一幅电影般的深色抽象租户筛选插画, 四个漂浮的半透明玻璃面板在纯黑色背景上，由一条发光的Didit蓝色线条串联。每个面板都带有一个小的抽象图案（房屋轮廓、交叉钥匙、剪贴板、定位图钉）。

租赁中介的职责

了解申请人。了解他们有租赁能力。在您交出钥匙之前。

纸质筛选速度慢、成本高且易伪造。Didit 用一个托管会话取代了它： 身份 + 活体检测 + 人脸比对 + 地址证明 + AML + 租赁资格检查, 每位申请人 $0.33，地址证明 $0.20。 每月免费提供500次验证，2秒内出结果。

工作原理

从注册到验证用户，仅需四步。

  1. 步骤 01

    创建工作流

    选择您需要的检查项, 身份、活体检测、人脸比对、制裁名单、地址、年龄、电话、电子邮件、自定义问题。在控制面板中将它们拖入工作流，或通过我们的API发布相同的工作流。根据条件进行分支，运行A/B测试，无需代码。

  2. 步骤 02

    集成

    使用我们的Web、iOS、Android、React Native或Flutter SDK进行原生嵌入。重定向到托管页面。或者直接通过电子邮件、短信、WhatsApp等任何方式向您的用户发送链接。选择适合您技术栈的方式。

  3. 步骤 03

    用户完成流程

    Didit 负责托管摄像头、灯光提示、移动设备切换和辅助功能。当用户在流程中时，我们实时评估200多个欺诈信号，并根据权威数据源验证每个字段。结果在两秒内得出。

  4. 步骤 04

    您收到结果

    实时签名的 Webhook 可确保用户批准、拒绝或发送审核的瞬间，您的数据库保持同步。按需轮询 API。或者打开控制台检查每个会话、每个信号，并以您的方式管理案例。

didit-integration-prompt.md
You are integrating Didit into a residential-leasing platform (PropTech / build-to-rent / letting-agent archetype). You owe the landlord (or your platform owes the landlord) an evidence pack on every applicant before the keys come off the hook.

Four obligations on every application:

  1. Verify the applicant's identity — government ID + liveness + face match.
  2. Validate the current address — utility, bank, or registry-issued letter, cross-checked against the ID.
  3. Confirm lease eligibility — Right to Rent (UK) / state-of-residence (US) / residency document (EU) / national tax id (LatAm).
  4. Screen the applicant against sanctions, Politically Exposed Persons (PEP), and adverse-media lists.

Optional: run the same flow against a guarantor and stitch both back to the lease record.

Pricing (verified live):
  - Tenant KYC bundle: $0.33 per applicant (ID + Liveness + Face Match + IP + AML)
  - Proof of Address: $0.20 per check
  - Database Validation (right-to-rent / national id): variable, per-jurisdiction
  - Linked guarantor KYC: $0.33 per guarantor
  - 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 from the Workflow Builder that bundles ID Verification + Passive Liveness + Face Match 1:1 + Proof of Address + AML Screening + the jurisdiction-specific Database Validation node.
  - Optional: a separate KYC workflow_id for the guarantor.

STEP 1 — Create the tenant session

  POST https://verification.didit.me/v3/session/
  Headers:
    x-api-key: <your api key>
    Content-Type: application/json
  Body:
    {
      "workflow_id": "<your tenant-screening workflow id>",
      "vendor_data": "<your applicant id, max 256 chars>",
      "callback_url": "https://<your-app>/applications/kyc/callback",
      "expected_country": "GB",
      "metadata": {
        "application_id": "<your internal id>",
        "property_id": "<unit reference>"
      }
    }

  Response: 201 Created with the hosted session URL. SMS or email the URL to the applicant; they complete everything on their phone in under five minutes.

STEP 2 — Read the signed webhook on KYC completion

  Didit POSTs to your callback. Session statuses are Title Case With Spaces:

  Body (excerpted):
    {
      "session_id": "<uuid>",
      "vendor_data": "<your applicant id>",
      "status": "Approved",
      "id_verification": { "status": "Approved", "document_type": "passport", "country_code": "GB" },
      "liveness": { "status": "Approved" },
      "face": { "status": "Approved", "similarity_score": 0.94 },
      "proof_of_address": { "status": "Approved", "document_type": "utility_bill", "address": { "line1": "10 Long Acre", "city": "London", "postal_code": "WC2E 9LH", "country": "GB" } },
      "aml": { "status": "Approved", "hits": [] },
      "database_validation": { "status": "Approved", "service": "uk_right_to_rent", "result": { "share_code_status": "valid", "expiry_date": "2027-08-12" } }
    }

  Session status enum (exact case):
    Approved | Declined | In Review | Resubmitted | Expired | Not Finished | Kyc Expired | Abandoned

  Verify the X-Signature-V2 header BEFORE reading the body — HMAC SHA-256 of the raw bytes with your webhook secret.

STEP 3 — (Optional) Spawn a guarantor session

  If the workflow declares a guarantor step, the parent session returns a guarantor_session_url inside the decision payload. Email it to the guarantor and they run the same KYC flow on their phone. The result threads back to the parent tenant record automatically.

  Alternatively, fire a second POST /v3/session/ with a separate guarantor workflow_id and stitch the two together by setting metadata.tenant_session_id on the guarantor call.

STEP 4 — Retrieve the full evidence pack

  GET https://verification.didit.me/v3/session/{sessionId}/decision/
  Headers:
    x-api-key: <your api key>

  Returns the full decision payload — ID block, liveness block, face match, proof-of-address result with the canonical address fields, AML hits, database-validation outcome. Use this for audit-pack export and for rendering the applicant status in your letting-agent dashboard.

