Design for international use.
As simple as possible, but no simpler.
Avoid dependency on specific technologies.
Use REST / Don’t break the web.

Follow existing standards, best practices, when possible.

What is API system design?

API design refers to the process of developing application programming interfaces (APIs) that expose data and application functionality for use by developers and users. APIs are important to modern organizations, adding new capabilities to everything from their operations and products to their partnership strategies.

What is API first design approach?

API first is an approach to development in which your APIs are considered first-class citizens. This means that everything you’re developing is developed with the end goal of API consumption in mind. In API first development, APIs are no longer an afterthought — they’re a differentiator.

What is REST API what are the principles of REST API?

An API, or application programming interface, is a set of rules that define how applications or devices can connect to and communicate with each other. A REST API is an API that conforms to the design principles of the REST, or representational state transfer architectural style.

How do I approach API design?

An API-first approach involves developing APIs that are consistent and reusable, which can be accomplished by using an API description language to establish a contract for how the API is supposed to behave. Establishing a contract involves spending more time thinking about the design of an API.

What is API architecture diagram?

API architecture refers to the process of developing a software interface that exposes backend data and application functionality for use in new applications. With an API-first architecture, you can create ecosystems of applications that are modular and reusable — which is ideal for microservices.

What are the layers of API?

See below:

Level 1: Isolated Applications.
Level 2: Unstructured Integrations.
Level 3: Component-based Architectures.
Level 4: Service-oriented Architectures.
Level 5: Private APIs based on Microservice Architectures.
Level 6: Open APIs.
Level 7: APIs as Business.

How can I design better APIs?

Here are some specific recommendations to ease and facilitate adoption of your API:

Make sure people can actually use your API and that it works the first time, every time.
Keep it simple.
Provide language-specific libraries to interface with your service.
Simplify any necessary signup.
Provide excellent support.

How would you design an API?

Best practices for REST API design

Accept and respond with JSON.
Use nouns instead of verbs in endpoint paths.
Name collections with plural nouns.
Nesting resources for hierarchical objects.
Handle errors gracefully and return standard error codes.
Allow filtering, sorting, and pagination.
Maintain Good Security Practices.

How does API work diagram?

What is an API Diagram? An API diagram documents the routines and protocols of an API to clarify its structure and behavior. API diagrams are helpful because they quickly show both developers and non-technical stakeholders like product managers understand how the system will behave.
