Custom Captcha Handling in n8n with Hidemium Prompt Script AI

Built with n8n
1

Hi everyone,

I’d like to share a solution we’ve been using to automate flows that involve captcha handling, using n8n in combination with Hidemium – an anti-detect browser that recently added a powerful Prompt Script AI feature.

:exclamation:The Challenge:

When working with automated workflows (like Gmail sign-ups, form submissions, or login bots), CAPTCHAs often interrupt the process and are hard to bypass with standard tools like Puppeteer or Playwright.

:wrench: Our Stack:

  • n8n for orchestration
  • Hidemium for isolated browser environments & fingerprint evasion
  • Prompt Script AI to write automation logic using natural language

:bulb: How it Works:

With Hidemium, we simply write prompts like:

“Go to Gmail signup, wait for captcha, take a screenshot, send to CapMonster API, input the solved code, and continue.”

This drastically simplifies scripting. No more writing selectors or JS injection manually.

:arrows_counterclockwise: Our n8n Flow:

  1. Trigger Node: Starts the automation
  2. Webhook or Execute Command: Calls Hidemium with a prompt
  3. HTTP Node: Sends captcha to solving service (e.g., CapMonster, 2Captcha)
  4. Wait + Merge: Retrieves and injects the result back via browser
  5. Success Webhook / DB Log: Finalizes the process

:rocket: Results:

  • ~95% success rate on Gmail, TikTok, and similar platforms
  • Stable profile management with Hidemium’s browser engine
  • No-code/low-code automation using Prompt Script AI

Let me know if anyone wants a copy of the n8n workflow template we use.
Happy to answer any questions about integrating Hidemium into your n8n setup!

for this we will have to take hidemiums paid plans

Yeah, the advanced scripting features like Prompt Script AI do require a paid plan — but in our case it made sense because we needed stable profile isolation and smoother automation at scale.

If you’re just testing or building simple flows, you might be able to start with the free tier or trial. Worth checking their current limitations before committing long-term.

Absolutely! Happy to hear you’re exploring n8n — it’s way more powerful than it looks at first.

I’ll clean up the workflow template I’ve been using and share a version soon (might need to remove a few API keys and make it more beginner-friendly). It includes the Hidemium prompt call, captcha handling with CapMonster, and a log/reporting step.

Will DM or post a link here shortly — stay tuned!

Absolutely — I’ll DM you the full n8n workflow export file + a sample prompt we used inside Hidemium.

Just a heads up:

  • We’re using CapMonster as the solving service, but you can easily swap in 2Captcha or Anti-Captcha.
  • The flow is modular — so you can plug in your own login/signup logic.
  • Make sure your Hidemium Prompt Script is running with the latest version (some captcha handling functions were added recently).

Let me know if you need help adapting it to your use case — happy to tweak it!
