Course Objective & Scope

APIs written by different teams under different rules drive up integration costs. This course is language- and framework-agnostic; its goal is an API design guideline that can be applied across the organisation.

Resource and URI modelling, HTTP semantics, status codes, filtering and pagination, versioning strategies, the ProblemDetails error format, idempotency keys, caching headers, OAuth2 authorisation and contract-first design with OpenAPI 3.1 are covered. Participants write an OpenAPI specification for a business domain chosen from their organisation, define lint rules with Spectral and prepare an API design checklist.

Who Should Attend?

  • Backend developers building APIs
  • Frontend and mobile developers consuming APIs
  • Integration and solution architects
  • Platform teams defining API standards
