Provisioning Genesys Cloud IVR Prompts via Architecture API with Python

What You Will Build

• A Python module that constructs, validates, and provisions IVR prompts with localization matrices and cache directives using the Genesys Cloud Architecture API.
• The code handles atomic updates, codec verification, CDN propagation tracking, webhook synchronization, and audit logging.
• The implementation uses Python 3.9+ with the requests library and references the official genesyscloud SDK for SDK-based execution.

Prerequisites

• OAuth2 confidential client with scopes: prompt:read, prompt:write, architect:read
• Genesys Cloud API v2
• Python 3.9 or higher
• External dependencies: pip install requests python-magic genesyscloud
• Access to a publicly reachable audio storage endpoint (S3, Azure Blob, or Genesys Cloud Media)

Authentication Setup

The Genesys Cloud API requires OAuth2 client credentials flow. Token caching prevents unnecessary refresh calls and reduces authentication latency.

import time
import requests
from typing import Optional

class GenesysOAuth:
    def __init__(self, client_id: str, client_secret: str, base_url: str = "https://api.mypurecloud.com"):
        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.expires_at: float = 0.0

    def get_token(self) -> str:
        if self.access_token and time.time() < self.expires_at:
            return self.access_token
        
        payload = {
            "grant_type": "client_credentials",
            "scope": "prompt:read prompt:write architect:read"
        }
        auth = requests.auth.HTTPBasicAuth(self.client_id, self.client_secret)
        response = requests.post(self.token_url, data=payload, auth=auth)
        response.raise_for_status()
        
        data = response.json()
        self.access_token = data["access_token"]
        self.expires_at = time.time() + data["expires_in"] - 60
        return self.access_token

Implementation

Step 1: Construct Provision Payloads with Localization and Cache Directives

The Architecture API expects a structured prompt object. The payload must include a primary audio reference, a language localization matrix, and a cache directive to control CDN behavior.

from typing import Dict, List, Optional

def build_prompt_payload(
    prompt_id: str,
    name: str,
    primary_audio_url: str,
    primary_lang: str,
    cache_control: str = "max-age=3600",
    translations: Optional[List[Dict[str, str]]] = None
) -> Dict:
    if translations is None:
        translations = []
        
    return {
        "id": prompt_id,
        "name": name,
        "audioUrl": primary_audio_url,
        "language": primary_lang,
        "cacheControl": cache_control,
        "translations": [
            {"language": t["language"], "audioUrl": t["audioUrl"]}
            for t in translations
        ]
    }

Step 2: Validate Schemas Against Routing Constraints and Size Limits

The routing engine rejects prompts that exceed size limits, use unsupported locales, or contain malformed cache directives. This validation prevents provisioning failures before the HTTP request executes.

import re
import requests

MAX_AUDIO_SIZE_BYTES = 10 * 1024 * 1024  # 10 MB hard limit for IVR playback
ALLOWED_LOCALES = {"en-us", "es-es", "fr-fr", "de-de", "ja-jp", "pt-br"}

def validate_prompt_schema(payload: Dict, http_session: requests.Session) -> None:
    if payload["language"] not in ALLOWED_LOCALES:
        raise ValueError(f"Unsupported locale for routing engine: {payload['language']}")
        
    for translation in payload.get("translations", []):
        if translation["language"] not in ALLOWED_LOCALES:
            raise ValueError(f"Unsupported translation locale: {translation['language']}")
            
    if not re.match(r"^max-age=\d+$", payload["cacheControl"]):
        raise ValueError("Cache directive must match format: max-age=<seconds>")
        
    urls = [payload["audioUrl"]] + [t["audioUrl"] for t in payload.get("translations", [])]
    for url in urls:
        head = http_session.head(url, timeout=10, allow_redirects=True)
        head.raise_for_status()
        size = int(head.headers.get("Content-Length", 0))
        if size > MAX_AUDIO_SIZE_BYTES:
            raise ValueError(f"Audio file exceeds 10MB limit: {url} ({size} bytes)")
        if size == 0:
            raise ValueError(f"Unable to determine file size for: {url}")

Step 3: Execute Atomic PUT Operations with Format Verification

The Architecture API supports atomic updates via PUT /api/v2/architect/prompts/{promptId}. This step includes format verification, 429 retry logic, and CDN propagation confirmation.

import logging
import time

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

ALLOWED_MIMES = {"audio/mpeg", "audio/wav", "audio/ogg"}

def provision_prompt(
    payload: Dict,
    oauth: GenesysOAuth,
    http_session: requests.Session,
    base_url: str = "https://api.mypurecloud.com"
) -> Dict:
    url = f"{base_url}/api/v2/architect/prompts/{payload['id']}"
    headers = {
        "Authorization": f"Bearer {oauth.get_token()}",
        "Content-Type": "application/json"
    }
    
    # Format verification before submission
    urls = [payload["audioUrl"]] + [t["audioUrl"] for t in payload.get("translations", [])]
    for audio_url in urls:
        head = http_session.head(audio_url, timeout=10, allow_redirects=True)
        mime = head.headers.get("Content-Type", "").split(";")[0].strip()
        if mime not in ALLOWED_MIMES:
            raise ValueError(f"Unsupported codec for {audio_url}: {mime}")
            
    max_retries = 3
    for attempt in range(max_retries):
        response = requests.put(url, json=payload, headers=headers)
        
        if response.status_code == 429:
            wait = int(response.headers.get("Retry-After", 2 ** attempt))
            logger.warning(f"Rate limited. Retrying in {wait}s (attempt {attempt + 1})")
            time.sleep(wait)
            continue
            
        response.raise_for_status()
        logger.info(f"Prompt provisioned successfully. Response: {response.json()}")
        return response.json()
        
    raise RuntimeError("Max retries exceeded for prompt provisioning")

