What are triggers and can you provide some examples?

Triggers are the starting points of an N8N workflow. They define the event that will initiate the automation. Examples include:

• Manual Trigger: Runs the workflow when a "Test Workflow" button is clicked within N8N, useful for initial testing and simple tasks.
• On App Event: Initiates a workflow when a specific event occurs in a connected application (e.g., a new row is added to an Airtable, a new email is received in Gmail, a booking is created in Cal.com). N8N boasts hundreds of native integrations for this type of trigger.
• On Schedule: Triggers a workflow to run at predefined intervals (e.g., every day, every hour, or using a custom cron expression).
• Webhook Call: Allows you to set up a unique URL that, when accessed or receives data, can trigger a workflow. This enables integration with platforms that don't have native N8N support.
• On Form Submission: Starts a workflow when a user submits data through a form created directly within N8N.

What are actions and how do they work with triggers in a workflow?

Actions are the tasks that your N8N workflow performs after being initiated by a trigger. Once a trigger event occurs, the workflow proceeds to execute the connected action nodes in a defined sequence. Each action node interacts with a specific application or performs a particular operation. For example, after a form submission trigger, an action could be to send an email using Gmail, create a task in ClickUp, or send data to an AI model for processing. Data from the trigger (or previous action nodes) is passed into the subsequent action nodes for processing and manipulation.

How are connections to external applications managed in N8N?

N8N uses credentials to securely connect to various software platforms and apps. When adding an action that requires connecting to an external service (like Gmail or ClickUp), you'll be prompted to either select an existing credential or create a new one. Credential creation often involves using OAuth 2.0, where you authorise N8N to access your account with the service (e.g., "Sign in with Google"). For services that don't support OAuth 2.0, you might need to provide an API key, which you typically generate within the settings of the external application. N8N provides documentation to guide you through the credential creation process for different services. Once a credential is created, it can be reused across multiple workflows.

How can you test and troubleshoot workflows in N8N during development?

N8N offers several ways to test and troubleshoot workflows:

• Test Step: For individual nodes, you can click "Test Step" to execute that specific node using either pinned data from a previous execution or by providing new test data. This allows you to see the input and output of each step in isolation.
• Test Workflow: This option runs the entire workflow from the trigger point using either previously pinned data or by prompting a trigger event (e.g., submitting a test form, triggering a webhook). This allows you to see the flow of data through all the connected nodes.
• Pinning Data: After a successful test execution of a node, you can "pin" the output data. This pinned data can then be used as sample input for subsequent nodes, making testing and development more efficient as you don't need to re-trigger the entire workflow or re-enter data repeatedly.
• Output Inspection: Each node displays its input and output data in various formats (Table, JSON, Schema), allowing you to examine the data being passed between steps and identify any issues or incorrect data transformations.
• AI Assistant: The built-in AI assistant can help diagnose issues by analysing the workflow and drawing on community knowledge to provide potential solutions.
