What is API Hub

API Hub is an all-in-one platform for the complete API development process. It lets you design APIs using a visual editor or code, test them automatically, create documentation, and share with users through branded portals.

The platform works with OpenAPI and AsyncAPI standards, supporting both traditional REST APIs and event-driven architectures. It includes tools for checking that your APIs follow your team's rules, generating mock servers for testing, and validating contracts between services.

Teams can work together with version control, commenting features, and role-based permissions. The platform connects with popular development tools like GitHub, CI/CD pipelines, and API management systems. Whether you need basic API design or complex enterprise workflows, API Hub provides the features you need.

How to Use API Hub

Getting started with API Hub is simple. Here are the steps:

  • Create an account at swagger.io and choose your plan based on your needs.

  • Start designing your API using the editor. You can use the visual form-based editor if you prefer not to write code, or use the code editor for full control.

  • Apply style guides and templates to ensure your API follows standards. The platform will check your design automatically and show any issues.

  • Generate mock servers to test your API before building it. This lets you try out the API and get feedback early.

  • Set up contract tests to validate that different parts of your system work together correctly.

  • Create automated tests for your API endpoints and connect them to your deployment pipeline.

  • Publish your API documentation to a branded portal where users can discover and learn about your API.

  • Use team collaboration features like comments and version control to work with others efficiently.

FAQ's About API Hub

What is the difference between API Hub and the free Swagger tools?
API Hub (formerly SwaggerHub) is a commercial platform that includes the free Swagger tools plus many additional features. While free Swagger tools provide basic API design and documentation, API Hub adds team collaboration, version control, automated testing, contract validation, branded portals, AI assistance, and enterprise-grade features. The free tools work well for individual projects, but API Hub is built for team workflows and professional API management.
Can API Hub work with both REST APIs and event-driven APIs?
Yes, API Hub supports both OpenAPI specification for REST APIs and AsyncAPI specification for event-driven and message-based APIs. This makes it flexible for modern architectures that combine traditional request-response patterns with asynchronous messaging, webhooks, and streaming data. You can design, document, and test both types in the same platform.
How does contract testing work in API Hub?
Contract testing in API Hub validates that different services in your system work together correctly. It checks both the provider side (the API being called) and the consumer side (the application calling the API) to ensure they agree on the contract. The platform uses AI to help automate test creation and can run these tests in your deployment pipeline to catch breaking changes before they reach production.
Can I customize the API portal with my company branding?
Yes, API Hub lets you create fully branded API portals with custom domains, landing pages, logos, and styling. You can control which APIs are public or private, organize them into products, and create a professional developer experience. The Portal Pro add-on provides even more customization options and access management features for teams that need advanced branding capabilities.
Does API Hub integrate with our existing development tools?
Yes, API Hub integrates with many popular development tools. It connects with version control systems like GitHub and GitLab, CI/CD platforms like Jenkins, API gateways, and testing frameworks. You can trigger tests automatically in your pipeline, sync API definitions with your code repository, and export designs in multiple formats. The platform also provides APIs and CLI tools for custom integrations.
