To create your first workflow, access the n8n interface, click “Create new workflow,” add a trigger node (such as a manual trigger or scheduled trigger), connect additional nodes for actions, configure each node’s parameters, and then save and activate the workflow.
n8n Core Concepts
11. What is a node in n8n?
A node in n8n is a building block representing either a trigger event, an action to perform, or a service integration. Nodes are connected together to form workflows, with each node processing data and passing it to the next node in the sequence.
12. What is the difference between trigger and regular nodes?
Trigger nodes start workflows based on events (like webhook calls, schedules, or external service events), while regular nodes perform actions or transformations on data within an already-running workflow. Workflows must begin with at least one trigger node.
13. How do connections between nodes work?
Connections in n8n are represented by lines between nodes, showing the flow of data. Each connection transfers the output data from one node to become the input data of the next node, allowing for sequential processing of information through the workflow.
14. What are credentials in n8n?
Credentials in n8n securely store authentication information for connecting to external services. They’re created once and can be reused across multiple workflows and nodes, keeping sensitive information like API keys and passwords separate from workflow definitions.
15. How does data flow through an n8n workflow?
Data in n8n flows as JSON objects between nodes. Each node receives input data, processes it according to its configuration, and outputs transformed data to the next node. This data-centric approach allows for complex transformations and integrations across services.
Workflow Development
16. What are the main types of trigger nodes in n8n?
Main trigger types include webhooks (HTTP requests), scheduled triggers (time-based), polling triggers (checking for changes), and service-specific triggers (responding to events from integrated platforms like Gmail, Slack, or database systems).
17. How do I schedule workflows in n8n?
Workflows are scheduled using the “Cron” trigger node, which allows for expression-based scheduling (like 0 * * * * for hourly execution) or through the Schedule trigger with more user-friendly interval options such as “every hour” or “every Monday at 9 AM.”
18. How can I test nodes during workflow development?
Nodes can be tested by clicking the “Execute” button on a selected node, which processes only that node and any predecessors. This allows checking intermediate results without running the entire workflow, making debugging and development more efficient.
19. What is n8n’s Expression Editor?
The Expression Editor is a powerful feature for creating dynamic values in node parameters. It allows using JavaScript-like expressions surrounded by double curly braces {{ }} to reference data from previous nodes, perform calculations, or manipulate strings.
20. How do I handle errors in n8n workflows?
Error handling in n8n can be managed through the “Error Workflow” setting (which executes a separate workflow on errors), using IF nodes to check for error conditions, implementing try/catch in Function nodes, and setting up monitoring with notification nodes for critical workflows. Find error handling best practices at CloudRank.
Working with Data
21. What data formats does n8n support?
n8n primarily works with JSON data but can process various formats through specific nodes. It can handle CSV, XML, HTML, binary data (like files and images), and can convert between formats using specialized nodes like CSV Parse, XML, and Data Transformation nodes.
22. How can I transform data between nodes?
Data transformation options include the Function node (for custom JavaScript transformations), Set node (for mapping fields), Move Binary Data node, Split In Batches node, Merge node, and Item Lists node. These provide flexibility for reshaping data to match target service requirements.
23. What is the Function node and how is it used?
The Function node allows writing custom JavaScript code to process workflow data. It receives input items and can return transformed items, enabling complex operations like conditional logic, data formatting, mathematical calculations, and custom algorithms not available in standard nodes.
24. How do I work with JSON in n8n?
JSON handling in n8n is native, as all data between nodes is JSON. Specific JSON operations can be performed using the Function node with JavaScript methods, the JSON Parse node (converting strings to objects), JSON Stringify node (for the reverse), and Item Lists node for array manipulations.
25. How can I filter data in workflows?
Data filtering can be accomplished using the IF node (for conditional branching based on criteria), the Filter node (which passes only items matching conditions), or through custom filtering logic in Function nodes (returning only desired items from arrays).
Integration Capabilities
26. How many integrations does n8n offer?
n8n offers 300+ native integrations (nodes) for popular services and platforms, with new nodes added regularly. Additionally, generic nodes like HTTP Request, Webhook, and Function allow connecting to virtually any service with an API, extending n8n’s integration possibilities.
