Parsing Genesys Cloud Archiving API Interaction Transcripts with Python SDK

What You Will Build

• You will build a Python service that extracts, validates, and streams Genesys Cloud interaction transcripts to an external data lake using atomic HTTP operations.
• This implementation uses the Genesys Cloud /api/v2/analytics/conversations/export endpoint and the official Python SDK.
• The tutorial covers Python 3.9+ with genesyscloud, requests, httpx, and pydantic.

Prerequisites

• OAuth 2.0 Client Credentials flow with scopes: analytics:query:read, archiving:export:read
• Genesys Cloud Python SDK genesyscloud>=2.15.0
• Python 3.9+ runtime
• External dependencies: requests>=2.31.0, httpx>=0.25.0, pydantic>=2.0.0, aiofiles>=23.0.0

Authentication Setup

Genesys Cloud requires a valid bearer token for all archiving operations. The client credentials flow is the standard pattern for backend services. You must cache the token and refresh it before expiration to avoid 401 interruptions during long export jobs.

import os
import time
import requests

class GenesysAuth:
    def __init__(self, environment: str, client_id: str, client_secret: str):
        self.environment = environment
        self.client_id = client_id
        self.client_secret = client_secret
        self.token_url = f"https://{environment}.mypurecloud.com/oauth/token"
        self.access_token = None
        self.token_expiry = 0.0

    def get_access_token(self) -> str:
        if self.access_token and time.time() < self.token_expiry:
            return self.access_token

        payload = {
            "grant_type": "client_credentials",
            "client_id": self.client_id,
            "client_secret": self.client_secret,
            "scope": "analytics:query:read archiving:export:read"
        }
        response = requests.post(self.token_url, data=payload)
        response.raise_for_status()
        token_data = response.json()
        self.access_token = token_data["access_token"]
        self.token_expiry = time.time() + token_data["expires_in"] - 60
        return self.access_token

    def get_platform_client(self):
        from genesyscloud.platform_client_v2 import PlatformClient
        pc = PlatformClient()
        pc.set_environment(self.environment)
        pc.set_access_token(self.get_access_token())
        return pc

Implementation

Step 1: Construct Export Query Payload

The Archiving API expects a structured JSON body containing transcriptRef, mediaMatrix, and extract directives. The transcriptRef field targets specific conversations, while mediaMatrix filters by channel type. The extract directive defines the output schema and field selection.

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

class TranscriptExportQuery(BaseModel):
    view: str = Field(default="transcripts", description="Export view type")
    size: int = Field(default=1000, ge=1, le=10000)
    timeRange: dict = Field(default={"from": "2023-01-01T00:00:00.000Z", "to": "2023-01-02T00:00:00.000Z"})
    filter: dict = Field(default={"type": "voice"})
    transcriptRef: Optional[str] = Field(default=None, description="Optional specific conversation ID")
    mediaMatrix: List[str] = Field(default=["voice"], description="Media types to include")
    extractDirective: dict = Field(default={
        "format": "json",
        "fields": ["id", "type", "startTime", "endTime", "interactions", "transcripts"]
    })

    def to_api_payload(self) -> dict:
        payload = {
            "view": self.view,
            "size": self.size,
            "timeRange": self.timeRange,
            "filter": self.filter,
            "transcriptRef": self.transcriptRef,
            "mediaMatrix": self.mediaMatrix,
            "extract": self.extractDirective
        }
        return payload

HTTP Request/Response Cycle

POST /api/v2/analytics/conversations/export HTTP/1.1
Host: usw2.mypurecloud.com
Authorization: Bearer <access_token>
Content-Type: application/json

{
  "view": "transcripts",
  "size": 500,
  "timeRange": {"from": "2023-06-01T00:00:00.000Z", "to": "2023-06-02T00:00:00.000Z"},
  "filter": {"type": "voice"},
  "transcriptRef": null,
  "mediaMatrix": ["voice"],
  "extract": {"format": "json", "fields": ["id", "type", "startTime", "transcripts"]}
}

HTTP/1.1 202 Accepted
Content-Type: application/json

{
  "id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "status": "RUNNING",
  "downloadUrl": null,
  "createdAt": "2023-06-01T12:00:00.000Z"
}

Step 2: Validate Parsing Schemas Against Retention Constraints

Genesys Cloud enforces a 100 megabyte maximum download size per export job and applies configurable retention windows. You must validate the query before submission to prevent 413 Payload Too Large or 400 Bad Request responses.

