasks. However, we'll mainly dive into the ongoing steps that go into API management below.

How does API management work?

API management is complex since there are so many pieces to the puzzle. However, understanding each step makes the process more approachable. Here's a brief description of each step: 

  • Design – This includes the initial factors that influence how APIs are built, such as intended functionality, data privacy concerns, user experience (UX) considerations, and business goals. This touches both private and public APIs. 

  • Development – This encompasses the structuring, coding, and (often) specifications-based approach to API creation. Developers will define endpoints, request and response behaviors, formats, and any backend database setups to support their APIs. 

  • Documentation – Once the API is built, API maintainers must create written instructions detailing how to use a given API. This includes information on endpoints, request/response behaviors, formats, and generally any API development parameters that could impact users. 

  • Testing – Driven by a shift-left philosophy, API testing helps uncover bugs and other vulnerabilities as early as possible, solving problems before they arise or reducing the blast radius of any such incidents (which ties into remediation). This ensures the API is working as anticipated while also shining a spotlight on usability issues. 

  • Monitoring – After an API enters production and is exposed to real-world usage, API maintainers can collect key performance and usage metrics. This offers insight into how people are using an API, and how the API responds to scaled usage. 

  • Securing – Important both during and following the testing phase, API security is a continual effort to harden APIs against evolving threats. This includes zero-day vulnerabilities, coordinated efforts such as DDoS attacks, and general abuse (intentional or unintentional). Best practices and industry standards are useful guidelines. 

  • Optimization – Once developers have data at their disposal, it's much easier to make targeted enhancements to API performance and resilience. 

API management takes plenty of planning to get right. Plus, API management never truly ends while an API is live. It's a continual, intentional effort to improve such APIs while arming teams with information to help them make informed development decisions. Numerous third-party tools can help streamline these processes and provide varying degrees of task automation. These may also include API gateways.
