### Get Live-Capture Selfie URL

Source: https://idswyft.app/docs

Returns a short-lived signed URL for the verification's live-capture selfie. This is useful for downstream face matching on your own systems. The URL is scoped to the authenticated API key and returns a 404 for unknown verification IDs.

```APIDOC
## GET /api/v2/verify/:id/selfie

### Description
Returns a short-lived **signed URL** for the verification's live-capture selfie — handy when you want to run a downstream face match on your own side. Scoped to the authenticated API key: a verification you don't own (or an unknown ID) returns `404` (never 403), so the endpoint can't be used to enumerate other developers' verification IDs. Returns only the selfie URL — no OCR, PII, or other documents.

### Endpoint
`/api/v2/verify/:id/selfie`

### Method
GET

### Parameters
#### Query Parameters
- **X-API-Key** (string) - Required - Your API key for authentication.

### Request Example
```bash
curl -X GET https://api.idswyft.app/api/v2/verify/550e8400-e29b-41d4-a716-446655440001/selfie \
  -H "X-API-Key: your-key"
```

### Response
#### Success Response (200)
- **verification_id** (string) - The unique identifier for the verification.
- **selfie_url** (string) - A short-lived signed URL pointing to the selfie image.
- **expires_in** (integer) - The time in seconds until the selfie URL expires.

### Response Example
```json
{
  "verification_id": "550e8400-e29b-41d4-a716-446655440001",
  "selfie_url": "https://storage.idswyft.app/selfies/…?token=…",
  "expires_in": 300
}
```

### JavaScript: Complete ID Verification Flow

Source: https://idswyft.app/docs

This comprehensive JavaScript snippet demonstrates the entire ID verification process using the IDSWYFT API. It covers starting a session, uploading front and back documents, polling for OCR and cross-validation completion, submitting a live capture, and finally polling for the overall verification result. Ensure you replace 'your-api-key' with your actual API key and provide the correct file objects for documents and captures.

```javascript
const BASE = 'https://api.idswyft.app';
const KEY = 'your-api-key';
const headers = { 'X-API-Key': KEY };

// ─── 1. Start session ───────────────────────────────────────────
const { verification_id } = await fetch(`${BASE}/api/v2/verify/initialize`, {
 method: 'POST',
 headers: { ...headers, 'Content-Type': 'application/json' },
 body: JSON.stringify({ user_id: 'user-uuid' }),
}).then(r => r.json());

// ─── 2. Upload front document ───────────────────────────────────
const fd1 = new FormData();
fd1.append('document_type', 'drivers_license');
fd1.append('document', frontFile); // File from <input type="file">
await fetch(`${BASE}/api/v2/verify/${verification_id}/front-document`, { method: 'POST', headers, body: fd1 });

// ─── 3. Poll until OCR finishes ─────────────────────────────────
let r;
do {
 await new Promise(ok => setTimeout(ok, 2000));
 r = await fetch(`${BASE}/api/v2/verify/${verification_id}/status`, { headers }).then(r => r.json());
} while (!r.ocr_data);

// ─── 4. Upload back-of-ID (cross-validation auto-triggers) ──────
const fd2 = new FormData();
fd2.append('document_type', 'drivers_license');
fd2.append('document', backFile); // field name is 'document' (not 'back_of_id')
await fetch(`${BASE}/api/v2/verify/${verification_id}/back-document`, { method: 'POST', headers, body: fd2 });

// ─── 5. Poll until cross-validation finishes ────────────────────
do {
 await new Promise(ok => setTimeout(ok, 2000));
 r = await fetch(`${BASE}/api/v2/verify/${verification_id}/status`, { headers }).then(r => r.json());
} while (!r.cross_validation_results);

if (r.final_result === 'failed') throw new Error('Cross-validation failed: ' + r.failure_reason);

// ─── 6. Submit live capture (file upload) ────────────────────────
const fd3 = new FormData();
fd3.append('selfie', captureBlob, 'capture.jpg'); // Blob from canvas.toBlob()
await fetch(`${BASE}/api/v2/verify/${verification_id}/live-capture`, {
 method: 'POST',
 headers,
 body: fd3,
});

