Our Patterns for API Design, also known as Microservice API Patterns (MAP), capture proven solutions to problems commonly encountered when specifying, implementing and maintaining message-based APIs. MAP focusses on message representations – the payloads exchanged when APIs are called. These payloads vary in their structure as API endpoints and their …

Our Microservice API Patterns (MAP) distill proven solutions to recurring service interface design and specification problems such as finding well-fitting service granularities, promoting independence among services, or managing the evolution of a microservice API. This article establishes context and scope of MAP, highlights service design challenges, and suggests …

Part 2 of our book features 44 patterns in its Chapters 4 to 9: Chapter 10 presents two real-world systems in which pattern instances can be found; Chapter 11 is a retrospective and outlook. A pattern eligibility cheat sheet is included in the book as well (Appendix A). Its online predecessor is available here. Appendix B provides ...

The book features a more extensive cheat sheet for pattern selection in its Appendix A, which also discusses how our patterns relate to ADDR, RDD and DDD.. The cheat sheet is ordered chronologically. Its issue-pattern tables suggest when to apply which pattern. 1. Warning: The cheat sheet is a gross simplification of a set of complex design considerations; API design is a …

News (November 2022): Our book “Patterns for API Design: Simplifying Integration with Loosely Coupled Message Exchanges” provides decision narratives in its Chapter 3 (the book table of contents is here).These narratives serve as a large-scale tutorial for pattern application. Tutorial 0: Orientation and Single Pattern. This tutorial is the “Hello World” of API design with MAP.

Pattern: API Key a.k.a. Access Token, Provider-Allocated Client Identifier. Context. An API provider offers services to subscribed participants only. For various reasons, such as establishing a Rate Limit or Pricing Plan, one or more clients have signed up and want to use the services.These clients have to be identified.

Patterns for API Design. The Book; Resources; Tutorials; Patterns; About; Pattern Categories Our microservice design patterns can be grouped by lifecycle phase, level of abstraction and refinement, and type of design concern. Each of the resulting categories investigates a set of related design issues.

Dec 19, 2024 · Our co-author and principal consultant Daniel Lübke has given several presentations about our API design pattern language at industry conferences: First, he talked about the integration of our patterns into the ADDR process by James Higginbotham at the API Conference in Berlin (speaker/session information) and then at the W-JAX conference in Munich.

Step 5: Evolution Patterns. The API design has now reached a sufficient level of elaboration so that it can be tried out with beta users. Step 5.1: Selection of an (initial) Evolution strategy. Task: Which pattern describes how to make an initial release to get early feedback (“commitment-free API beta program testing”)?

Pattern: Public API a.k.a. Open API (a truly open API is a Public API without an API Key or other authentication means). Context. It has been decided to provide a system with a remote API that exposes one or more API endpoints. The API clients that are supposed to use the API (and therefore must reach it) reside in different organizations, possibly even in different countries.
