12.00pm: Linting API Descriptions: Why consistency is king for Developer Experience! (Erik Wilde)

API descriptions are describing the surface of an API so that it is clear how an API works. It can be a good idea to check these descriptions against general good practices or against specific internal good practices for API designs. Linting is the process that allows those checks to be performed, by taking the description, letting a linter inspect it, and then get warnings or errors regarding the API design.
In this workshop, we look at the various motivations to use API linting. We then specifically look at HTTP-based APIs, OpenAPI as their description language, and Spectral as a popular open source linting tool. Spectral performs opinionated linting out of the box by having a set of build-in rules. Spectral allows users to add their own rules or completely replace the built-in rules. Spectral also supports modularization so that for example in larger organizations, different APIs can use different combinations of rules for various APIs. In this workshop we cannot give a complete tutorial of Spectral, but you will walk away with a good understanding of when to use it, how to apply it to your use cases, and what its general capabilities look like.

1.00pm: Introduction to Contract Testing: Evolving APIs Safely (Frank Kilcommins)

Microservices and modular API architectures have transformed the technical landscape, enabling rapid innovation, faster releases, and decentralized evolvability. However, scaling these architectures introduces significant challenges. Managing dependencies between providers, consumers, and environments often leads to API sprawl, increasing complexity and diminishing returns. Traditional reliance on integration and end-to-end testing struggles to keep pace, resulting in high costs, lengthy feedback loops, and the rise of “zombie APIs.”
Contract testing offers a scalable and efficient alternative to address these challenges, rebalancing the testing pyramid by focusing on the interactions between API providers and consumers. With bi-directional contract testing, teams can leverage existing OpenAPI artefacts and design-first workflows to validate changes without needing expensive, brittle end-to-end setups. Providers gain insight into the impact of API changes, while consumers understand the surface area of APIs they rely on.
We will cover:

The limitations of end-to-end testing in modern API architectures.
How contract testing reduces complexity and promotes collaboration.
The fundamentals of provider and consumer workflows for bi-directional contract testing.
How to leverage tools like Pact to maximize OpenAPI investments and enable faster scaling.
Demonstrations showcasing contract testing in action.

Whether you're navigating a microservices ecosystem or building a modular API platform, this workshop will empower you to evolve APIs safely, deliver value faster, and streamline your testing strategy. Join us to bring clarity and confidence to your API architecture.

Overview
apidays Paris is the flagship conference from the apidays family, and this year returns with the title “The Future API Stack for Mass Innovation”. As the conference title suggests, the agenda will provide perspectives on how APIs and related technologies will supercharge the growth of organizations through technology innovation.
apidays Paris has much to offer with many different topics on offer. AI is a hot topic, with much to say on the role of AI in API development and the symbiosis between AI and APIs. However, the agenda also covers architectures such as cloud-native, advanced API lifecycle management and API governance, and the role of APIs in green technology. Whatever your role or interests, apidays Paris offers the opportunity to dive into a wealth of API knowledge, in the company of many subject matter experts, with subjects including:

API Lifecycle Management, API description languages (OpenAPI, AsyncAPI, JSONSchema) API Security, API Design and Documentation
Cloud Native Infrastructure (Containers, Kubernetes, Ingress, Istio, etc)
GenAI (OpenAI, Claude AI, Mistral AI), Open Source ML, Prompt Engineering, and Prompt Security
GreenIT and GreenOps within the GreenIO conference (colocated with apidays)
No-Code and Citizens Developers within the Enterprise No-Code Conference (colocated with apidays)

The variety and breadth of topics offered at apidays Paris are matched by how far OpenAPI reaches into the API ecosystem. OpenAPI has become the de facto API description language for API providers and is critically important for delivering high-quality and well-described APIs. Regardless of your chosen subject area, providing or consuming OpenAPI descriptions is vital to how you work with APIs.
The OAI track returns to apidays Paris for a second year. Knowledge of OpenAPI and our new specification Arazzo is a must-have for IT and business leaders who seek to drive their organizations forward through AI and APIs. Join us to learn more about how OpenAPI can provide you and your organization with a strategic advantage in adopting AI and how you manage your APIs throughout the entire API lifecycle.

OpenAPI for Code & Docs Generation: Lessons from 1 Million API Definitions

Speaker: Sohaib Tariq, Product Manager at APIMatic
Abstract: OpenAPI-based Code Generation has become Ubiquitous. You can take your pick of Opensource or Proprietary tools that require only your OpenAPI Definition to generate API Clients and Reference Documentation. However, OpenAPI and other popular API specification formats do not enforce any standards for Code Generation. Thus we often see Code Generators creating ugly or downright unusable code for API Definitions that are Syntactically and Semantically correct. This talk will draw upon the learnings from analyzing over 1 million API Definitions in various formats, predominantly OpenAPI/Swagger. It will highlight common mistakes made by Developers which are not typically highlighted by OpenAPI Validation and Linting tools but can negatively impact the quality of generated Code and Documentation. The talk will emphasize how the right validation and linting process can help you overcome all of these issues efficiently in order to help you build a world-class Developer Experience for your API.

