Querying Genesys Cloud Recording Transcription Status with Python SDK
What You Will Build
- A production-ready polling engine that tracks Genesys Cloud recording transcription states, validates audio and language models, and triggers secure download links upon completion.
- This implementation uses the Genesys Cloud Media API (
/api/v2/media/recordings) wrapped withhttpxfor precise rate-limit control and state machine tracking. - The tutorial covers Python 3.9+ with type hints, Pydantic validation, structured audit logging, and external webhook synchronization.
Prerequisites
- OAuth Client Type: Confidential Client (Client Credentials Flow)
- Required Scopes:
media:recordings:view,media:transcriptions:view - SDK/API Version: Genesys Cloud API v2,
genesys-cloud-sdk-python>=3.0.0(concepts apply, but directhttpxcalls are used for explicit rate-limit and retry control) - Runtime: Python 3.9 or higher
- Dependencies:
pip install httpx pydantic structlog uuid
Authentication Setup
Genesys Cloud requires a bearer token for every API call. The Client Credentials flow exchanges your client ID and secret for a short-lived access token. Token caching prevents unnecessary re-authentication and reduces load on the authorization server.
import httpx
import time
from typing import Optional
class GenesysAuthManager:
def __init__(self, client_id: str, client_secret: str, base_url: str):
self.client_id = client_id
self.client_secret = client_secret
self.token_url = f"{base_url}/oauth/token"
self._access_token: Optional[str] = None
self._token_expiry: float = 0.0
def get_token(self) -> str:
if self._access_token and time.time() < self._token_expiry:
return self._access_token
payload = {
"grant_type": "client_credentials",
"client_id": self.client_id,
"client_secret": self._client_secret,
"scope": "media:recordings:view media:transcriptions:view"
}
with httpx.Client(timeout=10.0) as client:
response = client.post(
self.token_url,
data=payload,
headers={"Content-Type": "application/x-www-form-urlencoded"}
)
response.raise_for_status()
token_data = response.json()
self._access_token = token_data["access_token"]
self._token_expiry = time.time() + (token_data["expires_in"] - 30)
return self._access_token
Implementation
Step 1: Rate-Limited Client and Recording Matrix Configuration
Genesys Cloud enforces strict rate limits on the Media API. A polling loop that ignores 429 responses or Retry-After headers will cascade into exponential backoff failures. This step constructs a rate-limited HTTP client and defines the polling configuration schema.
import httpx
import time
from pydantic import BaseModel, Field
from typing import List, Dict, Any
class CheckDirective(BaseModel):
polling_interval_seconds: float = Field(5.0, ge=1.0, le=60.0)
max_polling_attempts: int = Field(120, ge=1)
rate_limit_requests_per_minute: int = Field(60, ge=10, le=300)
retry_base_delay: float = Field(1.0, gt=0.0)
max_retry_attempts: int = Field(3, ge=1)
class RecordingStatusQuerier:
def __init__(self, auth: GenesysAuthManager, directive: CheckDirective, base_url: str):
self.auth = auth
self.directive = directive
self.base_url = base_url.rstrip("/")
self.metrics: Dict[str, Any] = {
"total_checks": 0,
"successful_checks": 0,
"rate_limited_count": 0,
"total_latency_ms": 0.0,
"state_transitions": []
}
# Rate limiter state
self._request_timestamps: List[float] = []
def _enforce_rate_limit(self) -> None:
now = time.time()
window = 60.0
# Remove timestamps outside the 60-second window
self._request_timestamps = [ts for ts in self._request_timestamps if now - ts < window]
if len(self._request_timestamps) >= self.directive.rate_limit_requests_per_minute:
sleep_time = window - (now - self._request_timestamps[0])
if sleep_time > 0:
time.sleep(sleep_time)
self._request_timestamps.append(time.time())
def _get_with_retry(self, endpoint: str) -> httpx.Response:
for attempt in range(self.directive.max_retry_attempts):
self._enforce_rate_limit()
token = self.auth.get_token()
with httpx.Client(timeout=15.0) as client:
response = client.get(
f"{self.base_url}{endpoint}",
headers={
"Authorization": f"Bearer {token}",
"Accept": "application/json",
"User-Agent": "GenesysTranscriptionQuerier/1.0"
}
)
if response.status_code == 429:
retry_after = float(response.headers.get("Retry-After", self.directive.retry_base_delay * (2 ** attempt)))
self.metrics["rate_limited_count"] += 1
time.sleep(retry_after)
continue
if response.status_code == 401:
# Force token refresh
self.auth._access_token = None
continue
return response
raise httpx.HTTPStatusError("Max retries exceeded", request=response.request, response=response)

"self": {
"href": "/api/v2/media/recordings/a1b2c3d4-5678-90ab-cdef-1234567890ab"
}
}
}
Step 2: State Machine Transitions and Atomic GET Operations
The Media API returns a Recording object with discrete status fields. The state machine tracks transitions from queued to processing to complete or failed. Atomic GET operations ensure that each polling cycle fetches a fresh snapshot before evaluating state changes.
from enum import Enum
from typing import Optional, Tuple
import structlog
logger = structlog.get_logger()
class RecordingState(Enum):
QUEUED = "queued"
PROCESSING = "processing"
COMPLETE = "complete"
FAILED = "failed"
class RecordingStateTracker:
def __init__(self):
self.history: Dict[str, RecordingState] = {}
def check_transition(self, recording_id: str, new_state: RecordingState) -> bool:
previous = self.history.get(recording_id)
if previous != new_state:
self.history[recording_id] = new_state
logger.info("state_transition", recording_id=recording_id, from_state=previous, to_state=new_state)
return True
return False
def get_state(self, recording_id: str) -> Optional[RecordingState]:
return self.history.get(recording_id)
Step 3: Validation Pipelines and Download Trigger Logic
Before marking a recording as ready, the system must verify recording integrity and language model alignment. This pipeline checks audio duration, format compatibility, and transcription status. Upon successful validation, the system extracts the secure download link from the links object.
