Who is this presentation for?

  • Developers and architects




James Gough, Padma Sridhar, and Matthew Auburn walk you through the creation of a very simple task list API.


  • Create microservices using Spring Boot, which exposes an API (and prove that’s not the hard part, with options offered for non-Java developers)
  • Use either Pact or Spring Cloud Contract to test and progress the API with new features
  • Discover how to use OpenAPI to specify an API and the balance between developing APIs with specification first or contract driven
  • Use a specification to allow your API to be versioned and use semantic versioning to ensure that components in your architecture remain decoupled and free to move without breaking consumers
  • Explore the reasons for an API gateway, why they’re architecturally important, and the concepts of a service mesh in the context of developing an API program

Materials or downloads needed in advance

What you'll learn

  • Understand that building an API is very simple and that testing and ensuring API compatibility is key to loosely coupled services
  • Learn the importance of OpenAPI Specifications and whether they're incidental or crafted
  • Discover how to use semantic versioning to ensure compatibility of services
  • Gain an introduction to gateways and microservices