API Gateway integration with Identity Management

Speaker: Madhu Sudan Jangid, Fractional CTO at Mission Plus
Abstract: How API Gateways can be used to enhance security postures of an Organization. The decision factors of choosing a right Gateway tool for different use cases. Different design patterns and how the limitations can be solved for the said patterns.

OpenAPI Mini Summit April 2024
2024-04-15 09:00 - 12:30 (America/Los_Angeles) | Seattle Convention Center, 900 Pine St, Seattle, WA, 98101, United States
Event: OpenAPI Mini Summit Seattle 2024
Date: April 15, 2024
Venue: Seattle Convention Center, Summit Building
Overview
The OpenAPI Mini Summit is part of the Linux Foundation Open Source Summit North America 2024.
The Mini Summit is a chance for OpenAPI supporters to get together for face to face meetings while attending the LF Open Source Summit. The main focus will be the soon to be deployed Workflow specification. The Workflow spec shows promise to have a large impact in the API deployment and consumption community. Much of what is done around API and related specifications is focused on the developer. This new spec will help the developer but the larger impact will be for those who consume APIs. This specification details how you can document how your API is used in context with the APIs that preceded it and what follows. This in a machine readable format to lend itself to support automation. The adoption of the spec will benefit all through the reduction of labor and time to market not just in the deployment of APIs but the consumption as well. APIs do not generate value until they are used.
We had a half day Monday morning the 15th of April. Following the presentation, we had a discussion on how better API documentation would address the issues some of the attendees raised as questions.
OAI Mini Summit Agenda

Introduction to OpenAPI and our mission.
Current activities and focus areas.
Summary of the soon to be published workflow specification.
A peak into future releases.

apidays Paris December 2023
Post Event Report
Conference Theme
In today’s intricate digital landscape, APIs have emerged as powerful conduits for innovation, bridging the gaps and unlocking new realms of possibility. This year, apidays Paris revolves around four strong pillars: “Software, Sovereignty, Society, Sustainability.”
Software: Software & APIs are the pulsing heart of the digital revolution, from the frameworks that power global platforms to the microservices optimizing niche solutions, Serveless, Kubernetes, Kafka, and many other technologies.
Sovereignty: How should sovereignty be defined in the age of the cloud, decentralization, and ubiquitous connectivity, all while empowering individuals and organizations to chart their distinct digital paths?
Society: Let’s understand the societal implications of rapid technological advances to ensure that we leave no member of society behind, fostering an equitable and harmonious future.
Sustainability: Let’s explore the sustainable development, deployment, and management of software solutions to grasp the importance of eco-friendly digital infrastructures, ethical AI, and the long-term impact of our digital choices.
OAI Track Program Recap
apidays Paris was the 3rd and largest OpenAPI track program so far which consisted of 11 presentations over 3 sessions. The event was very well-attended with ~3500 registrations. Loads of posts to LinkedIn, here are the main posts from the event:

LinkedIn post December 5: 2473 impressions (as of 12/11/23)
LinkedIn post December 6: 3441 impressions (as of 12/11/23)
LinkedIn post December 7: 3396 impressions (as of 12/11/23)
LinkedIn post December 8: 1982 impressions (as of 12/11/23)

The OAI Track sessions were happening on two days, two of them on December 6 and one on December 8. There were more people on December 6 but that was probably because there were fewer competing tracks on that day. On December 8 we were in the afternoon, so some people were already leaving but there still was competition from 7 other tracks. However, in all sessions we had full rooms and good engagement from the audience, oftentimes hanging out in the room after the session to further discuss with speakers.

Post Event Report

Summary
This was the first “OAI Track” that was organized by an OAI as a partner with openapis. There are two follow-up events rather soon (Australia in October and Paris in December). The event went very well, we had a good program, the room was at capacity, and we had good feedback from people at the event and online. Erik Wilde initiated his role of OpenAPI ambassador to lead partner engagements.
Erik posted a few updates on social media leading into the event, including an interview with Mehdi Medjaoui and one with Mike Amundsen. There were various other activities as well, a complete list can be found in the “API Days London 2023 Social Posts” document.
The introductory track presentation combined some history, a brief presentation and explanation of OAI, a brief look at the specs under development, and an outlook at the development of OpenAPI 4.0. The other presentations focused on analyzing OpenAPI documents (José), how to use OpenAPI in API landscapes (Lorna), and the upcoming workflows specification that augments OpenAPI (Frank).
