APIs Support Event-Driven and Asynchronous Patterns

APIs that require event-driven or asynchronous communication must follow consistent standards for webhook registration, payload formats, retry policies, and delivery guarantees, enabling reliable and predictable event-driven integrations alongside synchronous request-response patterns.

Policies

Asynchronous and Webhook Patterns

Webhooks and async patterns are how APIs handle event-driven integrations. Registration, payload formats, retry policies, and delivery guarantees all need standards to keep these patterns reliable.

Long Running Operations

Long-running operations that can not complete synchronously need clear patterns. 202 Accepted responses, polling endpoints, and status reporting give consumers a consistent way to track async work.

Idempotency

Idempotency is one of those design principles that separates reliable APIs from fragile ones. Knowing which operations are safe to retry and how idempotency keys work prevents duplicate processing ...

Hypermedia

Hypermedia links in API responses let clients discover what actions are available dynamically. It reduces the coupling between clients and servers and makes APIs more self-describing and navigable.

Experiences

Consistency

When I look across the API landscape, consistency is one of the biggest challenges I see. Every team does things differently, and the surface area of inconsistency just grows until governance becom...

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.

Quality

I see the quality of APIs eroding across the landscape. Teams ship fast and never look back, but consumers feel every rough edge, every missing example, every inconsistent response. Quality is what...

Interoperability

Interoperability is where standards really earn their keep in the API landscape. When every API uses different formats, patterns, and conventions, consumers pay the tax every time they try to integ...

Developer Experience

Developer experience is the thing I'm most passionate about across the API landscape. Poor docs, missing examples, inconsistent patterns, and no tooling -- these are the things that make developers...
