Automating Genesys Cloud Recording URL Rotation with Python and Event Streams

What You Will Build

• One sentence: what the code does when it is working. The script automatically fetches conversation recordings, validates pre-signed download URL expiration against organizational constraints, refreshes URLs before TTL expiration, syncs refresh events to external storage via webhooks, and generates compliance audit logs.
• One sentence: which API/SDK this uses. It uses the Genesys Cloud Conversations API, Media Recordings API, and Event Streams Webhooks API alongside the official genesys_cloud_sdk.
• One sentence: the programming language(s) covered. Implemented in Python 3.10+ using httpx, pydantic, and tenacity.

Prerequisites

• OAuth client type: Service Account or Client Credentials flow
• Required scopes: conversations:view, media:recordings:view, webhooks:manage, webhooks:read
• SDK version: genesys-cloud-py-sdk>=1.0.0
• Language/runtime requirements: Python 3.10+, asyncio compatible environment
• External dependencies: pip install httpx tenacity pydantic python-dotenv

Authentication Setup

Genesys Cloud requires OAuth 2.0 Client Credentials for server-to-server integration. The following code establishes a persistent session with automatic token refresh and scopes validation.

import os
import httpx
import asyncio
from typing import Dict, Optional
from pydantic import BaseModel

class OAuthConfig(BaseModel):
    client_id: str
    client_secret: str
    base_url: str
    scopes: list[str] = ["conversations:view", "media:recordings:view"]

class TokenManager:
    def __init__(self, config: OAuthConfig):
        self.config = config
        self.access_token: Optional[str] = None
        self.expires_at: float = 0.0
        self.client = httpx.AsyncClient(base_url=config.base_url, timeout=30.0)

    async def authenticate(self) -> str:
        """Executes Client Credentials OAuth flow and caches the token."""
        if self.access_token and asyncio.get_event_loop().time() < self.expires_at:
            return self.access_token

        response = await self.client.post(
            "/oauth/token",
            data={
                "grant_type": "client_credentials",
                "scope": " ".join(self.config.scopes),
                "client_id": self.config.client_id,
                "client_secret": self.config.client_secret
            }
        )
        response.raise_for_status()
        payload = response.json()
        
        self.access_token = payload["access_token"]
        self.expires_at = asyncio.get_event_loop().time() + payload["expires_in"] - 30
        return self.access_token

    async def get_headers(self) -> Dict[str, str]:
        token = await self.authenticate()
        return {
            "Authorization": f"Bearer {token}",
            "Content-Type": "application/json",
            "Accept": "application/json"
        }

    async def close(self):
        await self.client.aclose()

Implementation

Step 1: Fetch Recording Blob Reference and Validate Constraints

The Conversations API returns a list of recordings attached to a conversation. Each recording object contains a download_url with an embedded expiration timestamp. You must validate the URL against maximum_refresh_ttl_seconds and organizational storage constraints before attempting rotation.

import time
import logging
from typing import List, Optional
from pydantic import BaseModel, Field
import httpx

logging.basicConfig(level=logging.INFO, format="%(asctime)s - %(levelname)s - %(message)s")
logger = logging.getLogger("blob_rotator")

class RecordingConstraint(BaseModel):
    maximum_refresh_ttl_seconds: int = Field(default=300, ge=60, le=3600)
    storage_quota_mb: int = Field(default=10240)
    allowed_formats: List[str] = Field(default=["wav", "mp3"])

class RecordingBlob(BaseModel):
    recording_id: str
    download_url: str
    format: str
    size_bytes: int
    expires_at: Optional[float] = None
    is_expired: bool = False

async def fetch_and_validate_recordings(
    token_mgr: TokenManager,
    conversation_id: str,
    constraints: RecordingConstraint
) -> List[RecordingBlob]:
    """
    Fetches recordings for a conversation and validates against constraints.
    Real endpoint: GET /api/v2/conversations/{conversationId}/recordings
    Scope required: conversations:view, media:recordings:view
    """
    headers = await token_mgr.get_headers()
    base = token_mgr.config.base_url
    
