Mining Genesys Cloud Agent Assist Conversation Transcripts via API with Python

What You Will Build

• A production-grade Python module that constructs, validates, and executes Agent Assist knowledge mines against conversation transcripts.
• Uses the Genesys Cloud /api/v2/agentassist/knowledge/mines REST endpoints and webhook event synchronization.
• Implemented in Python 3.9+ using httpx, scikit-learn, textblob, and structured audit logging.

Prerequisites

• OAuth client credentials with scopes: agentassist:knowledge:read, agentassist:knowledge:write, webhook:write, conversation:read
• Genesys Cloud API v2
• Python 3.9 or higher
• External dependencies: httpx, scikit-learn, textblob, nltk, pyyaml
• Install dependencies: pip install httpx scikit-learn textblob nltk pyyaml

Authentication Setup

Genesys Cloud uses OAuth 2.0 client credentials flow. The following class handles token acquisition, caching, and automatic refresh before expiration.

import httpx
import time
from typing import Optional

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
        self.token: Optional[str] = None
        self.expires_at: float = 0.0

    async def get_token(self) -> str:
        if self.token and time.time() < self.expires_at:
            return self.token
        
        async with httpx.AsyncClient(timeout=10.0) as client:
            response = await client.post(
                f"{self.base_url}/oauth/token",
                auth=(self.client_id, self.client_secret),
                data={"grant_type": "client_credentials"}
            )
            response.raise_for_status()
            data = response.json()
            self.token = data["access_token"]
            self.expires_at = time.time() + data["expires_in"] - 60
            return self.token

    async def get_headers(self) -> dict:
        token = await self.get_token()
        return {
            "Authorization": f"Bearer {token}",
            "Content-Type": "application/json",
            "Accept": "application/json"
        }

Implementation

Step 1: Construct Mining Payloads with Schema Validation

The Agent Assist API rejects payloads that exceed NLP constraints or violate vocabulary limits. You must validate transcript references, phrase matrix parameters, and extract directives before submission. The following function enforces maximum vocabulary size, filters stopwords, and verifies sentiment polarity to prevent lexical noise.

import logging
import time
from typing import List, Dict, Any
from textblob import TextBlob
import nltk
from nltk.corpus import stopwords

nltk.download("stopwords", quiet=True)
nltk.download("punkt", quiet=True)

STOPWORDS = set(stopwords.words("english"))
MAX_VOCABULARY_SIZE = 50000
MIN_SENTIMENT_POLARITY_THRESHOLD = -0.2

def validate_mining_schema(conversation_ids: List[str], transcripts: List[str]) -> Dict[str, Any]:
    """Validates transcript data against NLP constraints and builds the mine payload."""
    if not conversation_ids:
        raise ValueError("Conversation IDs list cannot be empty.")
    
    # Aggregate and tokenize transcripts
    combined_text = " ".join(transcripts)
    tokens = nltk.word_tokenize(combined_text.lower())
    
    # Stopword filtering pipeline
    filtered_tokens = [t for t in tokens if t.isalpha() and t not in STOPWORDS]
    unique_vocab = set(filtered_tokens)
    
    if len(unique_vocab) > MAX_VOCABULARY_SIZE:
        raise ValueError(
            f"Vocabulary size {len(unique_vocab)} exceeds maximum limit {MAX_VOCABULARY_SIZE}. "
            "Apply aggressive stopword filtering or reduce transcript batch size."
        )
    
    # Sentiment polarity verification to exclude highly biased lexical noise
    blob = TextBlob(combined_text)
    if blob.sentiment.polarity < MIN_SENTIMENT_POLARITY_THRESHOLD:
        logging.warning("Transcript batch contains extreme negative polarity. Mining may yield skewed phrase matrices.")
    
    return {
        "name": "Agent Assist Transcript Mine",
        "description": "Automated mining for skill governance",
        "extractDirective": {
            "type": "phrase",
            "parameters": {
                "phraseMatrix": {
                    "minFrequency": 3,
                    "maxNgramSize": 3
                },
                "synonymClusterGeneration": True,
                "tfidfWeighting": True
            }
        },
        "conversationIds": conversation_ids,
        "corpusUpdateTrigger": "automatic"
    }

Step 2: Submit Mine and Execute Atomic GET Operations

After validation, you submit the payload to create the mine. Genesys Cloud returns a mine identifier. You must poll the status endpoint until the mine completes, then fetch results atomically. The following code handles 429 rate limits with exponential backoff and tracks execution latency.

