Classify Real-Time Agent Assist Intent Matches with Python SDK

Classify Real-Time Agent Assist Intent Matches with Python SDK

What You Will Build

A production-grade Python module that constructs, validates, and executes atomic classification requests against the Genesys Cloud Agent Assist Knowledge Base Search API. The code filters results by confidence thresholds and domain restrictions, tracks latency and success rates, generates structured audit logs, and synchronizes classification events to external QA webhooks. This tutorial uses the official genesyscloud Python SDK and httpx for webhook delivery.

Prerequisites

  • OAuth Client Type: Service Account or User Impersonation
  • Required Scopes: agentassist:knowledgebase:read, agentassist:search:read
  • SDK Version: genesyscloud>=1.2.0
  • Runtime: Python 3.9 or higher
  • External Dependencies: pip install genesyscloud httpx pydantic typing_extensions

Authentication Setup

Genesys Cloud requires OAuth 2.0 client credentials or user password grant. The Python SDK handles token acquisition and refresh automatically when initialized with PlatformClient. You must cache the client instance to avoid redundant authentication calls.

import os
from genesyscloud.platform.client import PlatformClient
from genesyscloud.platform.auth import OAuthClientCredentialsConfig

def initialize_genesys_client() -> PlatformClient:
    """Initialize and return a cached Genesys Cloud PlatformClient."""
    org_id = os.getenv("GENESYS_ORG_ID")
    client_id = os.getenv("GENESYS_CLIENT_ID")
    client_secret = os.getenv("GENESYS_CLIENT_SECRET")
    
    if not all([org_id, client_id, client_secret]):
        raise ValueError("GENESYS_ORG_ID, GENESYS_CLIENT_ID, and GENESYS_CLIENT_SECRET must be set.")
        
    oauth_config = OAuthClientCredentialsConfig(
        client_id=client_id,
        client_secret=client_secret,
        org_id=org_id,
        scopes=["agentassist:knowledgebase:read", "agentassist:search:read"]
    )
    
    client = PlatformClient(config=oauth_config)
    client.login()
    return client

The SDK stores the access token and automatically refreshes it before expiration. You will use this PlatformClient instance to instantiate the AgentAssistApi module in subsequent steps.

Implementation

Step 1: SDK Initialization & Knowledge Base Fetch Trigger

Before executing classification, you must verify the target Knowledge Base exists and is active. This automatic fetch trigger prevents routing requests to deprecated or misconfigured KBs. The SDK method get_knowledge_base performs a GET request to /api/v2/agentassist/knowledgebases/{knowledgeBaseId}.

from genesyscloud.api import AgentAssistApi
from genesyscloud.models import KnowledgeBase

def fetch_knowledge_base(client: PlatformClient, kb_id: str) -> KnowledgeBase:
    """Fetch KB metadata to verify routing configuration before classification."""
    agent_assist_api = AgentAssistApi(client)
    
    try:
        response = agent_assist_api.get_knowledge_base(knowledge_base_id=kb_id)
        if response.status_code not in (200, 201):
            raise RuntimeError(f"KB fetch failed with status {response.status_code}: {response.body}")
        return response.body
    except Exception as e:
        raise ConnectionError(f"Knowledge Base fetch trigger failed: {str(e)}")

HTTP Equivalent:

GET /api/v2/agentassist/knowledgebases/{knowledgeBaseId} HTTP/1.1
Host: api.mypurecloud.com
Authorization: Bearer <access_token>
Accept: application/json

HTTP/1.1 200 OK
Content-Type: application/json
{
  "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "name": "Billing & Support KB",
  "description": "Primary agent assist knowledge base",
  "status": "published",
  "language": "en-US",
  "vectorEmbeddingEnabled": true
}

This step confirms vectorEmbeddingEnabled is true, which is required for synonym expansion and vector routing logic downstream.

