About this course
This course develops practical capability in REST API Development. Its course-specific content covers HTTP semantics, Contract design, Access and errors, API validation, followed by an applied project focused on design and implement a versioned resource api. The lessons include concrete configuration, design, testing or operational decisions appropriate to the subject.
Who this is for
Administrators, developers and practitioners who work with REST API Development or plan to take on responsibilities in this area.
Before you start
Basic computer literacy and a foundational understanding of web development. Prior experience with the named product helps with the practical exercises.
Design and implement a versioned resource API
Deliver design and implement a versioned resource api. Use the module outcomes to state requirements, demonstrate a working result, test an expected failure or boundary case, and document assumptions and follow-up work.
Course content
Course-specific syllabus and practical exercises. Lab release, access arrangements and final delivery scope are confirmed before enrolment.

+
- Resources, methods and status codes
- Idempotency and safe retry behaviour
Practical exerciseApply http semantics to the design and implement a versioned resource api and capture the validation evidence.
02Contract design
+
- Resource schemas and validation
- Pagination, filtering and version strategy
Practical exerciseApply contract design to the design and implement a versioned resource api and capture the validation evidence.
03Access and errors
+
- Authentication and object-level authorisation
- Consistent errors and rate-limit behaviour
Practical exerciseApply access and errors to the design and implement a versioned resource api and capture the validation evidence.
04API validation
+
- OpenAPI examples and contract tests