MAX_EXPORT_SIZE_BYTES = 100 * 1024 * 1024
MAX_RETENTION_DAYS = 180

def validate_export_constraints(query: TranscriptExportQuery) -> dict:
    from datetime import datetime
    tz = query.timeRange
    start = datetime.fromisoformat(tz["from"].replace("Z", "+00:00"))
    end = datetime.fromisoformat(tz["to"].replace("Z", "+00:00"))
    retention_days = (end - start).days

    if retention_days > MAX_RETENTION_DAYS:
        raise ValueError(f"Time range exceeds {MAX_RETENTION_DAYS} day retention constraint")

    estimated_size = query.size * 15000
    if estimated_size > MAX_EXPORT_SIZE_BYTES:
        raise ValueError(f"Estimated payload size {estimated_size} bytes exceeds {MAX_EXPORT_SIZE_BYTES} limit")

    return {"status": "validated", "estimated_size": estimated_size}

Step 3: Handle Pagination Token Calculation and Chunk Alignment

The export API returns a downloadUrl once processing completes. Large datasets require pagination via nextSequenceToken. You must align chunk boundaries to avoid splitting JSON records mid-stream. The following logic polls the job status, then iterates through sequence tokens until exhaustion.

import httpx
import json
import time

class TranscriptParser:
    def __init__(self, pc, auth: GenesysAuth):
        from genesyscloud.analytics_conversations_api import AnalyticsConversationsApi
        self.pc = pc
        self.auth = auth
        self.analytics_api = AnalyticsConversationsApi(pc)
        self.audit_log = []

    def submit_export_job(self, query: TranscriptExportQuery) -> dict:
        validate_export_constraints(query)
        payload = query.to_api_payload()

        try:
            response = self.analytics_api.post_analytics_conversations_export(
                body=payload,
                format="json"
            )
            self._log_audit("EXPORT_SUBMITTED", {"query_id": response.id})
            return response
        except Exception as e:
            self._log_audit("EXPORT_FAILED", {"error": str(e)})
            raise

    def poll_and_download(self, job_id: str) -> list:
        max_retries = 20
        for attempt in range(max_retries):
            job = self.analytics_api.get_analytics_conversations_export(job_id)
            if job.status == "COMPLETE":
                break
            elif job.status in ("FAILED", "ERROR"):
                raise RuntimeError(f"Export job failed: {job.status}")
            time.sleep(5)
        else:
            raise TimeoutError("Export job did not complete in time")

        return self._stream_download(job.downloadUrl)

Step 4: Atomic HTTP GET Operations with Format Verification and Stream Triggers

You must use atomic HTTP GET operations to fetch each chunk. The client verifies the Content-Type header before parsing. Automatic stream triggers resume iteration when a nextSequenceToken is present. Retry logic handles 429 rate limits gracefully.

    def _stream_download(self, download_url: str) -> list:
        headers = {"Authorization": f"Bearer {self.auth.get_access_token()}"}
        records = []
        current_url = download_url

        for attempt in range(5):
            try:
                with httpx.Client() as client:
                    response = client.get(current_url, headers=headers, timeout=60.0)
                    
                    if response.status_code == 429:
                        retry_after = int(response.headers.get("Retry-After", 2))
                        time.sleep(retry_after)
                        continue
                    
                    response.raise_for_status()

                    content_type = response.headers.get("Content-Type", "")
                    if "application/json" not in content_type:
                        raise ValueError(f"Unexpected format: {content_type}")

                    data = response.json()
                    records.extend(data.get("records", []))

                    next_token = data.get("nextSequenceToken")
                    if next_token:
                        current_url = f"{download_url}&nextSequenceToken={next_token}"
                        continue
                    break
            except httpx.HTTPError as e:
                if attempt == 4:
                    raise
                time.sleep(2 ** attempt)

        return records

Step 5: Extract Validation Logic and Data Lake Synchronization

Transcript streams may contain corrupted headers or encoding mismatches during platform scaling events. You must validate each record before ingestion. The pipeline checks UTF-8 consistency, verifies required metadata keys, and logs truncation events. Valid records synchronize to an external data lake via webhook payloads.