    # HTTP Request Cycle Example
    # GET /api/v2/conversations/{conversationId}/recordings
    # Headers: Authorization: Bearer <token>, Accept: application/json
    # Response: { "entities": [ { "id": "rec-123", "download_url": "https://...", "format": "wav", "size": 1048576, "expires_at": "2023-10-01T12:00:00Z" } ] }
    
    async with httpx.AsyncClient(timeout=30.0) as client:
        response = await client.get(
            f"{base}/api/v2/conversations/{conversation_id}/recordings",
            headers=headers
        )
        
        if response.status_code == 401:
            raise PermissionError("OAuth token invalid or expired. Refresh required.")
        if response.status_code == 403:
            raise PermissionError("Missing required scopes: conversations:view or media:recordings:view")
        if response.status_code == 429:
            retry_after = int(response.headers.get("Retry-After", 5))
            logger.warning("Rate limited. Waiting %d seconds.", retry_after)
            await asyncio.sleep(retry_after)
            return await fetch_and_validate_recordings(token_mgr, conversation_id, constraints)
            
        response.raise_for_status()
        data = response.json()
        
    validated_blobs: List[RecordingBlob] = []
    current_time = time.time()
    
    for entity in data.get("entities", []):
        expires_ts = time.mktime(time.strptime(entity.get("expires_at", ""), "%Y-%m-%dT%H:%M:%S%z")) if entity.get("expires_at") else None
        is_expired = bool(expires_ts and current_time >= expires_ts)
        
        # Constraint validation
        if entity.get("format") not in constraints.allowed_formats:
            logger.warning("Recording %s format %s not in allowed list. Skipping.", entity["id"], entity["format"])
            continue
            
        size_mb = entity.get("size", 0) / (1024 * 1024)
        if size_mb > constraints.storage_quota_mb:
            logger.warning("Recording %s exceeds storage quota. Skipping.", entity["id"])
            continue
            
        validated_blobs.append(RecordingBlob(
            recording_id=entity["id"],
            download_url=entity["download_url"],
            format=entity.get("format", "wav"),
            size_bytes=entity.get("size", 0),
            expires_at=expires_ts,
            is_expired=is_expired
        ))
        
    return validated_blobs

Step 2: Construct Refresh Payload and Execute Atomic Rotation

Genesys Cloud generates pre-signed URLs server-side. You cannot manually calculate the signature. Rotation requires an atomic HTTP POST to the recordings endpoint or a fresh GET request to trigger URL regeneration. This step implements the refresh directive, handles access-policy evaluation, and executes the rotation with retry logic.

from tenacity import retry, stop_after_attempt, wait_exponential, retry_if_exception_type
import uuid

class RotationMetrics(BaseModel):
    total_attempts: int = 0
    successful_rotations: int = 0
    failed_rotations: int = 0
    average_latency_ms: float = 0.0
    latency_samples: List[float] = Field(default_factory=list)

@retry(
    stop=stop_after_attempt(3),
    wait=wait_exponential(multiplier=1, min=2, max=10),
    retry=retry_if_exception_type((httpx.HTTPStatusError, ConnectionError))
)
async def refresh_recording_url(
    token_mgr: TokenManager,
    recording_id: str,
    metrics: RotationMetrics
) -> str:
    """
    Triggers URL regeneration by re-fetching recording metadata.
    Real endpoint: GET /api/v2/media/recordings/{recordingId}
    Scope required: media:recordings:view
    """
    start_time = time.perf_counter()
    metrics.total_attempts += 1
    headers = await token_mgr.get_headers()
    base = token_mgr.config.base_url
    
    async with httpx.AsyncClient(timeout=30.0) as client:
        response = await client.get(
            f"{base}/api/v2/media/recordings/{recording_id}",
            headers=headers
        )
        
        if response.status_code == 403:
            raise PermissionError("Access policy denied. Verify IAM role and media:recordings:view scope.")
        if response.status_code == 404:
            raise ValueError(f"Recording {recording_id} not found. Conversation may have been purged.")
        if response.status_code == 429:
            raise httpx.HTTPStatusError("Rate limit exceeded", request=response.request, response=response)
            
        response.raise_for_status()
        payload = response.json()
        
    end_time = time.perf_counter()
    latency_ms = (end_time - start_time) * 1000
    metrics.latency_samples.append(latency_ms)
    metrics.average_latency_ms = sum(metrics.latency_samples) / len(metrics.latency_samples)
    metrics.successful_rotations += 1
    
    new_url = payload.get("download_url")
    if not new_url:
        raise ValueError("Server returned recording metadata without a download_url. Format verification failed.")
        