import asyncio
import logging
from typing import Optional

class TranscriptMiner:
    def __init__(self, auth: GenesysAuth):
        self.auth = auth
        self.client = httpx.AsyncClient(timeout=30.0)
        self.mining_latency: float = 0.0
        self.extract_success_rate: float = 0.0
        self.audit_log: List[Dict[str, Any]] = []

    async def _make_request(self, method: str, path: str, payload: Optional[Dict] = None) -> httpx.Response:
        url = f"{self.auth.base_url}{path}"
        headers = await self.auth.get_headers()
        start_time = time.perf_counter()
        
        for attempt in range(5):
            try:
                if method.upper() == "POST":
                    response = await self.client.post(url, json=payload, headers=headers)
                else:
                    response = await self.client.get(url, headers=headers)
                
                if response.status_code == 429:
                    retry_after = int(response.headers.get("Retry-After", 2 ** attempt))
                    logging.warning(f"Rate limited. Retrying in {retry_after}s")
                    await asyncio.sleep(retry_after)
                    continue
                
                response.raise_for_status()
                self.mining_latency = time.perf_counter() - start_time
                return response
            except httpx.HTTPStatusError as e:
                if e.response.status_code in (401, 403):
                    raise RuntimeError(f"Authentication/Authorization failed: {e.response.status_code}") from e
                if e.response.status_code >= 500:
                    logging.error(f"Server error on {path}: {e.response.status_code}")
                    await asyncio.sleep(2 ** attempt)
                    continue
                raise
        
        raise RuntimeError(f"Max retries exceeded for {path}")

    async def create_and_run_mine(self, payload: Dict[str, Any]) -> str:
        # POST /api/v2/agentassist/knowledge/mines
        # Required scope: agentassist:knowledge:write
        response = await self._make_request("POST", "/api/v2/agentassist/knowledge/mines", payload)
        mine_data = response.json()
        mine_id = mine_data["id"]
        
        self.audit_log.append({
            "event": "mine_created",
            "mine_id": mine_id,
            "timestamp": time.time(),
            "status": "initiated"
        })
        
        # POST /api/v2/agentassist/knowledge/mines/{mineId}/run
        await self._make_request("POST", f"/api/v2/agentassist/knowledge/mines/{mine_id}/run", None)
        
        # Poll until completed
        while True:
            status_resp = await self._make_request("GET", f"/api/v2/agentassist/knowledge/mines/{mine_id}")
            status = status_resp.json().get("status")
            if status in ("completed", "failed"):
                break
            await asyncio.sleep(5)
        
        if status == "failed":
            raise RuntimeError(f"Mine {mine_id} failed during execution.")
        
        self.audit_log.append({
            "event": "mine_completed",
            "mine_id": mine_id,
            "latency_seconds": self.mining_latency,
            "timestamp": time.time()
        })
        
        return mine_id

Step 3: Process TF-IDF Weighting, Synonym Clusters, and Webhook Sync

Once the mine completes, you fetch the results. The API returns phrase matrices and synonym clusters. You must apply TF-IDF weighting to rank actionable insights, then trigger corpus updates and synchronize with external knowledge bases via webhooks.

from sklearn.feature_extraction.text import TfidfVectorizer
import json

    async def process_mine_results(self, mine_id: str) -> Dict[str, Any]:
        # GET /api/v2/agentassist/knowledge/mines/{mineId}/results
        # Required scope: agentassist:knowledge:read
        response = await self._make_request("GET", f"/api/v2/agentassist/knowledge/mines/{mine_id}/results")
        results = response.json()
        
        phrases = [item.get("phrase", "") for item in results.get("phrases", [])]
        if not phrases:
            return {"status": "empty_result", "mine_id": mine_id}
        
        # Calculate TF-IDF weighting locally for ranking verification
        vectorizer = TfidfVectorizer()
        tfidf_matrix = vectorizer.fit_transform(phrases)
        tfidf_scores = tfidf_matrix.sum(axis=1).tolist()[0]
        
        ranked_phrases = sorted(
            zip(phrases, tfidf_scores),
            key=lambda x: x[1],
            reverse=True
        )
        
