1.1 Workflow description

Title: Check for preview for a link
Workflow name: Check for preview for a link

This workflow allows you to check for preview for a link and return the preview if it exists.

Peekalink node: This node checks if a preview is available for a URL or not. If a preivew is available the node returns true, otherwise false.

IF node: The IF node checks the output from the previous node. If the condition is true the node connected to the true branch is executed. If the condition is false the node connected to the false branch is executed.

Peekalink1 node: This node will fetch the preview of the URL. Based on your use-case, you can connect the Slack node, Mattermost node etc. to get the response on these platforms.

NoOp node: Adding this node here is optional, as the absence of this node won't make a difference to the functioning of the workflow. We've added this as it can sometimes help others with a better understanding of the workflow, visually.

4. Reproducing the Workflow from Scratch

1. Download the workflow JSON

Use the JSON export at /data/workflows/935/935.json as the source template for this automation.
2. Import the template into n8n

Open n8n, import the downloaded JSON, and review each node before activating the workflow.
3. Configure credentials and variables

Replace placeholder credentials, API keys, webhook URLs, account IDs, and environment-specific values with your own settings.
4. Test with sample data

Run the workflow manually or in a staging workspace, inspect node output, and confirm downstream systems receive the expected data.
5. Activate and monitor

Enable the workflow only after testing, then monitor executions, errors, and rate limits during the first production runs.

5. General Notes & Resources

Review imported nodes carefully before activation. This catalog entry is intended to help you inspect the workflow structure, understand required services, and find related templates faster.

Node names, credentials, schedules, webhook paths, and external service limits may need adjustment for your workspace.

Predict airport queue wait times and email alerts with OpenAI and SendGrid

## Quick Overview This workflow accepts traveler flight details via webhook or runs every 5 minutes, predicts airport queue wait times with a custom JavaScript model, generates an alert message using OpenAI, emails the traveler via SendGrid, and logs the prediction to Google Sheets. ## How it works 1. Receives a POST request to a webhook with traveler/flight details or runs on a 5-minute schedule. 2. Normalizes the incoming data into a consistent context (flight, airport/terminal, traveler contact details, and live queue inputs). 3. Waits briefly to throttle processing, then calculates predicted security, immigration, and boarding wait times plus risk flags and an optimal arrival time. 4. Sends the prediction to OpenAI to generate a short, traveler-friendly alert message. 5. Formats the final alert payload (alert level, email subject/body) and prepares a row for tracking. 6. Sends the alert email through the SendGrid Mail Send API and appends the prediction record to a Google Sheets tab. ## Setup 1. Configure the webhook URL in the system that submits traveler requests (POST to `/airport-queue-check`) or enable the schedule trigger for proactive runs. 2. Add OpenAI credentials and select the chat model used to generate the traveler message. 3. Add Google Sheets OAuth2 credentials and replace `YOUR_SHEET_ID` and the target range (for example, `Predictions!A1:append`) in the Google Sheets request URL. 4. Add your SendGrid API key by replacing `YOUR_SENDGRID_API_KEY` in the Authorization header, and update the sender/recipient fields (including ensuring `travelerEmail` is provided by the trigger payload).

Send transactional SMS with the OVHcloud SMS API

## Quick overview This workflow manually triggers an HTTP request to the OVHcloud SMS API, signing it with your OVH application credentials to send a transactional SMS to a specified phone number. ## How it works 1. Runs when you manually execute the workflow. 2. Sets the OVHcloud API credentials, SMS service name, sender, and target API region. 3. Defines the SMS recipient number and message text to send. 4. Generates the OVHcloud request URL, JSON body, timestamp, and SHA1-based X-Ovh-Signature headers. 5. Sends a POST request to the OVHcloud endpoint `/sms/{serviceName}/jobs` to create an SMS sending job. ## Setup 1. Create OVHcloud API application credentials (Application Key and Application Secret) and a Consumer Key with SMS permissions. 2. Replace the placeholder values for `APPLICATION_KEY`, `APPLICATION_SECRET`, `CONSUMER_KEY`, `SMS_SERVICE_NAME`, `SMS_SENDER`, and `OVH_REGION`. 3. Update the `receiver` (E.164 format) and `message` fields with the SMS details you want to send, and ensure your OVHcloud SMS account has available credits. ## Requirements - OVH account - SMS credits (API account)

Tutor English chat messages using OpenRouter with Postgres memory and log to Supabase

## Quick overview This workflow receives English practice messages via a webhook, uses an OpenRouter chat model with Postgres-backed conversation memory to generate tutoring feedback, logs the exchange to Supabase, and returns the tutor’s reply as a JSON response. ## How it works 1. Receives a POST webhook request containing a `user_id` and `message`. 2. Extracts and standardizes the incoming fields so the workflow has clean `user_id` and `message` values. 3. Sends the message to an AI English tutor powered by OpenRouter, using Postgres chat memory keyed by `user_id` to maintain per-student context. 4. Logs the tutor output to a Supabase `conversations` table along with the user identifier and original message. 5. Returns a JSON response to the caller containing the tutor’s reply. ## Setup 1. Add an OpenRouter API credential and (optionally) choose a different model in the OpenRouter chat model configuration. 2. Add Postgres credentials and ensure the database is reachable from n8n so chat memory can persist sessions by `user_id`. 3. Add Supabase credentials and create a `conversations` table, then confirm the mapped columns (`user_id`, `role`, `message`) match your schema. 4. Copy the webhook URL from n8n and configure your app to POST a JSON body with `user_id` and `message` to that endpoint.