    logger.info("Successfully rotated URL for %s. Latency: %.2fms", recording_id, latency_ms)
    return new_url

Step 3: Sync Refresh Events via Webhooks and Generate Audit Logs

After rotation, you must synchronize the event with external blob storage and emit governance logs. This step constructs the webhook payload, verifies delivery, and writes structured audit records.

import json
from datetime import datetime, timezone

class AuditLogger:
    def __init__(self, log_file: str = "rotation_audit.log"):
        self.log_file = log_file

    def write(self, recording_id: str, action: str, status: str, url: str, latency_ms: float):
        record = {
            "timestamp": datetime.now(timezone.utc).isoformat(),
            "recording_id": recording_id,
            "action": action,
            "status": status,
            "url_hash": url[-16:],  # Partial hash for security
            "latency_ms": latency_ms,
            "session_id": str(uuid.uuid4())
        }
        with open(self.log_file, "a", encoding="utf-8") as f:
            f.write(json.dumps(record) + "\n")
        logger.info("Audit log written: %s", record["action"])

async def sync_webhook(
    token_mgr: TokenManager,
    webhook_url: str,
    recording_id: str,
    new_url: str,
    latency_ms: float
) -> bool:
    """
    Posts refresh event to external storage webhook.
    Real endpoint: Custom HTTPS endpoint configured via /api/v2/webhooks
    """
    payload = {
        "event_type": "recording.url.refreshed",
        "recording_id": recording_id,
        "download_url": new_url,
        "refresh_latency_ms": latency_ms,
        "sync_timestamp": datetime.now(timezone.utc).isoformat()
    }
    
    async with httpx.AsyncClient(timeout=15.0) as client:
        try:
            response = await client.post(
                webhook_url,
                json=payload,
                headers={"Content-Type": "application/json"}
            )
            response.raise_for_status()
            logger.info("Webhook sync successful for %s", recording_id)
            return True
        except httpx.HTTPStatusError as e:
            logger.error("Webhook sync failed: %d %s", e.response.status_code, e.response.text)
            return False
        except Exception as e:
            logger.error("Webhook delivery error: %s", str(e))
            return False

Common Errors & Debugging

Error: HTTP 401 Unauthorized

• Cause: OAuth token expired, client credentials incorrect, or token cache not refreshed before request.
• Fix: Verify GENESYS_CLIENT_ID and GENESYS_CLIENT_SECRET. Ensure TokenManager.authenticate() runs before every API call. Check that the token expiration buffer (30 seconds) is sufficient for your environment.
• Code showing the fix: The TokenManager already implements time-based cache invalidation. If you receive a 401 during a batch operation, force a refresh by calling await token_mgr.authenticate() explicitly before the next request.

Error: HTTP 403 Forbidden

• Cause: Missing OAuth scopes or insufficient IAM role permissions for the service account.
• Fix: Assign conversations:view and media:recordings:view to the OAuth client. Verify the service account user has a role with View recordings and View conversations permissions in the Genesys Cloud Admin console.
• Code showing the fix: Update the OAuthConfig scopes list and re-authenticate:

  config = OAuthConfig(client_id=..., client_secret=..., scopes=["conversations:view", "media:recordings:view"])
  

Error: HTTP 429 Too Many Requests

• Cause: Rate limit cascade triggered by rapid polling or concurrent rotation requests across multiple conversations.
• Fix: Implement exponential backoff. The tenacity decorator in refresh_recording_url handles automatic retries. For bulk operations, add a delay between conversation queries.
• Code showing the fix: The @retry configuration already applies wait_exponential(multiplier=1, min=2, max=10). Increase max to 30 if operating at high scale.

Error: Storage Quota or Format Verification Failure

• Cause: Recording exceeds storage_quota_mb or uses an unsupported codec.
• Fix: Adjust RecordingConstraint thresholds or filter conversations before rotation. Genesys Cloud enforces org-level media limits; verify your organization has available storage.
• Code showing the fix: Modify the constraint validation block to log warnings instead of skipping, or dynamically adjust quotas per environment.
