n8n – process automation and system integration in practice

Training process

Training needs analysis

If you have specific requirements regarding the training programme, we will carry out a training needs analysis for you. This will guide us on which aspects of the programme should receive greater emphasis, so that the training programme meets your specific needs.

What will you gain?

Connect systems with confidence - You will learn how to build workflows that connect APIs, chat tools, spreadsheets, databases, and team apps, so you can integrate scattered business processes much faster and with less manual work.

Build workflows on your own - You will go from a first trigger to a complete flow with field mapping, comments, and versioning, so after the course you can create working automations on your own without trial and error.

Launch webhook-based automations - You will learn how to design webhooks, schedules, and event-driven integrations, so your processes can start automatically on time, on an HTTP request, or from an external system signal.

Master data mapping - You will learn how to read JSON structures, work with items, write expressions, and handle files, CSV, XML, and API pagination, so you can process even complex input data correctly.

Extend n8n with code - You will use the Code node for validation, aggregation, and custom transformations, which gives you the flexibility to handle cases where standard nodes are not enough for your process logic.

Create resilient automations - You will learn to implement retries, error handling, alerts, deduplication, and idempotency, so your workflows stay more stable and safer even when external services fail or slow down.

Add AI to your workflows - You will see how to use OpenAI or Azure OpenAI for classification, summarization, and data extraction, so you can enrich content, respond to requests, and moderate information automatically.

Prepare for production rollout - You will learn how to handle credentials, environments, workflow export, Git, Queue Mode, and backups, so you can set up n8n for secure, maintainable use in a real production setting.

What are the prerequisites for participating in the training?

Basic web app skills - You should be comfortable using a browser, forms, and admin panels, so you can work smoothly in the n8n editor and test connections with external services.

Understanding data fields - You should understand records, fields, and basic data formats, so you can map information between systems more easily and read API or database responses with confidence.

API integration basics - You should know the basics of working with APIs, including requests, responses, headers, and authentication, so you can configure HTTP Request nodes and webhooks consciously.

Basic logic and JavaScript - You should know the basics of conditions, variables, and simple JavaScript snippets, so it is easier for you to understand expressions, work in the Code node, and debug flows.