// ─── 7. Poll for final result ────────────────────────────────────
do {
 await new Promise(ok => setTimeout(ok, 2000));
 r = await fetch(`${BASE}/api/v2/verify/${verification_id}/status`, { headers }).then(r => r.json());
} while (!r.final_result);

console.log(r.final_result); // 'verified' | 'failed' | 'manual_review'
console.log(r.face_match_results?.similarity_score); // 0.0 – 1.0
console.log(r.ocr_data.name); // "Jane Smith"

```

### Submit Head-Turn Liveness Capture - cURL

Source: https://idswyft.app/docs

Use this endpoint to submit selfie frames for head-turn liveness detection. Ensure the `liveness_metadata` matches the expected schema; otherwise, a HTTP 400 error will be returned. Head-turn liveness is recommended for production identity verification.

```bash
curl -X POST https://api.idswyft.app/api/v2/verify/VERIFICATION_ID/live-capture \
  -H "X-API-Key: your-key" \
  -F "selfie=@capture.jpg" \
  -F 'liveness_metadata={
  "challenge_type": "head_turn",
  "challenge_direction": "left",
  "frames": [
  {"frame_base64":"<base64>","timestamp":1000,"phase":"turn1_start"},
  {"frame_base64":"<base64>","timestamp":4000,"phase":"turn1_peak"},
  {"frame_base64":"<base64>","timestamp":7000,"phase":"turn1_return"},
  {"frame_base64":"<base64>","timestamp":8200,"phase":"turn_start"},
  {"frame_base64":"<base64>","timestamp":11200,"phase":"turn_peak"},
  {"frame_base64":"<base64>","timestamp":14200,"phase":"turn_return"}
  ],
  "start_timestamp": 0,
  "end_timestamp": 15000
  }'
```

--------------------------------

### Submit Live Capture - Passive Mode - cURL

Source: https://idswyft.app/docs

Upload a selfie for passive liveness detection. This mode uses heuristic signals and does not require additional metadata. Ensure the image is a live capture from the device camera, not a static file upload.

```bash
# Passive liveness (just the file, no metadata)
curl -X POST https://api.idswyft.app/api/v2/verify/VERIFICATION_ID/live-capture \
  -H "X-API-Key: your-key" \
  -F "selfie=@capture.jpg"
```

--------------------------------

### POST /api/v2/verify/:id/back-document

Source: https://idswyft.app/docs

Uploads the back face of an identity document. This step is required to unlock live capture and performs cross-validation against the front document's data.

```APIDOC
## POST /api/v2/verify/:id/back-document

### Description
Upload the **back face** of the ID for barcode/QR scanning and cross-validation against the front OCR data. This is a **required step** — it unlocks live capture. If the front and back do not match the same document, the verification immediately moves to failed and live capture is blocked.

What cross-validation checks:
✓ PDF417 / QR barcode decoding
✓ ID number consistency (front OCR ↔ barcode)
✓ Expiry date matching
✓ Issuing authority matching
✓ Photo consistency score
✓ Security feature detection

### Method
POST

### Endpoint
`/api/v2/verify/:id/back-document`

### Parameters
#### Path Parameters
- **id** (string) - Required - The unique identifier for the verification session.

#### Request Body
- **document_type** (string) - Required - Must match the `document_type` used in Step 2 (front-document upload).
- **document** (File) - Required - The document image file (JPEG, PNG, or WebP). Max 10 MB. Field name is 'document'.

### Request Example
```bash
curl -X POST https://api.idswyft.app/api/v2/verify/550e8400-e29b-41d4-a716-446655440001/back-document \
  -H "X-API-Key: your-key" \
  -F "document_type=drivers_license" \
  -F "document=@back.jpg"
```

### Response
(Response details for this endpoint are not fully provided in the source text, but typically include success status, verification ID, and updated session status.)
```

--------------------------------

### Upload Back Document
