Mastery Certified: Workflow Automation Specialist (n8n)

Shows that you can design, build, secure and operate production workflows with n8n: from choosing what to automate to running an instance with error handling, idempotent integrations, AI agents under control and tested backups. It is meant for operations engineers, developers, IT and integration specialists, and technical analysts who already know basic JavaScript and work with JSON and REST APIs. You earn it by passing the graded exam and having your final project approved.

Exam syllabus

The domains the exam covers and their weight. Open each one to see its objectives.

  1. 1Workflow fundamentals15 %
    • Assess whether a process is a good automation candidate and estimate its value and risk.
    • Explain workflows, trigger and action nodes, connections, executions, items and cluster nodes.
    • Distinguish manual executions from production executions, and drafts from published versions.
    • Choose between n8n Cloud and self-hosting, and between editions, from stated requirements.
    • Describe what the Sustainable Use License and the Enterprise License allow, and when to seek advice.
  2. 2Data and expressions20 %
    • Describe the item model (json, binary, pairedItem) and how nodes process items.
    • Write expressions for the current item, other nodes and metadata, including Luxon dates.
    • Transform data with Edit Fields, If, Switch, Filter, Merge, Split Out, Aggregate and Loop Over Items.
    • Write Code node logic in JavaScript or Python in both modes, returning valid, linked items.
    • Diagnose item linking errors and choose between expressions, data nodes and code.
  3. 3Integrations and APIs20 %
    • Configure HTTP requests: methods, credentials, headers, bodies, responses and timeouts.
    • Paginate APIs (page, offset, cursor, next URL) and respect rate limits.
    • Build webhook endpoints: test and production URLs, response modes, authentication, signatures.
    • Make integrations idempotent with idempotency keys and cross-execution deduplication.
    • Design reusable sub-workflows with explicit input contracts and caller policies.
  4. 4Error handling and reliability15 %
    • Choose node error settings: Retry On Fail, On Error and Always Output Data.
    • Build error workflows with the Error Trigger and Stop and Error, with actionable alerts.
    • Handle transient failures with backoff, and long waits with the Wait node.
    • Validate incoming data and test workflows with pinned and sample data.
    • Use executions, logs and metrics to find failing and slow steps.
  5. 5AI workflows and agents15 %
    • Assemble an AI Agent with a chat model, memory, tools and an output parser, and explain its loop.
    • Choose between a fixed workflow, an LLM chain and an agent for a task.
    • Ground answers with retrieval: loaders, splitters, embeddings and vector stores.
    • Apply guardrails, human review of tool calls and structured output validation.
    • Control AI cost and risk: iteration limits, model choice, data minimization and evaluation.
  6. 6Deployment, security and operations15 %
    • Deploy self-hosted n8n with Docker, PostgreSQL, a persistent encryption key and correct URLs.
    • Scale with queue mode and isolate code with external task runners.
    • Protect credentials and secrets: storage, sharing, environment access, hardened defaults.
    • Back up, restore and upgrade an instance safely.
    • Manage versions and environments: publishing, workflow history and Git-based source control.
