Description

Introduction

In today’s integration-driven digital landscape, APIs form the backbone of enterprise connectivity. webMethods provides a powerful, secure, and scalable platform for building, exposing, and managing both RESTful and SOAP-based APIs.

This training is designed to give participants hands-on, practical experience in designing, developing, testing, and securing REST and SOAP APIs using webMethods Integration Server, Designer, and related components. Participants will learn industry best practices for API design, error handling, security, versioning, and performance optimization.

By the end of this course, learners will be able to confidently build enterprise-grade APIs and integrate heterogeneous systems using webMethods.
