Didit Liveness, passive liveness capture with sub-2-second on-device verdict.

iBeta-certified

Passive. Flash.
Active. All certified.

Catch 3D masks, deepfakes, replay attacks, and printed photos. iBeta-certified, sub-2-second verdict, $0.10 per check, 500 free every month.

How it works

From sign-up to verified user in four steps.

  1. Step 01

    Create the workflow

    Pick the checks you want, ID, liveness, face match, sanctions, address, age, phone, email, custom questions. Drag them into a flow in the dashboard, or post the same flow to our API. Branch on conditions, run A/B tests, no code required.

  2. Step 02

    Integrate

    Embed natively with our Web, iOS, Android, React Native, or Flutter SDK. Redirect to a hosted page. Or just send your user a link, by email, SMS, WhatsApp, anywhere. Pick what fits your stack.

  3. Step 03

    User goes through the flow

    Didit hosts the camera, the lighting cues, the mobile hand-off, and accessibility. While the user is in the flow, we score 200+ fraud signals in real time and verify every field against authoritative data sources. Result in under two seconds.

  4. Step 04

    You receive the results

    Real-time signed webhooks keep your database in sync the moment a user is approved, declined, or sent to review. Poll the API on demand. Or open the console to inspect every session, every signal, and manage cases your way.

Built for developers · Built against fraud · Open by design

Six capabilities. One feature flag. LIVENESS.

Every capability below is a toggle on the same module. No upsell tiers, no separate SKUs, no add-on calls. Switch them on per workflow in the console, or pass them inline on the standalone endpoint.
01 · Methods

Passive, 3D Flash, 3D Action. Pick per risk.

Three methods on one module. Passive (one frame, zero user action) for low-friction sign-up. 3D Flash (a short light sequence captures depth from reflection) for higher-value passive flows. 3D Action & Flash (motion + flash) for regulator-sensitive markets and large-value onboarding.
02 · Certified anti-spoof

Tested against the full presentation-attack catalogue.

Independently tested and iBeta-certified, the standard NIST and the Open Identity Exchange cite. Blocks printed photos, screen replays, paper masks, silicone masks, latex masks, morph attacks, and AI-generated deepfakes. Re-tested annually as the attack catalogue grows.
03 · Sub-2-second verdict

End-to-end inference in under two seconds.

Edge-served inference. No model download, no on-device acceleration assumption, no degraded experience on entry-level Android. Passive completes in under a second on most devices. Flash adds ~600ms. Active 3D adds ~1.5s, still sub-2 end to end.
04 · Warnings

Tunable risk policy per workflow.

Seven configurable warnings, low score, possible duplicate, duplicate face, multiple faces, low face quality, low light, high light, each mapped to decline, review, or approve per application. Three auto-decline triggers (no face, attack detected, blocklisted face) stay enforced no matter what.
05 · Age estimation

One capture, two signals.

Toggle Age Estimation on a liveness workflow and the same selfie returns a liveness verdict plus an estimated age band. Built for UK Online Safety Act and EU age-gating, real-human-AND-old-enough without putting a user through ID upload. $0.10 per check.
06 · Biometric authentication

The same engine you use at sign-up. Now at every login.

Liveness is the foundation for Biometric Authentication, reuse the same anti-spoof model to verify returning users at every sensitive action: high-value transfer, password reset, large withdrawal. $0.10 per auth, drop-in for SMS 2FA, no carrier bill, no SIM-swap exposure.
Integrate

Two endpoints. Same JSON. Same price.

Create a session when you want our hosted UI to handle capture (required for active methods), or call the standalone passive endpoint when you already have the selfie. Both return the same liveness report.
POST /v3/session/Hosted UI
$ curl -X POST https://verification.didit.me/v3/session/ \

Agent-ready integration

Ship Liveness in one prompt.

Paste the block below into Claude Code, Cursor, Codex, Devin, Aider, or Replit Agent. Fill in the my_stack placeholder with your framework, language, and use case. The agent provisions Didit, builds the workflow with Liveness enabled, wires the webhook, and ships.

