CAPTCHA Solving API Guide: reCAPTCHA, Turnstile and Play Integrity
Modern applications increasingly use CAPTCHA systems and device attestation to protect sign-up, login and payment flows. For legitimate app testing, QA automation and integration monitoring, teams need a CAPTCHA API that covers Cloudflare Turnstile, reCAPTCHA Mobile and Play Integrity instead of only browser image challenges.
Quick Answer
REGHelp provides API-based CAPTCHA workflows for mobile and web testing. You create a task, poll or receive a webhook, and use the returned token in your test environment.
| Challenge type | REGHelp endpoint family | Best for | Typical latency |
|---|---|---|---|
| Cloudflare Turnstile | /turnstile/getToken | Web sign-up and anti-abuse checks | 1-3s |
| reCAPTCHA Mobile | reCAPTCHA Mobile endpoints | Native Android/iOS app testing | 3-8s |
| Play Integrity | Integrity endpoints | Android device/app attestation testing | 2-5s |
Start with the REGHelp API documentation if you already have an API key, or compare buying criteria in the CAPTCHA API services comparison.
Supported CAPTCHA Types
Cloudflare Turnstile Turnstile is Cloudflare's privacy-preserving alternative to reCAPTCHA. It generates cryptographic tokens that prove a visitor is human without requiring interactive challenges. REGHelp solves Turnstile challenges and returns valid tokens.
reCAPTCHA Mobile (Enterprise) Google's reCAPTCHA for mobile apps uses device attestation and behavioral analysis. Our solver handles both Android and iOS variants of reCAPTCHA Enterprise SDK (v18.7.x).
Play Integrity Google's device attestation API that verifies app and device integrity. REGHelp generates valid Play Integrity tokens for testing environments.
How CAPTCHA Solving Works
- Submit task — send CAPTCHA parameters (site key, URL, type) via GET request
- Processing — our workers solve the challenge using real devices
- Poll status — check task status until
done - Get result — receive a valid token to use in your application
Create Turnstile task:
GET https://api.reghelp.net/turnstile/getToken?apiKey=YOUR_KEY&url=https%3A%2F%2Fexample.com&siteKey=0x4AAAA...
Response:
{
"id": "664462c0f45c5b1b760b7c3e",
"service": "example.com",
"product": "turnstile",
"price": 0.50,
"balance": 99.50,
"status": "success"
}
Poll for result:
GET https://api.reghelp.net/turnstile/getStatus?apiKey=YOUR_KEY&id=664462c0f45c5b1b760b7c3e
{
"id": "664462c0f45c5b1b760b7c3e",
"status": "done",
"token": "0.valid_turnstile_token...",
"message": "OK"
}
Performance Metrics
| CAPTCHA Type | Avg. Solve Time | Success Rate |
|---|---|---|
| Turnstile | 1-3 seconds | 98%+ |
| reCAPTCHA Mobile | 3-8 seconds | 95%+ |
| Play Integrity | 2-5 seconds | 97%+ |
CAPTCHA API vs Browser Automation
| Requirement | CAPTCHA API | Browser-only automation |
|---|---|---|
| Native mobile app coverage | Strong | Weak |
| Play Integrity testing | Supported | Not practical |
| Repeatable CI jobs | Easier with API responses | More fragile |
| Operational overhead | API key, polling and webhooks | Browser fleet, proxies and maintenance |
| Best fit | QA, monitoring, app automation | UI-only browser tests |
Use Cases
- QA Testing — verify your app works correctly with CAPTCHA protection
- Load Testing — simulate real traffic including CAPTCHA validation
- Monitoring — automated uptime checks on CAPTCHA-protected pages
- Development — test CAPTCHA integration during development
Integration Tips
- Always check the task status before using the token
- Tokens have limited validity (typically 2-5 minutes)
- Implement async polling or use webhooks for best performance
- Keep your API key secure and rotate it periodically
- Use push tokens or email accounts when CAPTCHA is only one step in a larger verification flow
