Expose Library API using API Manager | Full Setup with Swagger, Mock Files & Sandbox Key Demo

Описание: Build and Expose Library APIs using API Manager and API Mocker — step-by-step!
In this video, you’ll learn how to configure mock APIs, integrate Swagger, deploy on API Manager, test Sandbox keys, and manage end-to-end API exposure.

This tutorial covers:
📘 Create mock API definitions in config.json
📘 Build and test /library/books, /library/book/borrow, /library/book/status, /library/book/return, /library/book/close
📘 Configure Swagger for Library APIs
📘 Deploy & Expose Library API in API Manager
📘 Generate and test Sandbox keys
📘 Subscribe and test /police/fir/* APIs for multi-domain integration

By the end, you’ll have a fully working Library API setup ready to expose securely through API Manager — great for demos, learning, and interviews.

✅ What You’ll Learn:

✅ Setting up your API endpoints with API Mocker
✅ Adding mock responses for /library/books, /borrow, /status, /return, /close
✅ Creating Swagger/OpenAPI definitions for documentation
✅ Exposing APIs through API Manager and configuring access control
✅ Testing APIs using Sandbox keys for secure access
✅ Subscribing and managing API consumers
✅ Integrating multiple APIs (Library + Police FIR) to showcase real-world scenarios

🎯 Key Highlights:

Create realistic mock JSON responses
Define and configure mock API endpoints in config.json
Integrate Swagger with API Manager for easy documentation and testing
Expose your API securely using Sandbox keys
Deploy and verify each API in API Manager
Learn API subscription, testing, and exposure end-to-end
