Quick overview
Quick overview This workflow solves Google reCAPTCHA v2 challenges using CaptchaSonic, supporting webhook-based requests, scheduled monitoring against the reCAPTCHA demo page, and a manual test mode that classifies an image challenge and formats the result for downstream steps. How it works Receives a POST request on a webhook endpoint with the reCAPTCHA v2 site key, website URL, and optional proxy/user-agent settings. Sends the request to CaptchaSonic to generate a reCAPTCHA v2 solution token. Returns the CaptchaSonic solution data back to the caller as a JSON webhook response. Runs on an hourly schedule, sends the Google reCAPTCHA site key and URL to CaptchaSonic to generate a token, and submits the token to the Google reCAPTCHA demo page for validation. Checks the validation response content and outputs a “passed” or “failed” monitoring status with a timestamp. Optionally runs manually with a sample base64 image and question, sends them to CaptchaSonic for reCAPTCHA v2 image classification, and formats the solved result. Setup Install the n8n-nodes-captchasonic community node (requires a self-hosted n8n instance). Create and select a CaptchaSonic API key credential for the CaptchaSonic nodes. If using the webhook path, copy the webhook URL and send a POST body that includes at least websiteKey and websiteURL (and optionally proxy, userAgent, and other fields used by the workflow). If using scheduled monitoring, update the target websiteURL and websiteKey values (currently set to Google’s reCAPTCHA demo) and adjust the schedule interval as needed.
