Didit 身份验证, 证件采集、OCR 和真实性在线检查。

全球覆盖

14,000+ 种证件。
220+ 个国家/地区。

西班牙 DNI、日本 My Number、英国护照。每月新增证件, 每次检查 $0.15，结果格式一致，2 秒内响应。

工作原理

从注册到验证用户，仅需四步。

  1. 步骤 01

    创建工作流程

    选择您需要的检查项, 身份、活体、人脸比对、制裁名单、地址、年龄、电话、邮箱、自定义问题。在控制台中将它们拖入流程，或通过 API 发布相同流程。支持条件分支、A/B 测试，无需代码。

  2. 步骤 02

    集成

    通过我们的 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 等方式向用户发送链接。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、光线提示、移动端切换和无障碍功能。在用户进行流程时，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。两秒内出结果。

  4. 步骤 04

    接收结果

    实时签名 Webhook 可在用户通过、拒绝或发送审核时立即同步您的数据库。可按需轮询 API。或打开控制台检查每个会话、每个信号，并按您的方式管理案例。

专为开发者打造 · 致力于防欺诈 · 开放式设计

六项功能。一个功能标志。ID_VERIFICATION。

以下所有功能都在同一模块中切换。没有升级层级，没有单独的 SKU，没有附加调用。在控制台中按工作流程开启，或在调用独立端点时内联传递。
阅读文档获取 API 密钥
01 · 覆盖范围

220+ 国家/地区。14,000+ 证件类型。

支持护照、身份证、驾驶证、居住证等。涵盖 130 多种语言、50 多种文字（拉丁文、阿拉伯文、西里尔文、CJK、天城文、希伯来文、泰文、格鲁吉亚文）。每月新增证件类型。可按国家/地区进行子类型控制, 例如，根据政策要求，可单独接受印第安纳州操作员执照和纽约州增强型驾照。
02 · 数据提取

视觉字段、MRZ 和条形码, 交叉核对。

一次性提取所有视觉信息、MRZ（机器可读区）和条形码字段。在响应离开我们的边缘网络之前，这三者会进行交叉核对。不一致之处会以警告形式显示，以便您将案件转交人工审核。
03 · 真实性

证件真实。肖像完整。无屏幕截图。

与认证数据库进行模板匹配。全息图和微缩文字检测。肖像完整性检查。证件活体检测可有效抵御四种常见攻击：屏幕截图、手机照片、打印件以及在真实证件上替换肖像。
04 · 拍摄质量

在进入审核前，拒绝模糊和眩光。

每次提交的焦距、亮度和分辨率得分均为 0-100，并提供加权总分。超出边框的角落和过度曝光的侧面会明确标记。可调整的阈值可预先拒绝低质量的拍摄，确保它们不会进入您的人工审核队列。
05 · 风险策略

决策。审核。批准。按风险。按应用。

所有风险类别, 重复用户、无效 MRZ、数据不一致、证件活体度低, 均可映射到拒绝、审核或批准。可针对每个应用、国家/地区和证件类型调整策略。自动拒绝触发器（过期、黑名单、不支持）无论您的设置如何都会强制执行。
06 · 持续 KYC

证件会过期。在监管机构发现之前及时处理。

我们会跟踪您存储的每个证件的有效期。当证件过期时，用户的 KYC 状态会自动翻转，并通过 webhook 通知您。无需批处理，无需季度重新入职冲刺, KYC 刷新持续进行，确保您始终符合 AML 指令。
集成

两个端点。相同的 JSON。相同的价格。

当您希望我们的托管 UI 处理采集时，创建会话；当您已有图像时，调用独立端点。两者都返回相同的 id_verification 报告。
POST /v3/session/托管 UI
$ curl -X POST https://verification.didit.me/v3/session/ \

# Didit ID Verification — integrate in 5 minutes

You are integrating Didit's ID Verification 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, lighting cues, retries,
mobile handoff, and accessibility for you.

