Workflow Templates

This n8n template provides a simple yet powerful utility for validating if a given string input is a valid JSON format. You can use this to pre-validate data received from external sources, ensure data integrity before further processing, or provide immediate feedback to users submitting JSON strings. 🔧 How it works Webhook: This node acts as the entry point for the workflow, listening for incoming POST requests. It expects a JSON body with a single property: jsonString: The string that you want to validate as JSON. Code (JSON Validator): This node contains custom JavaScript code that attempts to parse the jsonString provided in the webhook body. If the jsonString can be successfully parsed, it means it's valid JSON, and the node returns an item with valid: true. If parsing fails, it catches the error and returns an item with valid: false and the specific error message. This logic is applied to each item passed through the node, ensuring all inputs are validated. Respond to Webhook: This node sends the validation result (either valid: true or valid: false with an error message) back to the service that initiated the webhook request. 👤 Who is it for? This workflow is ideal for: Developers & Integrators: Pre-validate JSON payloads from external systems (APIs, webhooks) before processing them in your workflows, preventing errors. Data Engineers: Ensure the integrity of JSON data before storing it in databases or data lakes. API Builders: Offer a dedicated endpoint for clients to test their JSON strings for validity. Customer Support Teams: Quickly check user-provided JSON configurations for errors. Anyone handling JSON data: A quick and easy way to programmatically check JSON string correctness without writing custom code in every application. 📑 Data Structure When you trigger the webhook, send a POST request with a JSON body structured as follows: { "jsonString": "{\"name\": \"n8n\", \"type\": \"workflow\"}" } Example of an invalid JSON string: { "jsonString": "{name: \"n8n\"}" // Missing quotes around 'name' } The workflow will return a JSON response indicating validity: For a valid JSON string: { "valid": true } For an invalid JSON string: { "valid": false, "error": "Unexpected token 'n', \"{name: \"n8n\"}\" is not valid JSON" } ⚙️ Setup Instructions Import Workflow: In your n8n editor, click "Import from JSON" and paste the provided workflow JSON. Configure Webhook Path: Double-click the Webhook node. In the 'Path' field, set a unique and descriptive path (e.g., /validate-json). Activate Workflow: Save and activate the workflow. 📝 Tips This JSON validator workflow is a solid starting point. Consider these enhancements: Enhanced Error Feedback: Upgrade: Add a Set node after the Code node to format the error message into a more user-friendly string before responding. Leverage: Make it easier for the caller to understand the issue. Logging Invalid Inputs: Upgrade: After the Code node, add an IF node to check if valid is false. If so, branch to a node that logs the invalid jsonString and error to a Google Sheet, database, or a logging service. Leverage: Track common invalid inputs for debugging or improvement. Transforming Valid JSON: Upgrade: If the JSON is valid, you could add another Function node to parse the jsonString and then operate on the parsed JSON data directly within the workflow. Leverage: Use this validator as the first step in a larger workflow that processes JSON data. Asynchronous Validation: Upgrade: For very large JSON strings or high-volume requests, consider using a separate queueing mechanism (e.g., RabbitMQ, SQS) and an asynchronous response pattern. Leverage: Prevent webhook timeouts and improve system responsiveness.

TinyURL Shortener via Webhook

by ist00dent

This n8n template allows you to automatically create shortened URLs using the TinyURL API by simply sending a webhook request. It's a quick and efficient way to integrate URL shortening into your automated workflows, ideal for sharing long links in social media, emails, or other applications. 🔧 How it works Receive Link Webhook: This node acts as the entry point for the workflow. It listens for incoming POST requests and expects a JSON body containing the url to be shortened and your api_key for TinyURL. Create TinyURL: This node sends a POST request to the TinyURL API, passing the long URL and your API key. It can also accept optional parameters like domain, alias, and description to customize the shortened link. Respond with Shortened URL: This node sends the response from the TinyURL API (which includes the new shortened URL) back to the service that initiated the webhook. 👤 Who is it for? This workflow is ideal for: Content Managers & Marketers: Quickly shorten links for campaigns, social media posts, or tracking. Developers: Automate the process of link shortening within applications or scripts. Automation Enthusiasts: Integrate a URL shortener into various n8n workflows (e.g., after generating a report, before sending a notification). Anyone needing on-demand short links: A flexible solution for ad-hoc link shortening. 📑 Data Structure When you trigger the webhook, send a POST request with a JSON body structured as follows: { "api_key": "YOUR_TINYURL_API_KEY", "url": "https://www.verylongwebsite.com/path/to/specific/page?param1=value1&param2=value2", "domain": "tinyurl.com", // Optional: defaults to tinyurl.com "alias": "myCustomAlias", // Optional: desired custom alias for the link "description": "My project link" // Optional: description for the link } The workflow will return the JSON response directly from the TinyURL API, which will include the short_url and other details about the newly created link. ⚙️ Setup Instructions Obtain TinyURL API Key: Before importing, make sure you have an API key from TinyURL. You can typically get this by signing up for an account on their website. Import Workflow: In your n8n editor, click "Import from JSON" and paste the provided workflow JSON. Configure Webhook Path: Double-click the Receive Link Webhook node. In the 'Path' field, set a unique and descriptive path (e.g., /shorten-link). Activate Workflow: Save and activate the workflow. 📝 Tips Dynamic Inputs: The workflow is set up to dynamically use the url, api_key, alias, and description from the incoming webhook data. This makes it highly flexible. Error Handling: You can add an Error Trigger node to catch any issues (e.g., invalid API key, malformed URL) during the TinyURL creation process. Configure it to send notifications or log errors for easy troubleshooting. Post-Shortening Actions: After generating the shortened URL, you can insert additional nodes before the Respond with Shortened URL node to perform other actions. For example, you could: Save to a Database: Store the original and shortened URLs in a database like Airtable, Google Sheets, or a PostgreSQL database. Send a Message: Automatically send the shortened URL via Slack, Discord, email, or SMS. Update a Record: Update a CRM record or project management task with the new shortened link. Custom Domains: If you have a custom domain configured with your TinyURL account, you can change the domain parameter in the Create TinyURL node to use it.

