Что маркетплейс должен
Закон ЕС о цифровых услугах и новый пакет мер по борьбе с отмыванием денег делают верификацию продавцов юридическим обязательством. Didit предлагает это как единый рабочий процесс: проверка реестра, извлечение данных о владельце, KYC для каждого владельца и OCR документов, всё это привязано к одной записи продавца. $2.00 за продавца, $0.33 за владельца. 500 бесплатных верификаций каждый месяц.
Выберите нужные проверки: ID, Liveness, Face Match, санкции, адрес, возраст, телефон, email, кастомные вопросы. Перетащите их в рабочий процесс на дашборде или отправьте тот же процесс в наш API. Настраивайте ветвления по условиям, проводите A/B-тесты, код не нужен.
Встраивайте нативно с помощью наших SDK для Web, iOS, Android, React Native или Flutter. Перенаправляйте на размещённую страницу. Или просто отправьте пользователю ссылку, по email, SMS, WhatsApp, куда угодно. Выберите то, что подходит вашему стеку.
Didit обеспечивает работу камеры, подсказки по освещению, мобильную передачу данных и доступность. Пока пользователь проходит проверку, мы в реальном времени оцениваем более 200 признаков мошенничества и верифицируем каждое поле по авторитетным источникам данных. Результат, менее чем за две секунды.
Подписанные вебхуки в реальном времени синхронизируют вашу базу данных в момент одобрения, отклонения или отправки пользователя на проверку. Опрашивайте API по запросу. Или откройте консоль, чтобы просмотреть каждую сессию, каждый сигнал и управлять кейсами по-своему.

# Decision payload (excerpted):
{ "session_kind": "business", "status": "APPROVED",
"decision": { "company": { "legal_name": "Maker Goods Ltd.", "registry_status": "ACTIVE" },
"key_people": [ ... kyc_session_url per owner ... ]
} }статус APPROVED · IN_REVIEW · DECLINED · AWAITING_USERYou are integrating Didit into a marketplace that lists third-party sellers (Etsy, Shopify, Faire, Amazon Handmade, OnBuy archetype). EU Digital Services Act Article 30 and the new EU Anti-Money Laundering (AML) package require you to verify the seller (KYB) before any listing goes live, and to keep that verification fresh while they sell.
Four obligations on every seller:
1. Pull the company's registry record (legal name, registration number, status, incorporation date) from the authoritative government source.
2. Extract every Ultimate Beneficial Owner (UBO) — anyone owning 25% or more — and run a closed-loop KYC on each one.
3. Screen the company AND every UBO against sanctions, Politically Exposed Persons (PEP), and adverse-media lists.
4. Collect the corporate evidence (certificate of incorporation, tax registration, proof of business address) and watch the seller continuously for status changes, UBO turnover, AML hits, and document expiry.
Pricing (verified live):
- KYB session (registry + company AML + documents + key-people flow): $2.00 per seller, pay-per-call
- Linked KYC per UBO: $0.33 per UBO (ID + Passive Liveness + Face Match + IP + AML)
- Ongoing AML monitoring: $0.07 per user per year
- First 500 KYC verifications free every month, forever
PRE-REQUISITES
- Production API key from https://business.didit.me (sandbox key in 60s, no card).
- Webhook endpoint with HMAC SHA-256 verification using the X-Signature-V2 header and your webhook secret.
- A workflow_id for KYB from the Workflow Builder. The workflow's type (KYC or KYB) drives the session shape — no explicit business flag is needed on the request.
- A workflow_id for KYC bundled with ID + Passive Liveness + Face Match + IP + AML, used for the linked UBO sessions.
