🚀 How It Works in Your Pipeline

[ Trigger: Webhook / Schedule ]
              │
              ▼
    [ HTTP Request: Target Page ] ──► Extracts sitekey & pageURL
              │
              ▼
  [ 🤖 CapMonster Cloud Node ] ──► Sends task & polls solution asynchronously (< 1s)
              │
              ▼
[ HTTP Request: Submit Form ] ──► Injects gRecaptchaResponse / Turnstile token

The node automatically handles polling, backoff retries, and token delivery directly into JSON output parameters (gRecaptchaResponse, token, etc.).

🛠️ Troubleshooting & Best Practices

• Token Expiration: CAPTCHA tokens typically expire in 120 seconds. Ensure your next HTTP Request executes immediately after the CapMonster node.
• Proxy Matching: For Cloudflare Turnstile or DataDome, use residential proxies with the same IP/subnet that makes the initial page request.
• Custom JSON Payload: If using custom JSON payloads, follow the official CapMonster Task API Reference.
• Zero Balance: Make sure your dashboard balance is positive. Grab free testing credits from your Dashboard.