from pydantic import BaseModel, field_validator
import uuid
class RecordingValidationPipeline(BaseModel):
recording_id: str
status: str
transcription_status: str
audio_format: str
duration: float
language_code: str
links: Dict[str, Any]
@field_validator("duration")
@classmethod
def validate_duration(cls, v: float) -> float:
if v <= 0.0:
raise ValueError("Recording duration must be greater than zero")
return v
@field_validator("audio_format")
@classmethod
def validate_format(cls, v: str) -> str:
allowed = {"wav", "mp3", "ogg"}
if v.lower() not in allowed:
raise ValueError(f"Unsupported audio format: {v}")
return v.lower()
def is_transcription_ready(self) -> bool:
return (
self.status == RecordingState.COMPLETE.value and
self.transcription_status in ("complete", "partial") and
"download" in self.links
)
def get_download_url(self) -> Optional[str]:
if self.is_transcription_ready():
download_link = self.links.get("download", {})
return download_link.get("href")
return None
Step 4: Webhook Synchronization, Metrics, and Audit Logging
External analytics pipelines require synchronized status events. This step implements webhook delivery with idempotency keys, tracks polling latency, and generates structured audit logs for media governance compliance.
import json
from datetime import datetime, timezone
class MediaEventSync:
def __init__(self, webhook_url: str):
self.webhook_url = webhook_url
def post_status_event(self, recording_id: str, status: str, transcription_status: str, download_url: Optional[str], latency_ms: float) -> bool:
event_payload = {
"event_id": str(uuid.uuid4()),
"timestamp": datetime.now(timezone.utc).isoformat(),
"recording_id": recording_id,
"status": status,
"transcription_status": transcription_status,
"download_url": download_url,
"query_latency_ms": latency_ms
}
try:
with httpx.Client(timeout=10.0) as client:
response = client.post(
self.webhook_url,
json=event_payload,
headers={"Content-Type": "application/json", "X-Idempotency-Key": event_payload["event_id"]}
)
response.raise_for_status()
logger.info("webhook_sent", event_id=event_payload["event_id"])
return True
except httpx.HTTPError as e:
logger.error("webhook_failed", error=str(e))
return False
class RecordingStatusQuerier:
# ... (previous init and methods) ...
def poll_recording(self, recording_id: str, tracker: RecordingStateTracker, sync: MediaEventSync) -> Optional[str]:
endpoint = f"/api/v2/media/recordings/{recording_id}"
start_time = time.time()
response = self._get_with_retry(endpoint)
response.raise_for_status()
data = response.json()
latency_ms = (time.time() - start_time) * 1000
self.metrics["total_checks"] += 1
self.metrics["total_latency_ms"] += latency_ms
try:
pipeline = RecordingValidationPipeline(**data)
except Exception as e:
logger.error("validation_failed", recording_id=recording_id, error=str(e))
return None
current_state = RecordingState(data["status"])
transitioned = tracker.check_transition(recording_id, current_state)
if transitioned:
self.metrics["successful_checks"] += 1
self.metrics["state_transitions"].append({
"recording_id": recording_id,
"new_state": current_state.value,
"timestamp": datetime.now(timezone.utc).isoformat()
})
download_url = pipeline.get_download_url()
if download_url:
sync.post_status_event(
recording_id=recording_id,
status=current_state.value,
transcription_status=pipeline.transcription_status,
download_url=download_url,
latency_ms=latency_ms
)
logger.info("recording_ready", recording_id=recording_id, download_url=download_url)
return download_url
time.sleep(self.directive.polling_interval_seconds)
return None

Common Errors & Debugging
Error: 429 Too Many Requests
- Cause: The polling loop exceeds the configured
rate_limit_requests_per_minuteor ignores theRetry-Afterheader returned by Genesys Cloud. - Fix: The
_enforce_rate_limitmethod tracks request timestamps and sleeps when the window fills. The_get_with_retrymethod explicitly parsesRetry-Afterand applies exponential backoff. Verify thatrate_limit_requests_per_minutematches your organization’s API tier. - Code Reference: See
_get_with_retryretry loop and_enforce_rate_limitsliding window logic.
Error: 401 Unauthorized or Token Expiration
- Cause: The bearer token expired mid-poll, or the client credentials lack
media:recordings:view. - Fix: The
GenesysAuthManagercaches tokens and subtracts 30 seconds from the expiry window to prevent edge-case failures. The polling loop catches401and forces a token refresh by settingself.auth._access_token = None. - Code Reference:
get_tokenexpiry buffer and401handling in_get_with_retry.
Error: Pydantic ValidationError on Audio Format or Duration
- Cause: Genesys Cloud returns a recording with
duration: 0.0or an unsupportedaudioFormatlikeflacin environments that only provisionwavormp3. - Fix: The
RecordingValidationPipelineenforces strict field validators. When validation fails, the loop logs the error and continues polling. Adjust thevalidate_formatallowlist if your tenant supports additional codecs. - Code Reference:
field_validatormethods inRecordingValidationPipeline.
Error: Missing Download Link in Links Object
- Cause: The recording status is
completebut thelinks.downloadobject is absent because media storage provisioning is delayed or the recording failed post-processing. - Fix: The
is_transcription_readymethod requires bothstatus == completeandtranscription_statusalignment before attempting extraction. The system waits for the next polling cycle until the link materializes. - Code Reference:
get_download_urlconditional check.