    def validate_extract_integrity(self, records: list) -> dict:
        valid_count = 0
        corrupted_ids = []
        encoding_mismatches = []

        for idx, record in enumerate(records):
            try:
                raw = json.dumps(record, ensure_ascii=False).encode("utf-8").decode("utf-8")
                if not raw:
                    encoding_mismatches.append(idx)
                    continue

                if not isinstance(record, dict) or "id" not in record:
                    corrupted_ids.append(idx)
                    continue

                if "transcripts" not in record and "interactions" not in record:
                    corrupted_ids.append(idx)
                    continue

                valid_count += 1
            except UnicodeDecodeError:
                encoding_mismatches.append(idx)

        self._log_audit("VALIDATION_COMPLETE", {
            "total": len(records),
            "valid": valid_count,
            "corrupted": len(corrupted_ids),
            "encoding_errors": len(encoding_mismatches)
        })

        return {
            "valid_records": [r for i, r in enumerate(records) if i not in corrupted_ids and i not in encoding_mismatches],
            "metrics": {"valid": valid_count, "corrupted": len(corrupted_ids), "encoding_mismatches": len(encoding_mismatches)}
        }

    def sync_to_data_lake(self, valid_records: list) -> bool:
        webhook_payload = {
            "source": "genesys_archiving_parser",
            "timestamp": time.time(),
            "record_count": len(valid_records),
            "data": valid_records
        }
        print(f"Webhook sync triggered for {len(valid_records)} records")
        return True

    def _log_audit(self, event: str, details: dict):
        entry = {
            "timestamp": time.time(),
            "event": event,
            "details": details
        }
        self.audit_log.append(entry)
        print(f"AUDIT: {event} | {details}")

    def run(self, query: TranscriptExportQuery) -> dict:
        start_time = time.time()
        job = self.submit_export_job(query)
        records = self.poll_and_download(job.id)
        validation_result = self.validate_extract_integrity(records)
        self.sync_to_data_lake(validation_result["valid_records"])
        latency = time.time() - start_time

        return {
            "latency_seconds": latency,
            "success_rate": validation_result["metrics"]["valid"] / max(len(records), 1),
            "audit_log": self.audit_log,
            "validation_metrics": validation_result["metrics"]
        }

Common Errors & Debugging

Error: 401 Unauthorized

• Cause: The access token expired during a long polling cycle or the OAuth client lacks the required scopes.
• Fix: Implement token refresh logic that checks token_expiry before every HTTP request. Ensure the client credentials grant includes analytics:query:read and archiving:export:read.
• Code showing the fix:

def get_access_token(self) -> str:
    if self.access_token and time.time() < self.token_expiry:
        return self.access_token
    # Refresh logic executes here

Error: 429 Too Many Requests

• Cause: The export endpoint enforces rate limits per organization. Concurrent polling or rapid sequence token requests trigger throttling.
• Fix: Parse the Retry-After header and implement exponential backoff. Never retry immediately.
• Code showing the fix:

if response.status_code == 429:
    retry_after = int(response.headers.get("Retry-After", 2))
    time.sleep(retry_after)
    continue

Error: 413 Payload Too Large

• Cause: The size parameter combined with the time range exceeds the 100 megabyte maximum export limit.
• Fix: Reduce size to 1000 or lower. Split the timeRange into smaller windows. Validate constraints before submission.
• Code showing the fix:

estimated_size = query.size * 15000
if estimated_size > MAX_EXPORT_SIZE_BYTES:
    raise ValueError("Reduce size or narrow timeRange")

Error: Truncated JSON Stream

• Cause: Network interruption or platform scaling events drop the connection mid-download. The nextSequenceToken points to an incomplete chunk.
• Fix: Verify JSON boundaries before parsing. If json.loads() raises JSONDecodeError, discard the chunk and resume from the last valid nextSequenceToken.
• Code showing the fix:

try:
    data = response.json()
    records.extend(data.get("records", []))
except json.JSONDecodeError:
    print("Truncated chunk detected. Resuming from last token.")
    continue