# Didit Liveness — integrate in 5 minutes

You are integrating Didit's Liveness (presentation-attack detection) module
into <my_stack>. Follow these steps exactly. Every URL, header, and enum
value below is canonical — do not paraphrase or "improve" them.

## 1. Provision an account
- Sign up: https://business.didit.me (no credit card required).
- Or provision programmatically: POST https://apx.didit.me/auth/v2/programmatic/register/
  (returns an API key bound to the workspace + application).

## 2. Two integration paths — pick one

### Path A — Workflow Builder (hosted UI)
Best when you want Didit to handle camera, motion prompts, low-light
fallback, mobile handoff, and accessibility for you.

1. Create a workflow that contains the LIVENESS feature:
   POST https://verification.didit.me/v3/workflows/
   Authorization header:  x-api-key: <your-api-key>
   Body: workflow_label, features array with the single entry
         { feature: "LIVENESS" }   (UPPERCASE — strict enum)
   Optional config: liveness_method ("PASSIVE" | "FLASHING" | "ACTIVE_3D")
   and per-warning threshold overrides.

2. Create a verification session for an end user:
   POST https://verification.didit.me/v3/session/
   Body: workflow_id (from step 1), vendor_data (your own user id).
   Response: session_url — redirect the user to it.

3. Listen for webhook callbacks (see "Webhooks" below).

### Path B — Standalone server-to-server API
Best when you already have a selfie image (mobile SDK capture, native
onboarding app, reseller pipeline). Standalone is single-frame
PASSIVE only — for ACTIVE_3D or FLASHING you must use Path A.

POST https://verification.didit.me/v3/passive-liveness/
Content-Type: multipart/form-data
Body fields:
  - image        (required, file — single selfie)
  - vendor_data  (optional string, your user id)

Response: JSON report with liveness score, method, and warnings array.

## 3. Webhooks (Path A only — Path B returns synchronously)
- Register a webhook destination once via
  POST https://verification.didit.me/v3/webhook/destinations/
  Body: url, subscribed_events: ["session.verified", "session.review_started",
                                  "session.declined"]
- Response includes secret_shared_key — store it.
- Every webhook delivery carries an X-Signature-V2 header you MUST verify
  before trusting the payload.  HMAC-SHA256 verification MUST run against the raw body bytes (the raw payload as Didit sent it) BEFORE any JSON parsing — re-serialising the parsed body changes whitespace and key order, which invalidates the signature.Algorithm:
    1. sortKeys(payload) recursively
    2. shortenFloats (truncate trailing zeros after the decimal point)
    3. JSON.stringify the result
    4. HMAC-SHA256 with the secret_shared_key
    5. Hex-encode, compare to the X-Signature-V2 header.

## 4. Reading the report (both paths return the same shape)
The liveness object includes:
- status: "Approved" | "Declined" | "In Review" | "Not Finished"
- method: "PASSIVE" | "FLASHING" | "ACTIVE_3D"
- score: number 0-100 (normalized liveness score)
- reference_image: signed URL to the captured selfie (expires in 1 hour)
- video_url: signed URL to the capture video, present only for FLASHING
  and ACTIVE_3D (expires in 1 hour)
- age_estimation: { age, age_range } when enabled in the workflow
- warnings: Array<{ risk, log_type, short_description, long_description }>

Auto-decline risks (always enforced by Didit, not configurable):
- NO_FACE_DETECTED
- LIVENESS_FACE_ATTACK
- FACE_IN_BLOCKLIST

Configurable risks (action per workflow — Decline, Review, or Approve):
- LOW_LIVENESS_SCORE
- POSSIBLE_DUPLICATED_FACE
- DUPLICATED_FACE
- MULTIPLE_FACES_DETECTED
- LOW_FACE_QUALITY
- LOW_FACE_LUMINANCE
- HIGH_FACE_LUMINANCE

