End-to-end Know Your Customer (KYC) verification. This skill creates a KYC workflow, generates a session URL where a real user completes ID scan + selfie + face match, and retrieves the verification decision.

What the user experiences:

• Receives a verification link
• Scans their ID document (passport, ID card, driver's license)
• Takes a live selfie
• System auto-matches selfie to document photo
• Gets approved, declined, or flagged for review

Authentication

All requests require x-api-key header. Get your key from Didit Business Console → API & Webhooks, or via programmatic registration (see below).

Getting Started (No Account Yet?)

If you don't have a Didit API key, create one in 2 API calls:

• Register: POST https://apx.didit.me/auth/v2/programmatic/register/ with {"email": "you@gmail.com", "password": "MyStr0ng!Pass"}
• Check email for a 6-character OTP code
• Verify: POST https://apx.didit.me/auth/v2/programmatic/verify-email/ with {"email": "you@gmail.com", "code": "A3K9F2"} → response includes api_key

To add credits: GET /v3/billing/balance/ to check, POST /v3/billing/top-up/ with {"amount_in_dollars": 50} for a Stripe checkout link.

See the didit-verification-management skill for full platform management (workflows, sessions, users, billing).

Quick Start — KYC in 3 API Calls

import requests, time
API_KEY = "your_api_key"
headers = {"x-api-key": API_KEY, "Content-Type": "application/json"}
BASE = "https://verification.didit.me/v3"
# 1. Create a KYC workflow (one-time setup — reuse the workflow_id for all users)
workflow = requests.post(f"{BASE}/workflows/", headers=headers, json={
    "workflow_label": "KYC Onboarding",
    "workflow_type": "kyc",
    "is_liveness_enabled": True,
    "is_face_match_enabled": True,
    "face_match_score_decline_threshold": 50,
    "max_retry_attempts": 3,
}).json()
workflow_id = workflow["uuid"]
# 2. Create a session for a specific user
session = requests.post(f"{BASE}/session/", headers=headers, json={
    "workflow_id": workflow_id,
    "vendor_data": "user-abc-123",
    "callback": "https://yourapp.com/verification-done",
    "language": "en",
}).json()
print(f"Send user to: {session['url']}")
# User opens this URL → scans ID → takes selfie → done
# 3. Poll for the decision (or use webhooks)
while True:
    decision = requests.get(
        f"{BASE}/session/{session['session_id']}/decision/",
        headers={"x-api-key": API_KEY},
    ).json()
    status = decision["status"]
    if status in ("Approved", "Declined", "In Review"):
        break
    time.sleep(10)
print(f"Result: {status}")
if status == "Approved":
    id_data = decision["id_verifications"][0]
    print(f"Name: {id_data['first_name']} {id_data['last_name']}")
    print(f"DOB: {id_data['date_of_birth']}")
    print(f"Document: {id_data['document_type']} ({id_data['issuing_country']})")

Step 1: Create a KYC Workflow

A workflow defines what checks run. Create one per use case and reuse it for all users.

POST https://verification.didit.me/v3/workflows/

API Reference: https://docs.didit.me/management-api/workflows/create

Recommended KYC Configuration

Response

{
  "uuid": "d8d2fa2d-c69c-471c-b7bc-bc71512b43ef",
  "workflow_label": "KYC Onboarding",
  "workflow_type": "kyc",
  "features": ["ocr", "liveness", "face_match"],
  "total_price": "0.10",
  "workflow_url": "https://verify.didit.me/..."
}

Save uuid as your workflow_id.

Step 2: Create a Session for Each User

Each user gets their own session. The session generates a unique URL where they complete verification.

POST https://verification.didit.me/v3/session/

API Reference: https://docs.didit.me/sessions-api/create-session

Key Parameters

Response

{
  "session_id": "11111111-2222-3333-4444-555555555555",
  "session_token": "abcdef123456",
  "url": "https://verify.didit.me/session/abcdef123456",
  "status": "Not Started",
  "workflow_id": "d8d2fa2d-..."
}

Send the user to url — this is where they complete verification (web or mobile).

Step 3: Get the Decision

After the user completes verification, retrieve the results.

GET https://verification.didit.me/v3/session/{sessionId}/decision/

API Reference: https://docs.didit.me/sessions-api/retrieve-session

Two Ways to Know When It's Ready

Option A: Webhooks (recommended for production) Configure a webhook URL in Business Console → API & Webhooks. Didit sends a POST with session_id and status when the decision is ready.

Option B: Polling Poll GET /v3/session/{id}/decision/ every 10–30 seconds. Check status — stop when it's Approved, Declined, or In Review.