Step 2: Payload Construction & Schema Validation

The classification payload requires an intent reference, transcript matrix (input text context), and score directive (confidence threshold). You will use Pydantic to enforce schema constraints before sending data to the API. This prevents classification failures caused by malformed requests or out-of-bounds thresholds.

from pydantic import BaseModel, Field, validator
from typing import List, Optional

class SearchOptions(BaseModel):
    synonymExpansion: bool = Field(default=True, description="Enable synonym expansion logic")
    vectorRouting: bool = Field(default=True, description="Enable vector embedding routing")
    domainRestriction: Optional[str] = Field(default=None, description="Restrict search to specific domain")

class ClassifyPayload(BaseModel):
    intent_reference: str = Field(..., min_length=3, max_length=100)
    transcript_matrix: str = Field(..., min_length=1, max_length=2000)
    score_directive: float = Field(..., ge=0.0, le=1.0)
    language: str = Field(default="en-US")
    limit: int = Field(default=5, ge=1, le=20)
    search_options: SearchOptions = Field(default_factory=SearchOptions)

    @validator("score_directive")
    def validate_confidence_threshold(cls, v):
        if v < 0.05:
            raise ValueError("Score directive must be at least 0.05 to prevent noise classification.")
        return v

The ClassifyPayload model enforces AI constraints. The score_directive acts as your maximum confidence threshold filter. The transcript_matrix holds the real-time conversation snippet. The search_options dictionary maps directly to the Genesys Cloud API body parameters.

Step 3: Atomic POST Execution & Confidence Threshold Enforcement

You will execute the classification via an atomic POST operation to /api/v2/agentassist/knowledgebases/{knowledgeBaseId}/search. The SDK method search_knowledge_base handles serialization, retry logic for 429 responses, and deserialization. You must wrap the call in a retry decorator to handle rate limits gracefully.

import time
import httpx
from genesyscloud.models import SearchRequest, SearchOptions as SDKSearchOptions
from functools import wraps

def retry_on_rate_limit(max_retries: int = 3, base_delay: float = 1.0):
    def decorator(func):
        @wraps(func)
        def wrapper(*args, **kwargs):
            for attempt in range(max_retries):
                try:
                    return func(*args, **kwargs)
                except Exception as e:
                    error_msg = str(e).lower()
                    if "429" in error_msg or "rate limit" in error_msg:
                        delay = base_delay * (2 ** attempt)
                        time.sleep(delay)
                        continue
                    raise
            raise RuntimeError("Max retries exceeded due to rate limiting.")
        return wrapper
    return decorator

@retry_on_rate_limit(max_retries=3)
def execute_classification(client: PlatformClient, kb_id: str, payload: ClassifyPayload):
    """Execute atomic POST classification against Agent Assist API."""
    agent_assist_api = AgentAssistApi(client)
    
    # Map Pydantic model to SDK models
    sdk_search_options = SDKSearchOptions(
        synonym_expansion=payload.search_options.synonymExpansion,
        vector_routing=payload.search_options.vectorRouting,
        domain_restriction=payload.search_options.domainRestriction
    )
    
    search_request = SearchRequest(
        text=payload.transcript_matrix,
        language=payload.language,
        limit=payload.limit,
        search_options=sdk_search_options
    )
    
    response = agent_assist_api.search_knowledge_base(
        knowledge_base_id=kb_id,
        body=search_request
    )
    
    if response.status_code != 200:
        raise RuntimeError(f"Classification POST failed: {response.status_code} {response.body}")
        
    return response.body

HTTP Request/Response Cycle:

POST /api/v2/agentassist/knowledgebases/a1b2c3d4-e5f6-7890-abcd-ef1234567890/search HTTP/1.1
Host: api.mypurecloud.com
Authorization: Bearer <access_token>
Content-Type: application/json
Accept: application/json

{
  "text": "I want to dispute a charge on my statement",
  "language": "en-US",
  "limit": 5,
  "searchOptions": {
    "synonymExpansion": true,
    "vectorRouting": true,
    "domainRestriction": "billing"
  }
}

HTTP/1.1 200 OK
Content-Type: application/json
{
  "results": [
    {
      "id": "article-001",
      "title": "How to Dispute a Billing Charge",
      "score": 0.94,
      "domain": "billing",
      "summary": "Step-by-step guide to filing a dispute..."
    },
    {
      "id": "article-002",
      "title": "Understanding Statement Cycles",
      "score": 0.78,
      "domain": "billing",
      "summary": "Overview of monthly billing periods..."
    }
  ],
  "totalResults": 2
}

The SDK handles the atomic POST. You must enforce the score_directive threshold immediately after receiving the response to prevent low-confidence results from reaching the agent.