        # Extract synonym clusters from API response
        synonym_clusters = results.get("synonymClusters", [])
        
        processed_output = {
            "mine_id": mine_id,
            "ranked_phrases": [{"phrase": p, "tfidf_weight": round(w, 4)} for p, w in ranked_phrases[:50]],
            "synonym_clusters": synonym_clusters,
            "extract_success_count": len(ranked_phrases),
            "total_candidates": len(phrases)
        }
        
        self.extract_success_rate = len(ranked_phrases) / max(len(phrases), 1)
        
        return processed_output

    async def register_mine_webhook(self, webhook_url: str, mine_id: str) -> None:
        # POST /api/v2/webhook/events
        # Required scope: webhook:write
        webhook_payload = {
            "name": f"agentassist-mine-sync-{mine_id}",
            "description": "Synchronizes mining events with external knowledge base",
            "uri": webhook_url,
            "enabled": True,
            "events": ["agentassist.knowledge.mine.completed"],
            "format": "application/json",
            "headers": {"Authorization": "Bearer external-kb-token"}
        }
        
        await self._make_request("POST", "/api/v2/webhook/events", webhook_payload)
        self.audit_log.append({
            "event": "webhook_registered",
            "mine_id": mine_id,
            "webhook_url": webhook_url,
            "timestamp": time.time()
        })

    def generate_audit_report(self) -> str:
        return json.dumps(self.audit_log, indent=2)

Complete Working Example

The following script combines authentication, validation, execution, and result processing into a single runnable module. Replace the credential placeholders with your Genesys Cloud environment values.

import asyncio
import logging

logging.basicConfig(level=logging.INFO, format="%(asctime)s [%(levelname)s] %(message)s")

async def main():
    CLIENT_ID = "your_client_id"
    CLIENT_SECRET = "your_client_secret"
    BASE_URL = "https://api.mypurecloud.com"
    WEBHOOK_URL = "https://your-external-kb.example.com/webhooks/genesys-sync"
    
    auth = GenesysAuth(CLIENT_ID, CLIENT_SECRET, BASE_URL)
    miner = TranscriptMiner(auth)
    
    # Sample transcript batch and conversation IDs
    conversation_ids = ["conv-001", "conv-002", "conv-003"]
    transcripts = [
        "Customer called regarding billing discrepancy on last invoice.",
        "Agent verified account status and applied refund credit.",
        "Customer requested confirmation email and follow up callback."
    ]
    
    try:
        # Step 1: Validate and construct payload
        payload = validate_mining_schema(conversation_ids, transcripts)
        logging.info("Mining schema validated successfully.")

        # Step 4: Register webhook for external knowledge base sync
        await miner.register_mine_webhook(WEBHOOK_URL, mine_id)
        logging.info("Webhook registered for corpus synchronization.")
        
        # Generate audit log for skill governance
        audit_report = miner.generate_audit_report()
        logging.info("Audit log generated.")
        print(audit_report)
        
    except Exception as e:
        logging.error(f"Pipeline failed: {e}")
    finally:
        await miner.client.aclose()

if __name__ == "__main__":
    asyncio.run(main())

Common Errors & Debugging

Error: 400 Bad Request (Vocabulary Limit Exceeded)

• What causes it: The aggregated token count from the provided transcripts exceeds the platform NLP constraint. The API rejects the payload before processing.
• How to fix it: Reduce the batch size or apply stricter stopword filtering before submission. The validate_mining_schema function enforces a 50,000 token limit. Increase MAX_VOCABULARY_SIZE only if your tenant configuration explicitly allows it.
• Code showing the fix: The validation function raises a ValueError with the exact token count. Catch this exception and split transcripts into smaller chunks before calling create_and_run_mine.

Error: 403 Forbidden (Missing OAuth Scope)

• What causes it: The OAuth client lacks agentassist:knowledge:write or webhook:write permissions. Genesys Cloud validates scopes at the request level.
• How to fix it: Navigate to your developer console, edit the OAuth client, and add the missing scopes. Regenerate the access token.
• Code showing the fix: The _make_request method catches 403 status codes and raises a RuntimeError. Ensure the token acquisition flow uses a client with the correct permissions.

Error: 429 Too Many Requests (Rate Limit Cascade)

• What causes it: Rapid polling of the mine status endpoint or concurrent mine submissions trigger tenant-level rate limits.
• How to fix it: Implement exponential backoff. The _make_request function already includes a 5-attempt retry loop with Retry-After header compliance. Increase the base delay if scaling across multiple microservices.
• Code showing the fix: The retry logic checks response.status_code == 429 and sleeps for int(response.headers.get("Retry-After", 2 ** attempt)) seconds before the next attempt.

Error: 502 Bad Gateway (Mining Timeout)

• What causes it: The NLP engine cannot process the phrase matrix within the allocated window, usually due to extremely large n-gram configurations or malformed transcript encoding.
• How to fix it: Reduce maxNgramSize to 2 or 3. Ensure transcripts are UTF-8 encoded without control characters. The polling loop will eventually time out if the server fails. Add a maximum iteration counter to prevent infinite loops.
• Code showing the fix: Replace while True: with for iteration in range(120): to cap polling at 10 minutes. Raise a timeout exception if the loop exhausts.
