We have put a lot of effort into making the integration as simple and straightforward as possible, providing you with 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.

You can use any of these types in combination, making it more precise and customizable, depending on your business scenarios.

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

• Conduct effective identity and address verification of your applicants, manage results, and be at the helm of the entire process.
• Perform document-free verification — a convenient way when all that is required from your applicant is to provide their ID number and prove the identity by submitting biometric data and other established information that can be validated through reliable government sources.
• Monitor inbound and outbound transactions using our Transaction monitoring solution, including Travel Rule and Gambling.
• Carry out Business verification — delegate AML watchlist and registry screening, beneficiary verification, and company 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 from the experience of Sumsub clients, are designed and integrated into SDK capabilities automatically, with no need for you to take any additional action on your side.

The paragraphs below outline the SDK's outstanding characteristics, making it a more convenient and safer integration option.

Document processing

The SDK fully controls how a document is captured during verification, covering both aspects — forgery detection and quality assurance. This lets you detect fraud in real time and handle unsatisfactory image uploads.

Liveness & Face Match support

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

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

Fraud prevention capabilities

When you conduct verification within the SDK, the whole process is greatly enhanced with 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.
