How to Use

[{"step":"Define your workflow goal","action":"Use the prompt template to specify the trigger, actions, and integrations needed. Replace [PLACEHOLDERS] with your specific requirements (e.g., 'Send an email via Gmail when a new row is added to Google Sheets').","tip":"Start with a simple workflow and expand it incrementally. Use n8n’s built-in node documentation to understand available integrations."},{"step":"Generate the workflow JSON","action":"Paste the prompt into an AI assistant (e.g., Claude Desktop) and run it. The AI will return a complete n8n workflow in JSON format, including nodes, parameters, and connections.","tip":"Ask the AI to include error handling and logging for robustness. Specify any custom formatting or API parameters required for your use case."},{"step":"Import and configure in n8n","action":"Open n8n, create a new workflow, and import the generated JSON. Configure credentials for each node (e.g., Slack, Google Sheets, or API keys) and test the connection.","tip":"Use n8n’s 'Test Node' feature to verify each step works before activating the workflow. Save versions of your workflows to track changes."},{"step":"Deploy and monitor","action":"Activate the workflow and monitor its execution via n8n’s execution logs. Adjust nodes or triggers as needed based on real-world usage.","tip":"Set up notifications (e.g., email or Slack) for workflow failures. Use n8n’s 'Schedule Trigger' node for time-based automation."},{"step":"Iterate and expand","action":"Refine the workflow based on feedback or new requirements. Add conditional logic, parallel branches, or additional integrations (e.g., databases, CRM systems) to enhance functionality.","tip":"Leverage n8n’s community nodes or custom code nodes for advanced use cases. Document your workflows for team collaboration."}]

Usage Examples

Prompt Template

Build an n8n workflow in [LANGUAGE] that [ACTION] when [TRIGGER] occurs. Include these steps: [STEP_1], [STEP_2], and [STEP_3]. Use [API_SERVICE] for [FUNCTION]. The workflow should handle errors by [ERROR_HANDLING]. Deploy it to n8n with [DEPLOYMENT_METHOD].

Example Output

Here’s a complete n8n workflow in JSON format for automating Slack notifications when new GitHub issues labeled 'urgent' are created. The workflow triggers on GitHub webhooks, filters issues by label, formats a Slack message with issue details, and posts it to a designated channel. It includes error handling for failed API calls and is deployed via n8n’s web interface.
