Working with the Loop Over Items Node in n8n

Automating complex workflows often requires handling lists of records, batching API calls, and processing items individually without breaking your execution flow. This text-based guide teaches you how to master the Loop Over Items node in n8n to manage data sets with precision. You will begin with fundamental workflow concepts and data structures before diving into step-by-step written tutorials that show you how to configure loops, handle batches, and aggregate outputs. What you'll learn: - Understand core n8n terminology, data structures, and how arrays flow between nodes - Configure the Loop Over Items node for single-item and custom batch-size iterations - Manage pagination and iterative API requests efficiently - Apply robust error-handling techniques inside iterative execution paths - Aggregate processed items back into unified data payloads for downstream nodes - Structure clean, maintainable automation architectures that avoid rate limits The course begins with foundational concepts and workflow syntax, progresses through realistic data iteration scenarios with clear text explanations and code examples, and concludes with architectural best practices for production workflows. This course is designed for beginners and automation enthusiasts who want to gain confidence handling complex data loops in n8n. No prior coding experience is required.