Multi-service Terminal: Access Gmail, X, Telegram & News with Gemini AI

by Roni Bandini

This workflow receives plain English instructions from a retro console via a webhook. Using an AI agent, it can combine multiple tools to read general RSS news headlines, stock market updates, emails, calendar events, search X, send Telegram messages, and run Linux commands. The idea is to avoid using smartphones or regular laptops in the morning, and instead use a retro console installed on an old notebook or netbook. You will need to copy a Python script onto the notebook, configure the webhook URL, and set up all the required credentials. Steps: Setup Gemini API key, Google Gmail and Calendar credentials from console.google.com Setup X credentials, RSS URL, etc Obtain the webhook URL and paste into the Python code to be executed at the Linux machine Run the python script with python3 console.py Note: if you ask for a Linux command, the command will not only be returned but also executed.

Location-Based Triggered Reminder via Telegram Bot (iOS)

by Roninimous

This workflow integrates iOS Shortcuts with n8n to create a simple, automatic location-based reminder system. When the user arrives at a specified location, an automation in the Shortcuts app sends a webhook trigger to n8n. If the trigger matches predefined date and time conditions, n8n sends a Telegram message reminder to the user. This is perfect for repetitive weekly tasks like taking out the bins, customized with conditions for day and time. Key Features Location-Based Trigger: Uses iOS Shortcuts automation to start the workflow upon arrival at a specific location. Time and Day Validation: Logic in n8n checks current weekday and time to ensure reminders are sent only when appropriate. Telegram Integration: Sends reminders directly to your Telegram account using your bot. Minimal Setup: Uses native iOS and simple webhook setup in n8n. How It Works iOS Shortcut Trigger: When the user arrives at a designated location, the iOS shortcut sends a GET request to the n8n webhook. n8n Webhook Node: Receives the request and triggers the workflow. Conditional Check: An IF node checks if the current time is after 4:00 PM and it's a Wednesday (or any other configured condition). Telegram Node: If the condition passes, n8n sends a message like "Don't forget to take the bins out." to your Telegram bot. Setup Instructions Create a Telegram Bot: Use @BotFather to create a bot and obtain your bot token. Add Telegram API credentials in n8n with your bot token. Setup iOS Shortcut: Open the Shortcuts app on your iPhone. Go to the Automation tab → Tap + → Create Personal Automation. Choose Arrive → Select a location. Add action: Get Contents of URL. Method: GET, URL: your n8n Webhook URL (e.g. https://n8n.yourdomain.com/webhook/your-path). Save the automation. (You can also test the automation by pressing the Play button) Import Workflow into n8n: Load the provided workflow JSON. Set your webhook path and Telegram credentials. Adjust the logic in the IF node to your usecase. In my case, I check if today is Wednesday and after 4 PM until Midnight. Expose n8n Publicly: Ensure your n8n instance is publicly accessible via HTTPS so the shortcut can reach it. Customization Guidance Change Reminder Message: Modify the text inside the Telegram node to suit different reminders. Add More Conditions: Extend the logic to support more days, hours, or different trigger messages. Add Multi-Channel Output: Send reminders via email, SMS, or Slack in addition to Telegram. Use More Triggers: Expand to other types of shortcut triggers (e.g. NFC tag, leaving location, time of day). Security and Implementation Webhook Protection: Avoid using easily guessable webhook URLs. Secure Telegram Token: Store your bot token securely in n8n credentials, not in plain workflow text. Limit Shortcut Scope: Only trigger the shortcut at trusted locations or with secure iCloud sync. Automation Permissions: Ensure your iPhone allows shortcut automations to run without confirmation. Benefits Automates repetitive location-based reminders without user interaction. Provides a lightweight, native solution using iOS and n8n with no extra apps. Keeps you on track for routine tasks like garbage days, medicine reminders, or arrival-based tasks. Easily extendable for multiple locations or trigger conditions.
