Description

Introduction

WebMethods Flow Services Development training is designed to provide hands-on expertise in building, configuring, and managing integration logic using Flow language in the webMethods Integration Server.

This course focuses on creating reusable, scalable, and maintainable services using Flow steps, built-in services, pipelines, error handling, and debugging techniques. Participants will learn how to design end-to-end integration flows that connect applications, services, and systems efficiently.

By the end of this training, learners will be able to confidently develop, test, and deploy Flow Services as part of enterprise-grade integration solutions.

Prerequisites

1. Basic understanding of webMethods Integration Server architecture
2. Familiarity with webMethods Designer
3. Knowledge of integration concepts (services, adapters, messaging)
4. Basic understanding of XML, JSON, and data mapping
5. General programming or workflow logic experience (recommended, not mandatory)
