We have put a lot of effort into making integration as simple and straightforward as possible by providing the following integration types.

Verification Links

No code

Create verification links that you can easily share with your applicants, code-free.

Sumsub SDKs

Recommended

Build in PHP, Java, Python, Node.js, Ruby, .NET, iOS, Android, React Native, and Flutter.

Sumsub API

Most code

Send and receive applicant data through simple RESTful APIs.

These integration types can be combined to give you greater precision and flexibility for your specific business scenarios.

No matter which type you choose, you will always be able to:

• Conduct effective identity and address verification for your applicants, manage results, and stay in full control of the entire process
• Perform document-free verification—a convenient method where applicants only need to provide their ID number and prove their identity using biometric data and other verified information from reliable government sources.
• Monitor inbound and outbound transactions using our Transaction Monitoring solution, including Travel Rule and Gambling compliance.
• Carry out Business Verification—delegate AML watchlist and registry screening, ultimate beneficial owner (UBO) verification, and corporate structure checks to Sumsub

Enhance fraud protection with SDK Integration

If boosting the security of your verification flows is a priority, the SDK is the best integration choice, providing multiple comprehensive tools out of the box. All new fraud detection features, built on Sumsub's collective client experience, are automatically integrated into SDK capabilities—with no additional action required on your end.

The paragraphs below outline the SDK's key features, making it a more convenient and secure integration option.

Document processing

The SDK fully controls how documents are captured during verification, handling both forgery detection and quality assurance. This enables you to detect fraud in real time and manage unsatisfactory image uploads.

Liveness & Face Match support

Only the SDK supports our Liveness feature, which creates a 3D face map to confirm that a real person is present. Specifically, Liveness can detect:

• Signs of deepfake and other types of AI generation
• Paper masks
• Screen replays
• Dolls or mannequins
• Asleep users
• Forced verification

Fraud prevention capabilities

When conducting verification within the SDK, the process is enhanced by our in-house fraud prevention mechanisms:

• Link sharing detection — the SDK flags when a verification link is used by someone other than the intended user, helping catch money mules and verification scams.
• Behavior analysis — the SDK helps detect unusual patterns, such as a session completed much faster than average, or one that stops and restarts from a new, distant location.
• Scam protection — the SDK notifies the user where they continue verification after following a link or QR code.
• Device intelligence — the SDK provides full access to the Device Intelligence product to detect multiple devices in one session, rooted or jailbroken devices, GPS spoofing, and risky IPs (VPN, Tor, proxy). The SDK shares this data with Sumsub Fraud Network Detection, which helps identify suspicious connections across applicants within the platform.
