Description

Introduction

APIs are the backbone of modern digital integration. This training provides a comprehensive, hands-on understanding of how to design, build, secure, publish, manage, and govern APIs using webMethods.

Participants will learn industry-standard API design best practices, understand the complete API lifecycle, and gain practical experience using webMethods API Gateway, Integration Server, and Developer Portal. The course emphasizes real-world enterprise use cases, governance models, and lifecycle automation.

By the end of this training, learners will be able to design scalable APIs, manage versions effectively, enforce security and policies, and monitor APIs across their entire lifecycle.

Prerequisites

2. Familiarity with REST and SOAP concepts
3. Knowledge of HTTP, JSON, XML
4. Basic API consumption experience (Postman or similar tools)
5. Awareness of enterprise integration concepts (recommended, not mandatory)