STEP 1 — Create the KYB session
POST https://verification.didit.me/v3/session/
Headers:
x-api-key: <your api key>
Content-Type: application/json
Body:
{
"workflow_id": "<your KYB workflow id>",
"vendor_data": "<your seller id, max 256 chars>",
"callback_url": "https://<your-app>/sellers/kyb/callback",
"expected_country": "GB",
"metadata": {
"seller_id": "<your internal seller id>",
"marketplace_segment": "handmade"
}
}
Response: 201 Created with the hosted session URL. Email it to the seller or embed it in your onboarding UI. Behind the scenes, Didit runs:
- kyb_registry — live registry lookup against the country's authoritative source
- kyb_company_aml — sanctions / PEP / adverse media on the company
- kyb_documents — document collection + Optical Character Recognition (OCR) (incorporation, TIN, proof of address)
- kyb_key_people — UBO + director extraction with linked-KYC sessions
STEP 2 — Read the signed webhook on KYB completion
Didit POSTs to your callback. KYB SESSION statuses are UPPER_SNAKE_CASE:
Body (excerpted):
{
"session_id": "<uuid>",
"session_kind": "business",
"vendor_data": "<your seller id>",
"status": "APPROVED",
"decision": {
"company": {
"legal_name": "Maker Goods Ltd.",
"registration_number": "1029847",
"country_code": "GB",
"registry_status": "ACTIVE"
},
"features": [
{ "node_id": "kyb_registry", "status": "APPROVED" },
{ "node_id": "kyb_company_aml", "status": "APPROVED", "total_hits": 0 },
{ "node_id": "kyb_documents", "status": "APPROVED" },
{ "node_id": "kyb_key_people", "status": "APPROVED",
"key_people": [
{ "uuid": "<uuid>", "name": "Sara Ortega", "role": "director", "is_ubo": true, "ownership_percentage": 60, "kyc_status": "Approved", "kyc_session_url": "https://verify.didit.me/..." },
{ "uuid": "<uuid>", "name": "Niels Janssen", "role": "shareholder", "is_ubo": true, "ownership_percentage": 30, "kyc_status": "Approved", "kyc_session_url": "https://verify.didit.me/..." }
]
}
]
}
}
SESSION status enum (KYB · UPPER_SNAKE_CASE):
NOT_STARTED | IN_PROGRESS | AWAITING_USER | APPROVED | DECLINED | IN_REVIEW | RESUBMITTED | ABANDONED | EXPIRED
FEATURE status enum (inside decision.features[].status · UPPER_SNAKE_CASE):
NOT_FINISHED | APPROVED | DECLINED | IN_REVIEW | RESUB_REQUESTED | AWAITING_USER
Note: kyc_status on key_people IS Title Case ("Approved" / "Declined" / "Pending") — those are KYC sessions linked from inside the KYB feature, not KYB features themselves.
Verify the X-Signature-V2 header BEFORE reading the body — HMAC SHA-256 of the raw bytes with your webhook secret.
STEP 3 — Linked KYC on each UBO is automatic
When the seller completes the hosted KYB flow and submits the UBO list, Didit spawns a child KYC session per UBO using the KYC workflow you configured on the KYB workflow. Each child session has its own session_id and its own hosted URL on the kyc_session_url field inside the key-people block.
You don't need to call POST /v3/session/ again for the UBOs — they're stitched to the parent KYB session automatically. You DO need to drive each UBO through their hosted KYC URL (email it, SMS it, embed it in your seller dashboard).
Per-UBO KYC session status is Title Case With Spaces (KYC convention):
Approved | Declined | In Review | Resubmitted | Expired | Not Finished | Kyc Expired | Abandoned
Linked-KYC pricing: $0.33 per UBO.
STEP 4 — Retrieve the decision
GET https://verification.didit.me/v3/session/{sessionId}/decision/
Headers:
x-api-key: <your api key>
Returns the full KYB decision payload — company block, AML hits, document OCR, every UBO with their kyc_status and kyc_session_url. Use this for audit-pack export and for re-rendering the seller status in your admin UI.
STEP 5 — Decide
Branch logic:
APPROVED → activate the seller, allow listings.
IN_REVIEW → keep listings off, wait for analyst webhook update.
