Liveness SDK: Tutorial screen changes

• Updated the tutorial images and text contents

• New fields for locale customization

CDN:

NPM:

Feature

Date: Jul 21th, 2026

• VidaSDK.preload() - Introduced a new method which preload() prefetches SDK assets in the background so they are already cached when the SDK starts the flow. This reduces perceived load time for the end user.

• userInfo.Id is made an optional parameter for init() method now for Liveness+Id Fraud shield combined offering.

• Added an exit confirmation pop-up if user tries to manually close the modal during the process, if there is a retry or flow completion possibility.

Feature

Date: Apr 28th, 2026

• Integration with the ID Fraud Shield SDK, enabling risk-based actions across both Liveness and KYC flows.

• Enhanced callback responses with more details to improve visibility during the liveness process.

• onComplete(data) - this callback fires once when liveness passes; returns the successful liveness result. Treat as the success signal. onError(data) - this callback fires only at terminal, flow-ending states (max-retry exhausted, session expired, detection timeout, camera/startup errors, manual close). Retry-able liveness failures do not trigger it — except with skipSelfieReviewScreen, where each failure is terminal. onLivenessApiResponse(data) — this callback fires on every liveness API response whether the attempt passed or failed on threshold/image quality. Can be used for per-attempt observability, not a terminal signal.
