Develop

This section is the handbook for building integrations on your local machine with WSO2 Integrator. Use the visual designer or write Ballerina pro-code — the two stay in sync — and look up the specific task you need: create a service, transform a payload, run a test, profile a hot path.

Where Develop ends

If your code still lives on your machine, you're in Develop. Once you push it somewhere else, move to Deploy and operate.

AI split

Tools that help you code faster (Copilot, AI test generation, AI-assisted data mapping) live here. Building AI-powered integrations (agents, RAG, MCP) belongs in GenAI.

Create and organize

Create integrations	Start new projects from the WSO2 Integrator IDE or bal new, explore samples, build libraries, or migrate from MuleSoft, TIBCO, and WSO2 MI
Understand the IDE	Get to know the Integrator app, its views, and its editors

Build

Integration artifacts	Automations, services (HTTP, GraphQL, gRPC, TCP, WebSub), event handlers (Kafka, RabbitMQ, MQTT, Salesforce, GitHub), file handlers, and supporting artifacts
Design integration logic	Visual designer, connections, control flow, error handling, expressions, query expressions, and Ballerina pro-code
Transform	Visual Data Mapper together with JSON, XML, CSV, EDI, and YAML/TOML processing

Try, test, and debug

Try and test	Built-in Try-It tool, unit testing, data-driven tests, mocking, code coverage, and AI-generated test cases
Debug	Editor debugging, remote debugging, strand dumps, and performance profiling

Tools

Integration tools	OpenAPI, GraphQL, AsyncAPI, gRPC, WSDL, XSD, EDI, and Health tools
Persist tool	bal persist — type-safe CRUD for MySQL, PostgreSQL, MSSQL, and more
Migration tools	Migrate from MuleSoft, TIBCO, or Azure Logic Apps
Scan tool	Static analysis rules for code quality

What's next

• Create a new integration — Start a project in the WSO2 Integrator IDE or from the CLI
• Design integration logic — Wire up the flow between request and response
• Deploy and operate — Ship your integration once it's ready
