Quick Expressions

Instead of manual clicking, simply hit the equals sign (=) on your keyboard while inside a fixed value field. This instantly toggles the field to an expression mode.

Move Between Nodes

You do not need to click out of every panel. Move your mouse to the left or right edges of the screen to cycle through configuration panels, or use arrow keys to select nodes and press Enter to open them.

Deactivate Nodes

Testing often requires bypassing certain steps. Hover over any node and press D to deactivate or reactivate it instantly.

Quick Add Node

To add a new node without searching through the sidebar, press the Tab key anywhere on the workflow canvas to pull up the node search menu.

Pin Data

Press P to pin the output of a node. This is especially useful for expensive or slow API calls. Once pinned, you can test the rest of the workflow repeatedly without making new external requests.

Mock Data

Click the pencil icon on a trigger or node to manually enter mock data. This allows you to simulate incoming information and test subsequent nodes without triggering the actual event.

View Sub-Execution Data

When using sub-workflows, click "View Sub-Execution" to see the specific input and output of that run. This is the fastest way to identify exactly where a sub-process is failing.

Copy to Editor

While reviewing previous executions, use the "Copy to Editor" button. This brings live data from a past run into your current workspace, making it easier to map fields and debug with real-world variables.

Error Workflows

Create a separate workflow using the "Error Trigger." This native node automatically notifies you via email or Slack whenever a main workflow fails, ensuring you never miss a breakdown.

Continue On Error

By default, n8n stops a workflow if a node fails. Change this in the node settings to "Continue On Error" to ensure that one bad item in a batch (like a 404 error) doesn't kill the entire automation.

Error Output Branching

You can enable "Error Output" to create a dedicated branch for failed items. This allows you to handle successes and failures differently within the same canvas.

Node-Specific Settings

Explore individual node settings for toggles like "Execute Once" (to prevent loops), "Always Output Data," and "Retry On Fail."

Remove n8n Attributions

In nodes like Slack, Telegram, or Email, turn off "Append attribution" to remove the "This message was sent by n8n" footer.

Agent Logs

Check the Agent Logs to see the "thinking" process of your AI. This reveals the system prompts used and the specific data passed to its tools.

Human in the Loop

Use the "Wait for Approval" node to pause an automation. The workflow will only continue once a human interacts with an approval button or form sent to Slack or Email.

Standardize Inputs

If you are using multiple channels (like WhatsApp and Discord) to trigger the same AI, use a "Set" node to map different input names into a single, standardized field.

Structured AI Outputs

Toggle "Require Specific Output" for AI agents and use a Structured Output Parser. This forces the AI to return data as a valid JSON object rather than plain text.

Current Date and Time

Use

{{ $now }}

.format()

Workflow Variables

Access variables to get context like the Execution ID, Workflow Name, or the active status of the current build.

Specify Inputs for Sub-Workflows

Instead of using an "Accept All" trigger, define exact fields (e.g., Name, Email). This makes mapping much cleaner in the parent workflow.

Array .join() Function

Use

.join(", ")

.join("\
")

.replace() Function

Use the JavaScript

.replace()

Sticky Notes and Formatting

Press Shift + S to add sticky notes. You can use Markdown to create headers and bold text, making your logic easier for teammates to understand.

Workflow History

Click the clock icon to access version history. You can restore, clone, or download previous versions if a new change breaks your build.

Saved API Credentials

Never paste API keys directly into nodes. Use the "Credentials" system to store keys securely. This allows you to share workflow templates without exposing your private data.
