Solve PopularCaptcha image challenges with CaptchaSonic via webhook

Quick Overview This workflow receives a PopularCaptcha image challenge via webhook or manual test input, sends it to CaptchaSonic for recognition/classification, and returns the solved result as JSON to the caller or as formatted output for testing.

How it works Receives a POST webhook request containing a base64 image, question, websiteURL, and optional extra fields. Sends the challenge details to CaptchaSonic using the PopularCaptcha image recognition/classification operation. Returns CaptchaSonic’s solution data as a JSON webhook response. Optionally, runs a manual test path that loads sample image/question data and submits it to CaptchaSonic. Formats the manual test output by stringifying the solution data and adding a status and timestamp.

Setup Install the n8n-nodes-captchasonic community node in your n8n instance. Create and select a CaptchaSonic credential with your CaptchaSonic API key. If using the webhook path, copy the production webhook URL for /solve-popularcaptcha and configure your client to POST image, question, websiteURL, and optionally extraFields in the request body. If needed, replace the hardcoded sample data in the manual test input to match your PopularCaptcha payload format.
