Managing Genesys Cloud IVR Menu Definitions via API with Python

What You Will Build

• A Python module that constructs, validates, publishes, and simulates Genesys Cloud Flow-based IVR menus using real DTMF routing logic and prompt audio references.
• Integration with the Routing API to dynamically adjust menu behavior based on real-time queue occupancy, combined with analytics tracking for abandonment rates and compliance audit logging.
• Python 3.9+ implementation using the requests library with production-grade error handling, optimistic concurrency control, and retry logic.

Prerequisites

• OAuth2 Client Credentials flow configured in Genesys Cloud Admin Console
• Required scopes: flow:write flow:read routing:queue:read analytics:conversation:read audit:read routing:phrase:write
• Python 3.9 or higher
• External dependencies: requests>=2.31.0, pydantic>=2.5.0 (for payload validation), tenacity>=8.2.0 (for retry logic)
• Install dependencies: pip install requests pydantic tenacity

Authentication Setup

Genesys Cloud uses OAuth2 Client Credentials for server-to-server API access. Token caching prevents unnecessary authentication calls and reduces 401 failures.

import requests
import time
import json
from typing import Optional

class GenesysAuth:
    def __init__(self, client_id: str, client_secret: str, environment: str = "api.mypurecloud.com"):
        self.client_id = client_id
        self.client_secret = client_secret
        self.env = environment
        self.token_url = f"https://{environment}/oauth/token"
        self._access_token: Optional[str] = None
        self._token_expiry: float = 0.0

    def _get_token(self) -> dict:
        payload = {
            "grant_type": "client_credentials",
            "client_id": self.client_id,
            "client_secret": self.client_secret,
            "scope": "flow:write flow:read routing:queue:read analytics:conversation:read audit:read routing:phrase:write"
        }
        response = requests.post(self.token_url, data=payload)
        response.raise_for_status()
        return response.json()

    def get_headers(self) -> dict:
        if time.time() >= self._token_expiry - 60:
            token_data = self._get_token()
            self._access_token = token_data["access_token"]
            self._token_expiry = time.time() + token_data["expires_in"]
        return {
            "Authorization": f"Bearer {self._access_token}",
            "Content-Type": "application/json",
            "Accept": "application/json"
        }

Implementation

Step 1: Construct and Validate Menu Node Payloads

Genesys Cloud IVR menus are defined as Flow JSON documents. The payload must include DTMF handlers, prompt references, timeout configurations, and routing targets. System limits restrict menu depth to five levels and timeouts to 1-60 seconds.

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

class DtmfNode(BaseModel):
    key: str
    target_flow_id: str
    prompt_id: Optional[str] = None

class MenuNode(BaseModel):
    node_id: str
    type: str = "dtmf"
    prompt_id: str
    timeout_seconds: int
    timeout_target: str
    dtmf_handlers: List[DtmfNode]
    children: List["MenuNode"] = []

    @field_validator("timeout_seconds")
    @classmethod
    def validate_timeout(cls, v: int) -> int:
        if not (1 <= v <= 60):
            raise ValueError("Timeout must be between 1 and 60 seconds.")
        return v

class IvRMenuPayload(BaseModel):
    menu_id: str
    name: str
    root_node: MenuNode
    max_depth: int = 5

    @field_validator("max_depth")
    @classmethod
    def validate_depth(cls, v: int) -> int:
        if not (1 <= v <= 5):
            raise ValueError("Menu depth must be between 1 and 5.")
        return v

    def _calculate_depth(self, node: MenuNode, current_depth: int = 1) -> int:
        if current_depth > self.max_depth:
            raise ValueError(f"Menu depth exceeds maximum of {self.max_depth}.")
        max_child_depth = current_depth
        for child in node.children:
            max_child_depth = max(max_child_depth, self._calculate_depth(child, current_depth + 1))
        return max_child_depth

    def to_flow_json(self) -> Dict[str, Any]:
        self._calculate_depth(self.root_node)
        return {
            "name": self.name,
            "type": "conversation",
            "settings": {
                "description": f"IVR Menu {self.menu_id}",
                "enabled": True,
                "version": 1
            },
            "steps": [
                {
                    "id": "start",
                    "type": "start",
                    "nextStep": self._serialize_node(self.root_node)
                }
            ]
        }

    def _serialize_node(self, node: MenuNode) -> Dict[str, Any]:
        return {
            "id": node.node_id,
            "type": "dtmf",
            "promptId": node.prompt_id,
            "timeoutSeconds": node.timeout_seconds,
            "timeoutTarget": node.timeout_target,
            "dtmfHandlers": [
                {"key": h.key, "targetFlowId": h.target_flow_id, "promptId": h.prompt_id}
                for h in node.dtmf_handlers
            ],
            "nextSteps": [self._serialize_node(c) for c in node.children]
        }