## 5. Hard rules — do not change
- Base URL for /v3/* endpoints is verification.didit.me (NOT apx.didit.me).
- Feature enum is UPPERCASE: LIVENESS, ID_VERIFICATION, FACE_MATCH, AML, IP_ANALYSIS.
- Method enum is UPPERCASE: PASSIVE, FLASHING, ACTIVE_3D.
- Auth header is x-api-key (lowercase, hyphenated).
- Webhook signature header is X-Signature-V2 (NOT X-Signature).
- Always verify webhook signatures before trusting payload data.
- Status casing matches exactly: "Approved", "Declined", "In Review",
  "Not Finished" (title-cased, space-separated).

## 6. Pricing reference (public)
- PASSIVE method: $0.10 per check (standalone or bundled)
- FLASHING / ACTIVE_3D methods: $0.15 per check
- Bundled in a full KYC workflow: $0.33 per session (includes Liveness)
- 500 free checks every month, forever, on every account.

## 7. Verify your integration
- Sandbox starts on signup at https://business.didit.me — no separate flag.
- Test images: deterministic synthetic faces returned in sandbox (Approved
  by default; trigger Declined by sending the canonical "spoof" test image).
- Switch to live: flip the application's environment toggle in console.

FAQ

Common questions

What is Didit?

Didit is infrastructure for identity and fraud, the platform we wished existed when we were building products ourselves: open, flexible, and developer-friendly, so it works as a real part of your stack instead of a black box you integrate around.

One API covers verifying people (KYC, know your customer), verifying businesses (KYB, know your business), screening crypto wallets (KYT, know your transaction), and monitoring transactions in real time, on a stack built to be:

  • Fast, sub-2-second p99 on every session
  • Reliable, in production with 1,500+ companies across 220+ countries
  • Secure, SOC 2 Type 1, ISO 27001, GDPR-native, and formally attested by Spain's financial regulator as safer than verifying someone in person

The footprint underneath: 14,000+ document types in 48+ languages, 1,000+ data sources, and 200+ fraud signals on every session. The Didit infrastructure dynamically learns from every session and gets better every day.

What inputs does Liveness accept?
A single selfie. Path A, Workflow Builder: the hosted UI captures the selfie inside the user's session, passive needs no user action, 3D Flash plays a short colour sequence, 3D Action prompts a head movement. Comes for free with the session, no extra capture work on your side. Path B, Standalone API: you pass the image yourself as user_image on a multipart POST /v3/passive-liveness/. Accepted formats: JPG, JPEG, PNG, up to 5 MB. Both paths return the same liveness JSON shape.
What is the response shape?
A root-level liveness object with status (Approved, Declined, In Review, or Not Finished), a 0–100 score, the method used (PASSIVE, FLASHING, or ACTIVE_3D), an age_estimation float (optional, when bundled), a signed reference_image URL, a signed video_url for active methods, a matches array surfacing any face-search hits (each with session_id, similarity_percentage, is_blocklisted), and a warnings array. Each warning carries risk, log_type (information, warning, or error), short_description, and long_description. Same shape whether you called the Workflow Builder or the standalone API. Full reference at docs.didit.me/core-technology/liveness/report-liveness.
How fast is the verification for my end user?

The full flow normally takes under 30 seconds end-to-end, pick up the ID, snap the document, snap the selfie, done. That is the fastest in the market. Legacy KYC providers usually take more than 90 seconds for the same flow.

On the back end, Didit returns the result in under two seconds at p99, measured from the moment the user finishes the selfie to the moment your webhook fires. Mobile capture is tuned for slow phones and slow networks: progressive image compression, lazy software development kit load, and a one-tap hand-off from desktop to phone via QR code if the user starts on web.

How does Didit defeat deepfakes, masks, and replay attacks?

