APIs Are Gracefully Deprecated and Retired

All APIs must follow a formal deprecation and retirement process that provides consumers with adequate notice, migration support, and a clear timeline from deprecation to removal, ensuring that no consumer is left stranded when APIs reach end-of-life.

Policies

Deprecation

Deprecation is how you communicate that an API is on its way out. Having a clear policy for timelines, headers, and communication gives consumers the time they need to migrate without panic.

API Retirement

Retirement is the end of an API's life, and it needs to be handled with the same care as the launch. Clear timelines, communication, and migration support make the difference between a clean shutdo...

Breaking Changes

Breaking changes are the thing consumers fear most. Defining what counts as breaking, how it gets reviewed, and how it gets communicated is essential for maintaining trust across the API landscape.

Migration Guides

Migration guides are what consumers need when you ship a new version. Step-by-step instructions, breaking change summaries, and code examples make the difference between a smooth transition and a p...

Versioning

Versioning is how you communicate change to consumers. Whether you use semantic or date-based, being explicit about your versioning strategy and sticking to it builds confidence that change is mana...

Change Log

A change log is essential for tracking everything that has been added, updated, or removed. I look at change logs as the honest record of an API's evolution that builds trust with consumers.

Experiences

Alignment

I see product and engineering teams talking past each other constantly when it comes to APIs. Without alignment on the why behind each API, you end up with technically sound resources that nobody a...

Change

Change is the one constant across the API landscape, and I watch teams struggle with it every single day. If you aren't actively managing and communicating change across versions, deprecations, and...

Communication

I struggle with how little communication happens between the teams producing APIs and the people consuming them. Blogs, changelogs, roadmaps -- these are building blocks that most teams just skip, ...

Reliability

Reliability is where the rubber meets the road in the API landscape. If your APIs aren't up when consumers need them, and if new versions don't land smoothly, none of the other building blocks matter.

Trust

Trust is earned at the API level, and I see it broken constantly. When consumers don't trust that your API will be there tomorrow, behave the same way it did yesterday, and protect their data, they...

Stability

Stability is what consumers are really asking for when they evaluate your API. I see breaking changes, outages, and weird behavioral shifts erode trust fast. If people can't depend on your API for ...