DECLINED → refuse onboarding, log the decision_reason_code.
AWAITING_USER → nudge the seller to complete the pending step (typically UBO list submission).
Pre-DSA Article 30: store the trader information (legal name, registration number, address, contact) in your trader-information record alongside the decision payload.
STEP 6 — Ongoing monitoring is automatic when enabled
Enable Ongoing AML on the seller and on each UBO ($0.07/user/year). The session status updates automatically as new sanctions hits land, dissolutions are filed in the registry, or document expirations approach. Your webhook fires on every state change.
No separate endpoint to call — the same workflow drives it.
WEBHOOK EVENT NAMES
- status.updated — session status changed (filter on data.session_kind === "business" for KYB).
- data.updated — session data changed (registry refresh, key-people submission, document upload, ongoing AML hit).
- business.status.updated — the linked Business entity changed.
- business.data.updated — Business entity data changed.
Verify X-Signature-V2 on every payload. The webhook secret is per-environment — sandbox key is separate from production.
CONSTRAINTS
- KYB session statuses use UPPER_SNAKE_CASE (APPROVED, IN_REVIEW, DECLINED). KYC session statuses use Title Case (Approved, In Review, Declined). They live in different APIs — don't mix them in the same code path.
- Default record retention is 5 years post-relationship per the EU AML package; some jurisdictions go higher.
- You cannot replace the registry lookup with a self-attested form — DSA Article 30 requires the data to come from an authoritative source.

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:
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.
Know Your Business (KYB) is the process of verifying that a company is real, that it's still trading, and that you know who actually owns and controls it. For a marketplace it has three pieces:
It's the business-side equivalent of KYC (Know Your Customer). On a marketplace that lists third-party sellers, you owe it before any listing goes live. Didit ships the whole recipe as one workflow for $2.00 per seller + $0.33 per owner.
Any marketplace that lets a third party offer goods or services to consumers and takes payment for it. That covers:
In the European Union the Digital Services Act (the EU's online-platform rulebook) makes seller verification a hard requirement, with material fines for non-compliance. The UK, US, and most of Latin America have parallel obligations under their own consumer-protection and anti-money-laundering rules.
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.
Three things, in order of how often they bite a marketplace:
The historical record on this is unforgiving. Almost every major marketplace has been fined for letting unverified sellers operate. KYB is the standard control.
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.
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.
Didit ships compliant by default for the regulators that matter to identity infrastructure:
Detailed memo, every certificate, every regulator letter: /security-compliance.
Three integration paths, pick whichever fits your stack:
Same dashboard, same billing, same pay-per-success price for all three. Step-by-step guide at docs.didit.me/integration/integration-prompt.
Two enum sets, one per session kind:
The casing difference is deliberate, UPPER_SNAKE for the KYB session, Title Case for the KYC session. They sit in different APIs; don't mix them in the same code branch.
For a webhook handler, switch on the parent KYB status. AWAITING_USER is the most common interim state, it usually means the seller still has to submit the owner list or re-upload a document. The state transitions to IN_REVIEW or APPROVED automatically once they do.
Verification at signup is necessary but not sufficient, sellers change over time, owners move in and out, and sanctions lists update daily. Didit's ongoing monitoring catches all of it:
Everything flows through the same status.updated webhook you already wired for onboarding. No new endpoint, no extra integration.
Most KYB providers price between $8 and $50 per check, often with floor commits in the thousands of dollars per month and per-country surcharges. The Middesk / Persona KYB / Onfido Business archetype.
Didit's published price is $2.00 per KYB session + $0.33 per linked KYC. No floor, no commit, no per-country surcharge, no hidden registry fees. Pay only for what runs.
That's 3–5× cheaper than the incumbent stack on the same regulatory output. The economics matter because seller verification is a per-listing cost, at scale the difference between $2 and $25 is the difference between accepting a seller and refusing them. Full pricing at /pricing.