STEP 5 — Decide

  Branch logic:
    Approved    → forward the pack to the landlord, advance to lease signing.
    In Review   → hold the application, wait for analyst webhook update.
    Declined    → refuse the application, log the decline reason.
    Resubmitted → applicant updated something; re-read the decision.

  For Database Validation specifically — if the result indicates an expired Right to Rent share code, ask the applicant for a fresh one before moving forward.

STEP 6 — Ongoing monitoring (long leases)

  For multi-year tenancies, enable Ongoing AML at $0.07/user/year. The session status updates automatically when the tenant lands on a new sanctions list or document expirations approach (passport, visa, residency permit). 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.
  - data.updated — session data changed (resubmission, expiry, ongoing AML hit).

  Verify X-Signature-V2 on every payload. The webhook secret is per-environment — sandbox key is separate from production.

CONSTRAINTS
  - Session statuses use Title Case With Spaces (Approved, In Review).
  - Default record retention is 5 years per tenant per the EU AML package; UK Right to Rent requires document copies for the tenancy duration + one year.
  - The address on the Proof of Address document MUST match the address on the underlying ID for an Approved outcome; if they differ, the session flips to In Review.

FAQ

常见问题

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 does tenant screening actually involve?

It's the process a landlord or letting agent runs before handing over the keys, to make sure the applicant is who they say they are and can lawfully take the lease. The standard pieces are:

  • Identity verification, government ID + face match + liveness, so you know the person on the phone is the person on the application
  • Address proof, a recent utility bill, bank statement, or government letter showing where they currently live
  • Lease eligibility, country-specific. In the UK that's Right to Rent. In the EU it's a residency document. In the US it's typically a state-of-residence + SSN. In Latin America it's the national tax id.
  • Anti-money-laundering screen, sanctions, Politically Exposed Persons (PEP), adverse media
  • (Optional) income and guarantor evidence, payslips, bank statements, plus a linked KYC on the guarantor when affordability is on the edge

Didit ships all of it as one hosted flow. The applicant completes it on their phone in under five minutes; the agent gets a signed pack back.

Who actually needs to do this?

Anyone leasing residential property to a third party. In practice that means:

  • Build-to-rent operators, Greystar, Equity Residential, Mileway, Quintain archetype
  • Letting agents, Foxtons, Belvoir, Connells, Re/Max
  • PropTech platforms, SpareRoom, Goodlord, Canopy, OpenRent
  • Short-let and co-living, The Collective, Common, Outsite
  • Corporate housing and student PBSA, Unite Students, Vita, Sonder

In the UK, Right to Rent checks are a hard legal requirement under the Immigration Act, with material per-tenant fines for failing to perform them. The EU has parallel obligations under the AML package for any property professional. The US runs it through state landlord-tenant law plus fair-housing rules.

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.

What goes wrong if a landlord skips this?

Three things, in order of how often they bite:

  • Fraud applicants, fake IDs, photoshopped payslips, applicants impersonating someone with better credit. The landlord loses the rent and the property sits empty during the eviction.
  • Right-to-Rent penalty, in the UK, up to £20,000 per tenant for renting to someone without the right immigration status. Criminal liability for repeat offenders.
  • AML reporting failures, large cash deposits or sanctioned tenants without a filed Suspicious Activity Report (SAR) creates regulator exposure under the EU AML package and the UK Money Laundering Regulations.

The traditional paper-based check is slow, expensive (typically £15-£40 per applicant through legacy providers), and easy to forge. Most agents end up doing a partial check and hoping for the best. Didit eliminates the trade-off, full coverage at $0.53 per applicant (KYC bundle + Proof of Address).

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.

How are addresses cross-checked?

Three layers of validation run on every Proof of Address upload:

  • OCR extraction, the bill / statement / letter is read and the address is parsed into the canonical address fields (line 1, city, postal code, country)
  • ID cross-check, the extracted address is compared with the address on the underlying ID document. A close match passes; a different city or postal code flips the session to In Review.
  • Registry validation (where available), the address is looked up against the country's authoritative source, UK Royal Mail PAF, Spain Catastro, US USPS, France BAN, etc.

Fraud patterns Didit catches: a Photoshopped utility bill with a forged address, a real bill from a different building, a bill belonging to a different person at the same address, an expired bill (over 90 days old). All three layers run server-side; the agent never sees a raw upload, only the validated result.

What does ongoing monitoring look like?

Verification at the start of the tenancy is necessary but not sufficient, for long leases, tenants change circumstances and sanctions lists update daily. Didit's ongoing monitoring catches:

  • Ongoing AML on the tenant, daily delta refresh at $0.07 per tenant per year
  • Visa / residency permit expiry, fires a webhook 30 days before the document expires so the agent can request a fresh share code
  • New sanctions listing, instant webhook the day the tenant lands on a new list
  • Address change (resubmission), if the tenant updates their address mid-tenancy, the new proof is automatically run through the same validation stack

Everything flows through the same status.updated webhook you wired for onboarding. No new endpoint, no extra integration.

How does Didit compare on price?

Most tenant-screening providers price between £15 and £40 per applicant, Goodlord, Letting a Property, Open Banking-based affordability tools. Most charge per check, plus a per-tenancy admin fee, plus a per-Right-to-Rent surcharge.

Didit's published price is $0.33 for the KYC bundle + $0.20 for Proof of Address = $0.53 per applicant. Database Validation is variable per jurisdiction and typically adds $0.05-$0.20 depending on the service. No floor, no commit, no per-country surcharge.

That's roughly 10× cheaper than the incumbent stack on the same legal output. At a 200-tenant build-to-rent portfolio that turns over once a year, the saving is around £3,000 in screening costs, and the applicant experience is faster, with no paper, no scanning. Full pricing at /pricing.
