Why API Design Matters, Where it Fits, & How to Get Started

Humanity’s greatest works of art started with a design-first approach. Your APIs are no different. Learn how to infuse the design-first mentality throughout the totality of your full API management lifecycle. Let’s walk through the problem, why it matters, what resources you have available, and how you can set your API program up for your success.

API Design in the Lifecycle

What is API Design

In a software development lifecycle where APIs are an afterthought, the results are vulnerability, inconsistency, time, and lack of adoption.

Connect APIs to a Product Mindset

APIs are a Product

APIs are a product and should be treated as such. In an API design-first development process, API architects begin with writing a specification and engaging all stakeholders in the process from its inception. The result of a design-first process is an API product that is comprehensive, consistent, and understandable by both collaborators and machines. Treating your APIs as products means using a design-first approach to produce the best possible product.

API DESIGN LIFECYCLE STAGES

How to Solve Your API Problems

Full API lifecycle management is the process of overseeing an API from its creation to retirement across its full life span. This includes everything from designing, publishing, documenting, securing, and analyzing APIs. When it comes to breaking down the API Design process itself, there is not a single approach or one “right way.” Instead, we need to lean on proven practices for design to inform the process. Here at Stoplight, we call this the API Design Lifecycle Stages, consisting of the following stages: Definition, Discovery, Design, Document, Collaborate and Govern.

Define

Define what approach you’ll take to lay the foundation of your API program. Outline the goals of your program and the desired outcomes, then access what approach makes sense for you.

Discover

You need to have visibility and discoverability into the APIs you’re running in production. API discovery is the ability to search and find different API resources that you can use to seal the loopholes in your existing workflows. Having an overall view of all APIs currently being designed, deployed, monitored, and deprecated is crucial to scaling a successful API program.

Design

Create high-quality API designs in line with industry best practices and organizational needs by enforcing built-in or custom style guides. The API design is the most crucial part of the lifecycle, and the design-first process should guide each stage of the lifecycle.

Document

Help internal and external users discover, learn, and integrate with your API quickly by publishing interactive documentation, tutorials, and code samples that are always up to date. It’s important to generate comprehensive documentation that is always in sync. Help your developers discover value in your APIs faster by trying out API endpoints from within the API documentation.

Collaborate

Improve alignment and collaboration by bringing internal and external stakeholders together in a single platform through style guides, design reviews, close synchronization between internal teams, and a regular feedback loop from your users to your developers.

Govern

Improve your API program’s standardization and ability to scale by implementing proper governance and style guidelines. Govern APIs at scale with an always-in-sync, central repository of API designs, schemas, and documentation. You’ll want to build an effective governance strategy that compliments your organization's current practices with a clear view of the current state of design and documentation.
