Purging Genesys Cloud Interaction Archives via REST API with Python

What You Will Build

• A Python module that constructs and executes asynchronous purge jobs for conversation archives using interaction ID references and permanent deletion directives.
• The code uses the Genesys Cloud POST /api/v2/analytics/conversations/purge and job tracking endpoints.
• The tutorial covers Python 3.10+ with httpx, pydantic, and standard library logging.

Prerequisites

• OAuth client credentials (Client ID and Client Secret) with the required scope analytics:conversation:delete.
• Genesys Cloud REST API v2.
• Python 3.10 or later.
• External dependencies: httpx, pydantic, python-dotenv.

Authentication Setup

Genesys Cloud uses OAuth 2.0 client credentials grant for server-to-server API access. You must cache the access token and refresh it before expiration to avoid unnecessary token requests and 401 errors.

import httpx
import time
from typing import Optional
from dataclasses import dataclass
import logging

logger = logging.getLogger(__name__)

@dataclass
class OAuthToken:
    access_token: str
    expires_in: int
    obtained_at: float

class GenesysAuth:
    def __init__(self, client_id: str, client_secret: str, base_url: str):
        self.client_id = client_id
        self.client_secret = client_secret
        self.base_url = base_url.rstrip("/")
        self.token: Optional[OAuthToken] = None
        self.http_client = httpx.Client(timeout=30.0)

    def _fetch_token(self) -> OAuthToken:
        response = self.http_client.post(
            f"{self.base_url}/oauth/token",
            data={"grant_type": "client_credentials"},
            auth=(self.client_id, self.client_secret),
            headers={"Content-Type": "application/x-www-form-urlencoded"}
        )
        response.raise_for_status()
        payload = response.json()
        return OAuthToken(
            access_token=payload["access_token"],
            expires_in=payload["expires_in"],
            obtained_at=time.time()
        )

    def get_access_token(self) -> str:
        if self.token and (time.time() - self.token.obtained_at) < self.token.expires_in - 300:
            return self.token.access_token
        logger.info("Refreshing OAuth token.")
        self.token = self._fetch_token()
        return self.token.access_token

Implementation

Step 1: Retention Matrix Validation and Legal Hold Filtering

Before submitting purge requests, you must verify that conversations meet retention policy constraints and are not protected by legal holds. The Genesys Cloud API rejects purge requests for protected records with a 409 Conflict. You can pre-filter records by querying conversation details and checking metadata against a retention matrix.

from pydantic import BaseModel, field_validator
from typing import List, Dict, Any
import httpx

class PurgeValidator:
    def __init__(self, auth: GenesysAuth, retention_days: int = 365):
        self.auth = auth
        self.retention_days = retention_days
        self.http_client = httpx.Client(timeout=30.0)

    def fetch_conversation_metadata(self, conversation_ids: List[str]) -> Dict[str, Any]:
        # Query analytics details for soft-delete status and wrap-up codes
        body = {
            "query": f'conversationId IN ({",".join(f"\"{cid}\"" for cid in conversation_ids)})',
            "view": "default"
        }
        headers = {
            "Authorization": f"Bearer {self.auth.get_access_token()}",
            "Content-Type": "application/json"
        }
        response = self.http_client.post(
            f"{self.auth.base_url}/api/v2/analytics/conversations/details/query",
            json=body,
            headers=headers
        )
        response.raise_for_status()
        return response.json()

    def validate_purge_eligibility(self, conversation_ids: List[str]) -> List[str]:
        metadata = self.fetch_conversation_metadata(conversation_ids)
        eligible_ids = []
        
        for record in metadata.get("data", []):
            cid = record["conversationId"]
            status = record.get("conversationStatus", "")
            
            # Soft-delete verification: skip if already marked for deletion
            if status in ("deleted", "purged"):
                logger.debug(f"Skipping {cid}: already soft-deleted.")
                continue
                
            # Legal hold simulation: Genesys returns specific flags or rejects at purge time
            # We filter based on known hold indicators in custom attributes or status
            if record.get("customAttributes", {}).get("legal_hold", False):
                logger.warning(f"Skipping {cid}: protected by legal hold.")
                continue
                
            eligible_ids.append(cid)
            
        logger.info(f"Validated {len(eligible_ids)}/{len(conversation_ids)} eligible for purge.")
        return eligible_ids

Step 2: Payload Construction and Concurrent Purge Execution

The purge endpoint accepts a batch of conversation IDs. Genesys Cloud enforces a maximum concurrent purge job limit and a batch size limit. You must construct the payload with explicit permanent deletion directives and implement retry logic for 429 rate limits.

from pydantic import BaseModel, field_validator
import time
import random

class PurgeRequest(BaseModel):
    conversationIds: List[str]
    permanentDelete: bool = True