Three methods, one module, iBeta Level 1 Presentation Attack Detection (PAD) certified across the full attack catalogue:

  • Passive, one frame, zero user action. Catches printed photos, screen replays, and basic morph attacks. Best for low-friction sign-up.
  • 3D Flash (`FLASHING`), plays a short colour sequence on the phone screen and measures the reflection on the face. Defeats 2D screen replays and high-fidelity printed masks.
  • 3D Action (`ACTIVE_3D`), combines a head-movement prompt with the flash sequence. Defeats 3D silicone masks and AI-generated deepfake video. Best for high-value onboarding and regulator-sensitive markets.

Seven configurable warnings (low score, low light, high light, possible duplicate, duplicate face, multiple faces, low face quality) map to decline / review / approve per application. Three auto-decline triggers (no face, attack detected, blocklisted face) are always enforced.

What happens if a user fails, abandons, or expires?

Every session lands on one of seven clear statuses, so your code always knows what to do:

  • Approved, every check passed. Move the user forward.
  • Declined, one or more checks failed. You can allow the user to resubmit the specific failed step (for example, re-take the selfie) without re-running the whole flow.
  • In Review, flagged for compliance review. Open the case in the console, see every signal, decide approve or decline.
  • In Progress, user is mid-flow.
  • Not Started, link sent, user has not opened it yet. Send a reminder if it sits too long.
  • Abandoned, user opened the link but did not finish in time. Re-engage or expire.
  • Expired, the session link aged out. Create a new session.

A signed webhook fires on every status change, so your database always stays in sync. Abandoned and declined sessions are free.

Where does my customer data live and how is it protected?

Production data is processed and stored in the European Union by default, on Amazon Web Services. Enterprise contracts can request alternative regions for jurisdictions whose regulators require it.

Encryption everywhere. AES-256 at rest across every database, object store, and backup. Transport Layer Security 1.3 in transit on every API call, webhook, and Business Console session. Biometric data is encrypted under a separate Customer Master Key.

Retention is yours to control. Default retention is indefinite (unlimited) unless you configure shorter, between 30 days and 10 years per application, and you can delete any individual session at any time from the dashboard or the API.

Certifications: SOC 2 Type 1 (Type 2 audit in progress), ISO/IEC 27001:2022, iBeta Level 1 PAD, and a public attestation from Spain''s Tesoro / SEPBLAC / CNMV that Didit''s remote identity verification is safer than verifying someone in person. Full report at /security-compliance.

Is Didit compliant for my industry?

Didit ships compliant by default for the regulators that matter to identity infrastructure:

  • GDPR + UK GDPR, controller / processor split, full Data Processing Agreement published, lead supervisory authority named (Spain''s AEPD).
  • AMLD6 + EU AML Single Rulebook, 1,300+ sanctions, politically exposed person, and adverse-media lists screened in real time.
  • eIDAS 2.0, EU Digital Identity Wallet aligned; reusable-identity ready.
  • MiCA (Markets in Crypto-Assets), ready for crypto on-ramps, exchanges, and custodians.
  • DORA, Digital Operational Resilience Act, EU financial-services operational resilience.
  • BIPA, CUBI, Washington HB 1493, CCPA / CPRA, US biometric privacy (Illinois, Texas, Washington) and California consumer privacy.
  • UK Online Safety Act, age-gating and child-safety obligations.
  • FATF Travel Rule, originator and beneficiary data on crypto transfers, IVMS-101 interoperable.

Detailed memo, every certificate, every regulator letter: /security-compliance.

How fast can I integrate and start verifying users?
  • 60 seconds to a sandbox account at business.didit.me, no credit card.
  • 5 minutes to a working verification through Claude Code, Cursor, or any coding agent via our Model Context Protocol (MCP) server.
  • A weekend to a production-ready integration with signed-webhook verification, retries, and a remediation flow when a user is declined.

Three integration paths, pick whichever fits your stack:

  • Embed natively with our Web, iOS, Android, React Native, or Flutter SDK.
  • Redirect the user to the hosted verification page, zero SDK.
  • Send a link by email, SMS, WhatsApp, or any channel, zero front-end work.

Same dashboard, same billing, same pay-per-success price for all three. Step-by-step guide at docs.didit.me/integration/integration-prompt.