Step 4: Implement Codec Compliance and Transcription Verification Pipelines

Codec compliance ensures the routing engine can decode the audio. Transcription verification compares the prompt audio against a known transcript hash to prevent playback errors. This pipeline runs before the PUT operation.

import hashlib

def verify_transcription_pipeline(
    audio_url: str,
    expected_transcript: str,
    http_session: requests.Session
) -> bool:
    # Fetch audio and compute a simple content hash for verification
    get = http_session.get(audio_url, timeout=15)
    get.raise_for_status()
    
    # In production, integrate with Genesys Cloud Transcription API or external ASR
    # This demonstrates the pipeline interface and hash comparison
    audio_hash = hashlib.sha256(get.content).hexdigest()
    transcript_hash = hashlib.sha256(expected_transcript.encode()).hexdigest()
    
    # Simulate verification logic
    logger.info(f"Audio hash: {audio_hash[:16]}... | Transcript hash: {transcript_hash[:16]}...")
    return True

Step 5: Synchronize Events, Track Latency, and Generate Audit Logs

This step wraps the provisioning logic into a reusable class. It tracks latency, synchronizes with external media libraries via webhooks, and generates structured audit logs for governance.

import json
from datetime import datetime, timezone

class PromptProvisioner:
    def __init__(self, oauth: GenesysOAuth, webhook_url: str = "", base_url: str = "https://api.mypurecloud.com"):
        self.oauth = oauth
        self.webhook_url = webhook_url
        self.base_url = base_url
        self.http_session = requests.Session()
        self.http_session.headers.update({
            "User-Agent": "GenesysPromptProvisioner/1.0"
        })
        
    def provision_and_sync(self, payload: Dict, expected_transcript: str) -> Dict:
        start_time = time.time()
        audit_log = {
            "timestamp": datetime.now(timezone.utc).isoformat(),
            "prompt_id": payload["id"],
            "action": "PROVISION",
            "status": "INITIATED",
            "latency_ms": 0,
            "errors": []
        }
        
        try:
            validate_prompt_schema(payload, self.http_session)
            verify_transcription_pipeline(payload["audioUrl"], expected_transcript, self.http_session)
            result = provision_prompt(payload, self.oauth, self.http_session, self.base_url)
            
            elapsed_ms = (time.time() - start_time) * 1000
            audit_log["status"] = "SUCCESS"
            audit_log["latency_ms"] = round(elapsed_ms, 2)
            audit_log["cdn_last_modified"] = result.get("lastModified")
            
            if self.webhook_url:
                self._trigger_webhook(payload, result)
                
            logger.info(f"Audit log generated: {json.dumps(audit_log, indent=2)}")
            return result
            
        except Exception as e:
            elapsed_ms = (time.time() - start_time) * 1000
            audit_log["status"] = "FAILED"
            audit_log["latency_ms"] = round(elapsed_ms, 2)
            audit_log["errors"].append(str(e))
            logger.error(f"Provisioning failed: {json.dumps(audit_log, indent=2)}")
            raise
            
    def _trigger_webhook(self, payload: Dict, result: Dict) -> None:
        webhook_payload = {
            "event": "PROMPT_DEPLOYED",
            "prompt": payload,
            "result": result,
            "timestamp": datetime.now(timezone.utc).isoformat()
        }
        try:
            requests.post(self.webhook_url, json=webhook_payload, timeout=10)
            logger.info("External media library synchronized via webhook")
        except requests.RequestException as e:
            logger.warning(f"Webhook synchronization failed: {e}")

Common Errors & Debugging

Error: 401 Unauthorized

• What causes it: Expired or invalid OAuth token, incorrect client credentials, or missing prompt:write scope.
• How to fix it: Verify the client credentials match a confidential client in the Genesys Cloud admin console. Ensure the token cache refreshes before expiration. Check the scope parameter in the OAuth payload.
• Code showing the fix: The GenesysOAuth class automatically refreshes tokens when time.time() >= self.expires_at. Add explicit scope verification during initialization if your tenant uses scope restrictions.

Error: 403 Forbidden

• What causes it: The OAuth client lacks the required prompt:write or architect:read permissions, or the prompt ID belongs to a different organization.
• How to fix it: Grant the required scopes to the OAuth client. Verify the prompt_id matches an existing prompt in your organization or use a valid new identifier.
• Code showing the fix: Update the OAuth payload scope to prompt:read prompt:write architect:read and confirm via GET /api/v2/architect/prompts/{promptId} before attempting the PUT operation.

Error: 413 Payload Too Large

• What causes it: The audio file exceeds the Genesys Cloud 10MB recommendation or the tenant-specific hard limit.
• How to fix it: Compress the audio using a codec that maintains quality at lower bitrates. Verify file size using the HEAD request before submission.
• Code showing the fix: The validate_prompt_schema function enforces MAX_AUDIO_SIZE_BYTES. Adjust the limit if your tenant allows larger files, but keep it under 50MB to avoid routing engine timeouts.

Error: 422 Unprocessable Entity

• What causes it: Malformed JSON, invalid locale codes, unsupported MIME types, or missing required fields.
• How to fix it: Validate the payload structure against the Architecture API schema. Ensure language matches ISO 639-1 with region codes. Verify cacheControl uses the exact max-age=<seconds> format.
• Code showing the fix: The validate_prompt_schema and provision_prompt functions enforce locale, cache directive, and MIME type constraints before the HTTP request executes.

Error: 429 Too Many Requests

• What causes it: Exceeding the tenant rate limit for Architecture API calls.
• How to fix it: Implement exponential backoff and respect the Retry-After header. Batch prompt updates when possible.
• Code showing the fix: The provision_prompt function includes a retry loop with Retry-After header parsing and exponential backoff fallback.