1. Create a workflow that contains the ID_VERIFICATION 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: "ID_VERIFICATION" }   (UPPERCASE — strict enum)

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 the document image (mobile SDK capture, native
onboarding app, reseller pipeline).

POST https://verification.didit.me/v3/id-verification/
Content-Type: multipart/form-data
Body fields:
  - front_image  (required, file)
  - back_image   (optional, file)
  - vendor_data  (optional string, your user id)

Response: JSON report with extracted fields, image quality scores,
warnings array, and the verdict.

## 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", "kyc_expired"]
- 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 id_verification object includes:
- status: "Approved" | "Declined" | "In Review" | "Expired" | "Not Finished"
- document_type: "Passport" | "Identity Card" | "Driver's License" | "Residence Permit" | null
- document_number, personal_number
- front_image, back_image, portrait_image (signed URLs, expire in 1 hour)
- date_of_birth (YYYY-MM-DD), age (number)
- expiration_date, date_of_issue (YYYY-MM-DD)
- issuing_state, issuing_state_name (ISO 3166-1 alpha-3 + display name)
- first_name, last_name, full_name
- gender ("M" | "F" | "U"), nationality (ISO 3166-1 alpha-3)
- address, formatted_address, parsed_address (street_1, street_2, city,
  region, postal_code, geometry { lat, lng })
- front_image_quality_score / back_image_quality_score (focus, brightness,
  resolution, overall, each 0-100)
- warnings: Array<{ risk, log_type, short_description, long_description }>

## 5. Hard rules — do not change
- Base URL for /v3/* endpoints is verification.didit.me (NOT apx.didit.me).
- Feature enum is UPPERCASE: ID_VERIFICATION, LIVENESS, FACE_MATCH, AML, IP_ANALYSIS.
- 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",
  "Expired", "Not Finished" (title-cased, space-separated).

## 6. Pricing reference (public)
- Path A bundled in a full KYC workflow: $0.33 per session
- Path B standalone /v3/id-verification/ call: $0.15 per call
- 500 free verifications every month, forever, on every account.

## 7. Verify your integration
- Sandbox starts on signup at https://business.didit.me — no separate flag.
- Test docs: deterministic synthetic IDs returned in sandbox.
- Switch to live: flip the application's environment toggle in console.

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.

Which document types and countries are supported?
Passports, national ID cards, driver's licenses, and residence permits across 220+ countries and territories, 14,000+ distinct document templates in total, with text recognition in 130+ languages and 50+ scripts (Latin, Arabic, Cyrillic, CJK, Devanagari, Hebrew, Thai, Georgian). The full catalog is browsable at docs.didit.me/core-technology/id-verification/supported-documents-id-verification, and the same data feeds the searchable table on this page.
What is the response shape?
A single id_verification JSON object. Top-level status is one of Approved, Declined, In Review, Expired, or Not Finished. The object also includes document_type, document_number, full_name, first_name, last_name, date_of_birth (YYYY-MM-DD), age, expiration_date, date_of_issue, issuing_state (ISO 3166-1 alpha-3), nationality, gender, address, a structured parsed_address with street, city, region, postal_code, and geometry coordinates, signed URLs for portrait_image / front_image / back_image / front_video / back_video, image quality scores for focus / brightness / resolution / overall (each 0–100), and a warnings array. Full reference at docs.didit.me/core-technology/id-verification/report-id-verification.
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 document fraud?
Five layers, every layer enabled by default: (1) template matching against the certified document database, (2) security-feature detection (holograms, microprint, watermarks), (3) tamper detection on the portrait and biographic data, (4) document liveness that rejects screen captures, printed copies, and digital edits, (5) cross-reference between visual zone, MRZ, and barcode. Auto-decline triggers, DOCUMENT_EXPIRED, MINIMUM_AGE_NOT_MET, DOCUMENT_NOT_SUPPORTED_FOR_APPLICATION, ID_DOCUMENT_IN_BLOCKLIST, PORTRAIT_IMAGE_NOT_DETECTED, stay enforced regardless of your risk policy.
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.