Step 4: Ambiguity Filtering & Domain Restriction Pipeline

Raw API results may contain ambiguous matches or cross-domain suggestions. You will implement a validation pipeline that filters results by the score_directive threshold and verifies domain alignment. This ensures precise agent recommendations during Genesys Cloud scaling events when traffic spikes increase noise.

from typing import Dict, Any

def filter_classification_results(
    raw_results: List[Dict[str, Any]], 
    payload: ClassifyPayload
) -> List[Dict[str, Any]]:
    """Apply ambiguity filtering and domain restriction verification."""
    filtered = []
    
    for item in raw_results:
        score = item.get("score", 0.0)
        domain = item.get("domain", "")
        
        # Enforce maximum confidence threshold limit
        if score < payload.score_directive:
            continue
            
        # Domain restriction verification pipeline
        if payload.search_options.domainRestriction:
            if domain.lower() != payload.search_options.domainRestriction.lower():
                continue
                
        # Ambiguity filtering: discard results with near-identical scores
        if filtered:
            top_score = filtered[-1].get("score", 0.0)
            if abs(score - top_score) < 0.02:
                continue
                
        filtered.append(item)
        
    return filtered

This pipeline runs after the SDK deserializes the response. It removes results below the threshold, blocks cross-domain leakage, and collapses ambiguous clusters where multiple articles return nearly identical confidence scores. Agents only receive high-signal recommendations.

Step 5: Webhook Synchronization, Latency Tracking & Audit Logging

You must synchronize classification events with external QA systems, track latency, and generate audit logs for governance. The following function handles webhook delivery, metrics calculation, and structured logging. It uses httpx for reliable HTTP POST delivery to your QA endpoint.

import json
import logging
from datetime import datetime, timezone

logger = logging.getLogger("agentassist.classifier")

def sync_and_log(
    payload: ClassifyPayload,
    filtered_results: List[Dict[str, Any]],
    latency_ms: float,
    qa_webhook_url: str
) -> Dict[str, Any]:
    """Synchronize with external QA, track latency, and generate audit logs."""
    timestamp = datetime.now(timezone.utc).isoformat()
    
    audit_log = {
        "timestamp": timestamp,
        "intent_reference": payload.intent_reference,
        "transcript_length": len(payload.transcript_matrix),
        "score_directive": payload.score_directive,
        "results_count": len(filtered_results),
        "latency_ms": latency_ms,
        "success_rate": 1.0 if filtered_results else 0.0,
        "top_recommendation": filtered_results[0] if filtered_results else None
    }
    
    # Generate audit log for assist governance
    logger.info(json.dumps(audit_log))
    
    # Synchronize with external QA system via webhook
    if qa_webhook_url:
        try:
            with httpx.Client(timeout=5.0) as client:
                resp = client.post(
                    qa_webhook_url,
                    json={"event": "intent_classified", "data": audit_log},
                    headers={"Content-Type": "application/json"}
                )
                if resp.status_code >= 400:
                    logger.warning(f"QA webhook sync failed: {resp.status_code} {resp.text}")
        except Exception as e:
            logger.error(f"QA webhook delivery error: {str(e)}")
            
    return audit_log

The latency_ms parameter is calculated by measuring the time delta between payload construction and API response receipt. The success_rate metric tracks how often classifications return valid results above the threshold. The webhook payload aligns with standard QA alignment schemas.

Common Errors & Debugging

Error: 401 Unauthorized or 403 Forbidden

Cause: The OAuth client lacks the agentassist:knowledgebase:read or agentassist:search:read scopes, or the token has expired.
Fix: Verify the scopes in your OAuthClientCredentialsConfig. Ensure the service account has the Agent Assist Administrator or Agent Assist Viewer role assigned in the Genesys Cloud admin console. The SDK automatically refreshes tokens, but stale cached sessions may require a fresh client.login() call.

Error: 429 Too Many Requests

Cause: Exceeding the Genesys Cloud rate limit for the /search endpoint (typically 10-20 requests per second per org).
Fix: The retry_on_rate_limit decorator implements exponential backoff. For sustained high-volume classification, implement a token bucket rate limiter before invoking execute_classification. Reduce the limit parameter if batching multiple transcripts per call.

Error: Pydantic ValidationError on score_directive

Cause: The confidence threshold falls below the enforced minimum of 0.05 or exceeds 1.0.
Fix: Adjust the score_directive in your payload. Values below 0.05 typically return noise. Values above 0.95 may return zero results during scaling events. Maintain a dynamic threshold based on historical success rates.

Error: Domain Restriction Mismatch Returns Empty List

Cause: The KB articles lack the domain metadata tag, or the tag casing differs from your domainRestriction parameter.
Fix: Verify article metadata in the Genesys Cloud Admin Console under Agent Assist > Knowledge Base > Articles. Normalize casing in the filtering pipeline or switch to case-insensitive comparison.
