A comprehensive guide to crafting asynchronous and synchronous APIs using Domain-Driven Design. Learn collaborative API design between IT and business experts, covering OpenAPI, AsyncAPI, and api design in greenfield as well as modernization strategies for legacy systems.

A hands-on workshop exploring how to use the API Product Canvas for designing AsyncAPIs. Learn practical techniques for collaborative API design that brings together business stakeholders, architects, and developers to create well-structured event-driven APIs.

Learn how to use the API Product Canvas methodology to design AsyncAPIs in collaborative workshops. This talk, presented with Annegret Junker, demonstrates practical techniques for creating event-driven API designs that align business requirements with technical implementation.

OpenAPI is a great specification language for RESTful APIs, being machine-readable and well-suited for both developers and business analysts. However, when designing APIs in collaboration with IT and business, the YAML or JSON-based standard can be overwhelming for non-technical people. To better communicate API specifications, we developed the API Product Canvas, a tool that helps communicate API specifications with ease. We will present our learnings from designing APIs with IT and non-IT people and how to get to a result in a collaborative way to make well-architectured, business-oriented APIs that are understood by developers and work in production. The audience will be equipped with a new tool: the API Product Canvas, for communicating APIs.