Step 2: Handle Asynchronous Publication and Version Control

Genesys Cloud uses optimistic concurrency control via the _version field. Publication requires fetching the current version, incrementing it, and handling 409 conflicts with exponential backoff.

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

class FlowPublisher:
    def __init__(self, auth: GenesysAuth, environment: str):
        self.auth = auth
        self.base_url = f"https://{environment}/api/v2"

    def _get_flow_version(self, flow_id: str) -> int:
        url = f"{self.base_url}/flows/{flow_id}"
        headers = self.auth.get_headers()
        response = requests.get(url, headers=headers)
        response.raise_for_status()
        return response.json().get("_version", 0)

    @retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, min=2, max=10),
           retry=retry_if_exception_type(requests.exceptions.HTTPError))
    def publish_menu(self, flow_id: str, payload: Dict[str, Any]) -> dict:
        url = f"{self.base_url}/flows/{flow_id}"
        headers = self.auth.get_headers()
        headers["Accept"] = "application/json"
        
        current_version = self._get_flow_version(flow_id)
        payload["settings"]["version"] = current_version + 1
        
        response = requests.patch(url, json=payload, headers=headers)
        
        if response.status_code == 409:
            raise requests.exceptions.HTTPError("Version conflict detected. Retrying with fresh version.")
        response.raise_for_status()
        return response.json()

Step 3: Implement Dynamic Updates via Routing API

Real-time queue occupancy data drives dynamic timeout adjustments and routing target selection. High occupancy triggers extended timeouts and fallback routing.

class RoutingAdaptor:
    def __init__(self, auth: GenesysAuth, environment: str):
        self.auth = auth
        self.base_url = f"https://{environment}/api/v2"

    def get_queue_occupancy(self, queue_id: str) -> dict:
        url = f"{self.base_url}/routing/queues/{queue_id}/statistics"
        headers = self.auth.get_headers()
        response = requests.get(url, headers=headers)
        response.raise_for_status()
        return response.json()

    def adjust_menu_for_occupancy(self, menu_payload: Dict[str, Any], queue_id: str) -> Dict[str, Any]:
        stats = self.get_queue_occupancy(queue_id)
        agents_available = stats.get("agents", {}).get("available", 0)
        wait_seconds = stats.get("queue", {}).get("waitSeconds", {}).get("current", 0)

        if wait_seconds > 120 or agents_available == 0:
            menu_payload["settings"]["dynamicTimeoutMultiplier"] = 2.0
            menu_payload["settings"]["fallbackEnabled"] = True
        else:
            menu_payload["settings"]["dynamicTimeoutMultiplier"] = 1.0
            menu_payload["settings"]["fallbackEnabled"] = False

        return menu_payload

Step 4: Synchronize Translations and Track Abandonment Analytics

Menu prompts require localization. The Routing API handles phrase batch updates. Abandonment analytics use the Conversation Analytics API to measure UX friction.

class TranslationAndAnalyticsManager:
    def __init__(self, auth: GenesysAuth, environment: str):
        self.auth = auth
        self.base_url = f"https://{environment}/api/v2"

    def batch_update_phrases(self, phrase_updates: List[Dict[str, Any]]) -> dict:
        url = f"{self.base_url}/routing/phrases/bulk"
        headers = self.auth.get_headers()
        payload = {"phrases": phrase_updates}
        response = requests.post(url, json=payload, headers=headers)
        response.raise_for_status()
        return response.json()

    def get_abandonment_rate(self, flow_id: str, time_range: str = "last7d") -> dict:
        url = f"{self.base_url}/analytics/conversations/summary/query"
        headers = self.auth.get_headers()
        query = {
            "timeRange": {"type": "relative", "duration": time_range},
            "filter": {
                "type": "and",
                "filters": [
                    {"type": "eq", "field": "flow.id", "value": flow_id},
                    {"type": "eq", "field": "conversation.outcome", "value": "abandoned"}
                ]
            },
            "groupBy": ["flow.id"],
            "metrics": ["conversation.count"]
        }
        response = requests.post(url, json=query, headers=headers)
        response.raise_for_status()
        return response.json()

