iOS CAPTCHA SDK

Add an iOS CAPTCHA to protect iPhone and iPad apps from automated spam, fake sign-ups and account takeover attempts, without image puzzles. There is no pre-built SDK yet, so you embed the widget yourself. It runs in the background, and allow and block lists plus geoblocking let you set how strict it is. EU-hosted and GDPR-compliant.

Quickstart

How the integration works

1. Create a CAPTCHA

Create a user account or log in with an existing one. Then create a new CAPTCHA or pick an existing one. If you want to try TrustCaptcha first, every plan comes with a 14-day free trial.

The CAPTCHA overview page shows your site key and license key, and you create your API key there. Add your website’s domains to the authorized domains in the CAPTCHA security rules so they can use your CAPTCHA.

2. Integrate the CAPTCHA widget into your frontend

There is no pre-built integration for iOS yet, but you can still use TrustCaptcha in iOS apps. Your developers can integrate the CAPTCHA widget into any iOS app themselves using our documentation.

If you would like a pre-built iOS CAPTCHA SDK, contact our support team. We will check whether we can move its development forward.

After the integration, the CAPTCHA widget will be displayed in your iOS app:

Other frontend technology instead of iOS?
If you build with something other than iOS, or run several websites and apps, pick a different framework or platform here. If we have no pre-built integration for your frontend technology yet, your developers can integrate the CAPTCHA themselves using our documentation or ask our support team for a pre-built integration.

3. Validate the CAPTCHA result in your backend

When the CAPTCHA is complete, send the verification token to your backend. There, fetch the verification result from our servers and check it. How you proceed depends on the bot risk. You can find details on backend integration and result validation in our documentation.

Pre-built backend integrations
Our pre-built integrations add the CAPTCHA validation to your backend service. If there is none for your backend technology yet, your developers can integrate the validation themselves using our documentation or ask our support team for a pre-built integration.
