+## Daily.co Webhook Integration
+
+### Webhook Configuration
+
+Daily.co webhooks are configured via API (no dashboard interface). Use the Daily.co REST API to set up webhook endpoints:
+
+```bash
+# Configure webhook endpoint
+curl -X POST https://api.daily.co/v1/webhook-endpoints \
+  -H "Authorization: Bearer ${DAILY_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://yourdomain.com/v1/daily_webhook",
+    "events": [
+      "participant.joined",
+      "participant.left",
+      "recording.started",
+      "recording.ready-to-download",
+      "recording.error"
+    ]
+  }'
+```
+
+### Webhook Event Examples
+
+**Participant Joined:**
+```json
+{
+  "type": "participant.joined",
+  "id": "evt_participant_joined_1640995200",
+  "ts": 1640995200000,
+  "data": {
+    "room": {"name": "test-room-123-abc"},
+    "participant": {
+      "id": "participant-123",
+      "user_name": "John Doe",
+      "session_id": "session-456"
+    }
+  }
+}
+```
+
+**Recording Ready:**
+```json
+{
+  "type": "recording.ready-to-download",
+  "id": "evt_recording_ready_1640995200",
+  "ts": 1640995200000,
+  "data": {
+    "room": {"name": "test-room-123-abc"},
+    "recording": {
+      "id": "recording-789",
+      "status": "finished",
+      "download_url": "https://bucket.s3.amazonaws.com/recording.mp4",
+      "start_time": "2025-01-01T10:00:00Z",
+      "duration": 1800
+    }
+  }
+}
+```
+
+### Webhook Signature Verification
+
+Daily.co uses HMAC-SHA256 for webhook verification:
+
+```python
+import hmac
+import hashlib
+
+def verify_daily_webhook(body: bytes, signature: str, secret: str) -> bool:
+    expected = hmac.new(secret.encode(), body, hashlib.sha256).hexdigest()
+    return hmac.compare_digest(expected, signature)
+```
+
+Signature is sent in the `X-Daily-Signature` header.
+
+### Recording Processing Flow
+
+1. **Daily.co Meeting Ends** → Recording processed
+2. **Webhook Fired** → `recording.ready-to-download` event
+3. **Webhook Handler** → Extracts download URL and recording ID
+4. **Background Task** → `process_recording_from_url.delay()` queued
+5. **Download & Process** → Audio downloaded, validated, transcribed
+6. **ML Pipeline** → Same processing as Whereby recordings
+
+```python
+# New Celery task for Daily.co recordings
+@shared_task
+@asynctask
+async def process_recording_from_url(recording_url: str, meeting_id: str, recording_id: str):
+    # Downloads from Daily.co URL → Creates transcript → Triggers ML pipeline
+    # Identical processing to S3-based recordings after download
+```