Step 5: Generate Audit Logs and Expose Menu Simulator

Compliance requires tracking every menu modification. The simulator provides a local test environment for DTMF routing validation before deployment.

class AuditAndSimulator:
    def __init__(self, auth: GenesysAuth, environment: str):
        self.auth = auth
        self.base_url = f"https://{environment}/api/v2"

    def get_audit_logs(self, flow_id: str, limit: int = 100) -> List[dict]:
        url = f"{self.base_url}/auditlogs"
        headers = self.auth.get_headers()
        params = {
            "entityType": "flow",
            "entityId": flow_id,
            "limit": limit,
            "page": 1
        }
        all_logs = []
        while True:
            response = requests.get(url, headers=headers, params=params)
            response.raise_for_status()
            data = response.json()
            all_logs.extend(data.get("entities", []))
            if len(data.get("entities", [])) < limit:
                break
            params["page"] += 1
        return all_logs

    def simulate_dtmf_flow(self, flow_json: Dict[str, Any], dtmf_sequence: List[str]) -> List[str]:
        steps = flow_json.get("steps", [])
        if not steps:
            return ["Empty flow definition"]
        
        current_step_id = steps[0].get("nextStep")
        visited_nodes = []
        
        for dtmf in dtmf_sequence:
            node = self._find_node_by_id(flow_json, current_step_id)
            if not node:
                visited_nodes.append(f"Node {current_step_id} not found")
                break
            visited_nodes.append(f"Entered {node['id']}")
            
            handler = next((h for h in node.get("dtmfHandlers", []) if h["key"] == dtmf), None)
            if handler:
                current_step_id = handler.get("targetFlowId") or node.get("nextSteps", [{}])[0].get("id")
            else:
                current_step_id = node.get("timeoutTarget")
                visited_nodes.append(f"Timeout triggered on {node['id']}")
        
        return visited_nodes

    def _find_node_by_id(self, flow_json: Dict[str, Any], node_id: str) -> Optional[Dict[str, Any]]:
        steps = flow_json.get("steps", [])
        for step in steps:
            if step.get("id") == node_id:
                return step
            if step.get("nextStep") == node_id:
                return self._search_nested(step, node_id)
        return None

    def _search_nested(self, parent: Dict[str, Any], target_id: str) -> Optional[Dict[str, Any]]:
        if parent.get("id") == target_id:
            return parent
        for child in parent.get("nextSteps", []):
            result = self._search_nested(child, target_id)
            if result:
                return result
        return None

Common Errors & Debugging

Error: 401 Unauthorized

• What causes it: Expired access token or missing OAuth scopes in the client credentials grant.
• How to fix it: Verify the client_secret matches the Genesys Cloud application settings. Ensure the token cache refreshes before expiry. The GenesysAuth class handles automatic refresh 60 seconds before expiration.
• Code showing the fix: The _get_token method in GenesysAuth fetches a fresh token when the expiry threshold is crossed. Always call auth.get_headers() before API requests.

Error: 409 Conflict

• What causes it: Another process modified the Flow definition between your version fetch and patch request.
• How to fix it: Implement optimistic concurrency control. Fetch the latest _version, increment it, and retry. The publish_menu method uses tenacity to retry up to three times with exponential backoff.
• Code showing the fix: The @retry decorator on publish_menu catches 409 responses, triggers a fresh version fetch, and resubmits the payload.

Error: 429 Too Many Requests

• What causes it: Exceeding Genesys Cloud rate limits (typically 10-20 requests per second per client).
• How to fix it: Implement exponential backoff with jitter. The tenacity retry configuration handles 429s automatically. Add Retry-After header parsing for precision.
• Code showing the fix: The retry_if_exception_type(requests.exceptions.HTTPError) combined with wait_exponential ensures compliant retry behavior.

Error: Payload Validation Failure

• What causes it: Menu depth exceeds five levels or timeout values fall outside 1-60 seconds.
• How to fix it: The pydantic validators enforce constraints before API submission. Adjust max_depth or timeout_seconds in the MenuNode definition.
• Code showing the fix: The validate_timeout and validate_depth methods raise clear ValueError exceptions with actionable messages.
