Developer docs

Four ways to drive Etlworks programmatically: from a REST call to a custom AI subagent. Pick the entry point that fits your stack.

REST API

534 documented endpoints in 46 groups: flows, executions, connections, schedules, Integration Agents, users, metrics, administration, and more. JWT or API-key auth, JSON throughout. The platform's primary integration surface.

AI Agent API

Drive Simba (the Etlworks AI agent) from your own AI stack over REST, or connect any MCP client (Cursor, Claude Desktop, ChatGPT) natively. Direct tool access, full agent chat, multi-turn sessions, SSE streaming. Use as a subagent in LangChain, CrewAI, AutoGen.

CLI

172 commands across flows, connections, schedules, on-prem agents, and inline SQL. Built into the Etlworks UI plus a single REST endpoint for automation. Capture variables, control structures, parallel execution, redirects.

Scripting

JavaScript (Nashorn) and Python 3.13 (GraalPy) inside Mapping, transformations, validation, conditions, and custom flows. Direct access to Java APIs. 25+ recipes ported from production.
