OpenCelium 5.2

OpenCelium is an integration platform: you connect APIs, move and enrich data between them, and control the whole flow from a browser.

This documentation is organised by what you are trying to do.

New here? Start with Introduction for the ideas, then Your first workflow builds a working integration end to end. Inside the application, the guided tours do the same hands-on.

Coming from 5.1? What is new in 5.2 covers onboarding, field links, the minimap, safer deletes, multi-select and the JSON editor — and the renamed interface terms (API definition, jump, transformation).

Coming from 5.0? What is new in 5.1 covers the 5.1 editor features — jumps, debug mode, undo/redo, change history and comment boxes.

Upgrading from 4.x? Read Upgrading from 4.x first — workflows replaced connections, and two application.yml keys moved.

Looking for how to do one specific thing? The How-to guides in the sidebar are task-oriented recipes; Build a workflow is the usual entry point.

Need exact values, fields or endpoints? The Reference section has them — for example Configuration and REST API.

Running the server? See Requirements and Updating.
