Q: Can I replace the KYC vendor Unit21 currently integrates with?

Yes — and that's the most common reason Unit21 customers add Didit. Unit21 is KYC-agnostic and connects to any KYC provider via webhook or API. If you're currently routing through Persona, Veriff, or Trulioo into Unit21: 1. Add Didit as your KYC provider (one weekend integration, public docs at [docs.didit.me](https://docs.didit.me)). 2. Map Didit's webhook payload to your existing Unit21 user-create call. 3. Cut over traffic. Mirror 10 % first, compare results, flip the rest. Didit ships the same identity signals — document data, biometrics, AML flag, risk score — that Unit21 expects. No changes needed on the Unit21 side.

Q: Is there a native Didit × Unit21 integration?

Not a one-click connector yet — the integration is a webhook mapping your engineering team configures in an afternoon. Both products have open, well-documented APIs, and the data shapes align naturally. If you want help with the integration spec (payload mapping, error handling, retry logic), email `hello@didit.me` and our solutions team will send you the reference implementation. We've done this with dozens of Unit21 customers.

Q: Does Didit satisfy the KYC requirements that regulators expect before transaction monitoring?

Yes. Didit is the only KYC provider an EU government has formally attested as **safer than verifying someone in person** — Spain's Tesoro, Banco de España, and SEPBLAC reviewed and signed off on the architecture. The report is public. Certifications: **SOC 2 Type 1 & Type 2, ISO/IEC 27001:2022, iBeta Level 1 anti-spoofing, GDPR-native**. For US FinCEN/BSA programmes: Didit's document + biometric + AML onboarding check satisfies Customer Identification Program (CIP) requirements and produces audit-ready session records. Aligned with AMLD6, MiCA, eIDAS 2.0.

Q: How does Didit handle step-up verification when Unit21 flags a high-risk transaction?

Unit21 can trigger a Didit step-up verification via webhook or direct API call. When a transaction alert fires, your backend calls `POST /v3/session/` with a `step_up` workflow — typically Passive Liveness + Face Match 1:1 against the original onboarding selfie — and redirects the user to the hosted verification URL. The result comes back in a signed webhook in <2s. Your backend reads the verdict, passes it back to Unit21 as a case annotation, and either clears or escalates the alert. 500 free step-up sessions every month. Paid sessions at the same $0.33 KYC bundle price.

Question 1

Does Didit replace Unit21?

Accepted Answer

No — they operate at different layers of the compliance stack and work best together.

**Unit21** is a Transaction Monitoring and case-management platform: alert triage, SAR (Suspicious Activity Report) filing, AI-assisted investigation. It monitors behaviour after a user is onboarded.

**Didit** is the identity and fraud layer that runs *before* Unit21 sees the user: ID document capture, biometric liveness, face match, AML onboarding screening. Didit verifies who someone is and whether they're high-risk at the point of signup.

The standard pairing: Didit onboards → passes a verified user ID and risk signal to Unit21 → Unit21 monitors transactions going forward.

Question 2

How does Didit feed verified users into Unit21?

Accepted Answer

Via webhook. Every completed Didit session fires a signed webhook (HMAC-SHA256) with the verified identity, document data, AML onboarding result, and risk score. Your backend ingests that event and creates the Unit21 user profile in the same handler — no manual bridge needed.

The `/v3/` API response also returns a structured JSON object with all verification fields (name, DOB, document number, nationality, liveness result, face-match score) that map directly to Unit21's user-create payload.

Integration typically takes an afternoon for an existing Unit21 customer.

Question 3

What does Didit cost as the KYC layer feeding into Unit21?

Accepted Answer

**$0.33 per full KYC check** (ID document + passive liveness + face match + IP analysis, bundled). Compare that to Persona at $1.50 or Veriff at $1.39 — the two providers Unit21 most commonly integrates with today.

Additional modules stack on top at public per-check prices:

- AML onboarding screening: $0.27
- Ongoing AML monitoring: $0.07 / user / year
- Business verification (KYB): $2.00 per business

**500 verifications free every month, forever.** No contract, no minimum. Pay-per-success: failed sessions don't count.

Question 4

Can I use Didit's AML results as risk signals inside Unit21?

Accepted Answer

Yes. Didit's AML onboarding check runs against **1,000+ sanctions, PEP, and adverse-media lists** at the point of signup. The result — hit / no-hit, list name, match confidence — is returned in the session webhook payload and can be forwarded directly to Unit21 as a user-level attribute or risk tag.

Didit also supports **ongoing AML monitoring** ($0.07 / user / year) that re-checks the same person every 24 hours and fires a webhook on any new hit — keeping Unit21's risk profile current without a manual re-verification.

Question 5

Does Didit handle case management or SAR filing?

Accepted Answer

No — that's Unit21's domain. Didit focuses on the identity and fraud layer at onboarding (and during step-up checks): document capture, biometrics, liveness, AML onboarding screening, device & IP analysis.

Once a user is verified and live, any suspicious transaction patterns are Unit21's territory — alert queues, case management, SAR filing, AI-assisted triage. The two tools are designed to be complementary, not overlapping.

Question 6

What's the difference between Didit AML and Unit21 Transaction Monitoring?

Accepted Answer

Two different AML disciplines:

**Didit AML screening** (onboarding-time) — checks a person's identity at the point of signup against sanctions lists, PEP registries, and adverse-media sources. Answers: *is this person on a list?* Runs in <1s as part of the KYC flow.

**Unit21 Transaction Monitoring** (post-onboarding) — watches transaction behaviour over time, applies rule-based alerts, and flags patterns like structuring, layering, and velocity anomalies. Answers: *is this account behaving suspiciously?*

Both layers are required for a complete AML programme. Didit at onboarding + Unit21 in production = the standard stack for regulated fintechs.

Question 7

Can I replace the KYC vendor Unit21 currently integrates with?

Accepted Answer

Yes — and that's the most common reason Unit21 customers add Didit. Unit21 is KYC-agnostic and connects to any KYC provider via webhook or API. If you're currently routing through Persona, Veriff, or Trulioo into Unit21:

1. Add Didit as your KYC provider (one weekend integration, public docs at [docs.didit.me](https://docs.didit.me)).

Didit ships the same identity signals — document data, biometrics, AML flag, risk score — that Unit21 expects. No changes needed on the Unit21 side.
