1.1 Workflow description

Title: Solve captchas via webhook with CapSolver
Workflow name: Solve captchas via webhook with CapSolver

Solve Any CAPTCHA with CapSolver

How it works

The workflow is triggered by a webhook receiving requests. 2. Input validation is performed on the incoming data. 3. The type of CAPTCHA is determined and routed to the appropriate solver. 4. CAPTCHA solving is attempted using the designated CapSolver node. 5. The response is formatted and sent back via the webhook, or an error response is sent for unsupported CAPTCHA types.

Setup steps

Configure the webhook URL to receive requests.
Set up input validation criteria in the Validate Input node.
Customize the Route by CAPTCHA Type for your specific CAPTCHA types.
Ensure all CapSolver nodes have the correct API credentials.
Deploy the workflow and test with different CAPTCHA inputs.

Customization

You can add or remove specific CapSolver nodes based on the types of CAPTCHA challenges you anticipate.

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.
