RestAPI

Practical training in designing and implementing REST APIs for modern web applications. The program covers REST conventions, working with JSON, API testing and security mechanisms. The workshop focuses on building real services from requirements through design to implementation. The workshop methodology provides direct experience in creating and integrating REST compliant APIs.

Issues

REST architecture
HTTP methods (GET, POST, PUT, DELETE).
CRUD to HTTP mapping
JSON format
URL path construction
Passing parameters
HTTP status codes
HTTP headers
Representation of business facilities
Authentication mechanisms
Testing with cURL
Documenting the API

This training is part of the path:

Software Tester / QA Engineer

Benefits
