n8n によるワークフロー自動化入門

Start automating with n8n—the open-source workflow automation platform. Learn what makes n8n unique among no-code tools, explore its drag-and-drop canvas, and master triggers, nodes, and connections. By chapter's end you'll build complete workflows that capture form data, call external APIs, and transform outputs with Edit Fields.

Add decision-making power to your n8n workflows. Use If and Switch nodes to branch logic based on conditions, write expressions to access and reshape dynamic data, flatten nested JSON structures, and merge multiple datasets into a single unified output—all without writing code.

Supercharge your automations with AI. Connect OpenAI-powered Agent nodes to your n8n workflows, craft prompts that classify and summarize text, route outputs through conditional branches, and build end-to-end pipelines that collect form input, enrich it with LLM intelligence, and deliver personalized results—no code required.