    @field_validator("conversationIds")
    @classmethod
    def validate_batch_size(cls, v: List[str]) -> List[str]:
        if len(v) > 1000:
            raise ValueError("Genesys Cloud purge API enforces a maximum batch size of 1000 IDs.")
        return v

class GenesysPurgeExecutor:
    def __init__(self, auth: GenesysAuth, max_retries: int = 3):
        self.auth = auth
        self.http_client = httpx.Client(timeout=60.0)
        self.max_retries = max_retries

    def _execute_with_retry(self, url: str, payload: PurgeRequest) -> Dict[str, Any]:
        headers = {
            "Authorization": f"Bearer {self.auth.get_access_token()}",
            "Content-Type": "application/json"
        }
        
        for attempt in range(self.max_retries):
            response = self.http_client.post(url, json=payload.model_dump(), headers=headers)
            
            if response.status_code == 429:
                retry_after = int(response.headers.get("Retry-After", 2 ** attempt))
                logger.warning(f"Rate limited (429). Retrying in {retry_after}s.")
                time.sleep(retry_after)
                continue
                
            response.raise_for_status()
            return response.json()
            
        raise httpx.HTTPStatusError("Max retries exceeded for 429", request=None, response=response)

    def submit_purge_job(self, eligible_ids: List[str]) -> str:
        # Chunk IDs to respect concurrent job limits and batch constraints
        chunk_size = 500
        job_ids = []
        
        for i in range(0, len(eligible_ids), chunk_size):
            chunk = eligible_ids[i:i + chunk_size]
            payload = PurgeRequest(conversationIds=chunk, permanentDelete=True)
            
            # Atomic DELETE operation via POST trigger
            result = self._execute_with_retry(
                f"{self.auth.base_url}/api/v2/analytics/conversations/purge",
                payload
            )
            
            job_id = result.get("jobId")
            job_ids.append(job_id)
            logger.info(f"Submitted purge job {job_id} for {len(chunk)} conversations.")
            
        return job_ids[0] if len(job_ids) == 1 else job_ids

Step 3: Async Job Tracking and Index Cleanup Verification

Purge operations run asynchronously. You must poll the job status endpoint until completion. The response includes format verification results and automatic index cleanup triggers. You will also track latency and emit webhook callbacks for external retention platforms.

import json
from datetime import datetime, timezone

class PurgeTracker:
    def __init__(self, auth: GenesysAuth, webhook_url: Optional[str] = None):
        self.auth = auth
        self.http_client = httpx.Client(timeout=30.0)
        self.webhook_url = webhook_url

    def poll_job_status(self, job_id: str) -> Dict[str, Any]:
        headers = {"Authorization": f"Bearer {self.auth.get_access_token()}"}
        start_time = time.time()
        
        while True:
            response = self.http_client.get(
                f"{self.auth.base_url}/api/v2/analytics/conversations/purge/{job_id}",
                headers=headers
            )
            response.raise_for_status()
            status_data = response.json()
            
            state = status_data.get("state", "").lower()
            
            if state in ("completed", "failed"):
                latency = time.time() - start_time
                logger.info(f"Job {job_id} finished. State: {state}. Latency: {latency:.2f}s")
                self._emit_webhook(job_id, status_data, latency)
                return status_data
                
            logger.debug(f"Job {job_id} pending. State: {state}. Waiting 5s.")
            time.sleep(5)

    def _emit_webhook(self, job_id: str, status: Dict[str, Any], latency: float):
        if not self.webhook_url:
            return
            
        payload = {
            "event": "purge_job_completed",
            "jobId": job_id,
            "state": status.get("state"),
            "recordsProcessed": status.get("recordsProcessed", 0),
            "latencySeconds": round(latency, 2),
            "timestamp": datetime.now(timezone.utc).isoformat()
        }
        
        try:
            self.http_client.post(self.webhook_url, json=payload)
            logger.info(f"Webhook dispatched for job {job_id}.")
        except httpx.HTTPError as e:
            logger.error(f"Webhook delivery failed for {job_id}: {e}")

Common Errors and Debugging

Error: 403 Forbidden

• Cause: The OAuth token lacks the analytics:conversation:delete scope, or the client credentials are misconfigured.
• Fix: Verify the client ID and secret. Regenerate the token and inspect the scope claim in the JWT payload. Ensure the application has been granted the required permission in the Genesys Cloud admin console.
• Code Fix: The get_access_token method automatically refreshes expired tokens. If 403 persists, log the token scopes and update the client configuration.

Error: 409 Conflict

• Cause: The purge request targets conversations protected by legal holds, active litigation flags, or retention policies that have not yet expired.
• Fix: Review the validate_purge_eligibility output. The API rejects the entire batch if any ID violates constraints. Filter protected records before submission. Check the conversationStatus and custom attributes for hold indicators.
• Code Fix: The validator skips records with legal_hold flags and soft-deleted statuses. Adjust the retention matrix threshold if premature purging is attempted.

Error: 429 Too Many Requests

• Cause: Exceeding the maximum concurrent purge job limit or hitting global rate limits on the analytics service.
• Fix: Reduce batch chunk size. Implement exponential backoff. The _execute_with_retry method handles automatic retries with Retry-After header compliance.
• Code Fix: Ensure chunk_size does not exceed 500. Monitor the Retry-After header value and adjust sleep intervals accordingly.

Error: 504 Gateway Timeout

• Cause: The async purge job is still processing large volumes of data. The polling interval may be too aggressive or the job exceeds default timeout windows.
• Fix: Increase polling intervals. The tracker uses a 5-second sleep cycle. For jobs processing tens of thousands of records, expect completion times of several minutes. Monitor the state field for inProgress.
• Code Fix: The poll_job_status loop continues until completed or failed. Add a maximum timeout guard if your infrastructure requires hard cutoffs.
