How to Initiate a Cobrowse Session Programmatically via Genesys Cloud Conversations API

What You Will Build

  • You will build a Python script that initiates a cobrowse session for a specific user or queue, returning the session details required to embed the cobrowse widget in a frontend application.
  • This tutorial uses the Genesys Cloud Conversations API (/api/v2/conversations/cobrowses) and the genesys-cloud-purecloud-platform-client Python SDK.
  • The implementation covers Python, with notes for JavaScript/TypeScript adaptation.

Prerequisites

  • OAuth Client Type: A Genesys Cloud OAuth Client with the api grant type.
  • Required Scopes: cobrowse:session:write is mandatory for creating sessions. cobrowse:session:read is recommended for debugging.
  • SDK Version: genesys-cloud-purecloud-platform-client >= 2.0.0 (v2 API compatibility).
  • Language/Runtime: Python 3.8+ or Node.js 16+.
  • External Dependencies:
    • Python: pip install genesys-cloud-purecloud-platform-client
    • JavaScript: npm install @genesys/purecloud-platform-client-sdk

Authentication Setup

Genesys Cloud APIs require OAuth 2.0 Bearer tokens. For server-side integrations, the Client Credentials Flow is the standard. You must cache the token and handle expiration, as tokens are valid for 3600 seconds (1 hour) by default.

Below is a robust authentication helper using the Python SDK. The SDK handles token caching automatically if you configure the config object correctly, but understanding the underlying flow is critical for debugging 401 errors.

import os
from purecloud_platform_client import Configuration, ApiClient
from purecloud_platform_client.rest import ApiException

def get_purecloud_api_client() -> ApiClient:
    """
    Configures and returns a PureCloud API Client instance.
    Handles OAuth2 client credentials flow.
    """
    # Load credentials from environment variables
    client_id = os.getenv("GENESYS_CLIENT_ID")
    client_secret = os.getenv("GENESYS_CLIENT_SECRET")
    environment = os.getenv("GENESYS_ENVIRONMENT", "mypurecloud.com")

    if not client_id or not client_secret:
        raise ValueError("GENESYS_CLIENT_ID and GENESYS_CLIENT_SECRET environment variables are required.")

    # Configure the SDK
    config = Configuration(
        host=f"https://{environment}",
        client_id=client_id,
        client_secret=client_secret
    )

    # The SDK automatically manages token refresh if the token is stored in the config
    # However, for explicit control, we can instantiate the client
    api_client = ApiClient(config)
    
    return api_client

Critical Note on Scopes: Ensure your OAuth Client in the Genesys Cloud Admin portal has the cobrowse:session:write scope assigned. If you receive a 403 Forbidden with a message about insufficient permissions, this is the first place to check.

Implementation

Step 1: Initialize the Conversations API Client

You need to instantiate the ConversationApi class. This class exposes all methods related to conversations, including cobrowse, chat, voice, and video.

from purecloud_platform_client import ConversationApi, CobrowseSessionCreateRequest, CobrowseSessionType

def create_conversation_api_client():
    """
    Creates a ConversationApi instance using the authenticated client.
    """
    api_client = get_purecloud_api_client()
    conversation_api = ConversationApi(api_client)
    return conversation_api

Step 2: Construct the Cobrowse Session Request

The core of the operation is the POST /api/v2/conversations/cobrowses endpoint. The request body must specify the type of the session. The two primary types are:

  1. user: Initiates a cobrowse session with a specific Genesys Cloud user (e.g., an agent).
  2. queue: Initiates a cobrowse session where the initiator is routed to an available agent in a specific queue.

For this tutorial, we will implement the user type, as it is the most common programmatic use case (e.g., an admin tool initiating a session with a specific agent for training).

Required Fields:

  • type: String ("user" or "queue").
  • userId (if type is user): The UUID of the target user.
  • routingData (optional but recommended): Allows you to pass custom attributes to the session.
def build_cobrowse_request(target_user_id: str, session_type: str = "user") -> CobrowseSessionCreateRequest:
    """
    Builds the request body for creating a cobrowse session.
    
    Args:
        target_user_id: The UUID of the user to cobrowse with.
        session_type: Either 'user' or 'queue'.
    
    Returns:
        CobrowseSessionCreateRequest object.
    """
    request_body = CobrowseSessionCreateRequest()
    
    if session_type == "user":
        request_body.type = "user"
        request_body.user_id = target_user_id
    elif session_type == "queue":
        request_body.type = "queue"
        # If using queue, you might need to specify queue_id in routing_data or via query params depending on SDK version
        # For simplicity, this example focuses on user-to-user
        raise NotImplementedError("Queue-based cobrowse initiation requires additional routing configuration.")
    else:
        raise ValueError(f"Unsupported session type: {session_type}")

    return request_body

Step 3: Execute the API Call and Handle Errors

Now we combine the authentication and request construction into a single function that executes the API call. We must handle ApiException to catch HTTP errors such as 400 Bad Request, 401 Unauthorized, 403 Forbidden, and 429 Too Many Requests.

import logging

logger = logging.getLogger(__name__)

def initiate_cobrowse_session(target_user_id: str) -> dict:
    """
    Initiates a cobrowse session with the specified user.
    
    Args:
        target_user_id: The UUID of the target agent/user.
        
    Returns:
        A dictionary containing the session details (sessionId, joinUrl, etc.).
    """
    conversation_api = create_conversation_api_client()
    request_body = build_cobrowse_request(target_user_id)

    try:
        # The SDK method for POST /api/v2/conversations/cobrowses
        # Note: The SDK method name is typically post_conversations_cobrowses
        response = conversation_api.post_conversations_cobrowses(
            body=request_body
        )
        
        logger.info(f"Cobrowse session initiated successfully. Session ID: {response.session_id}")
        
        # Convert the SDK response object to a dictionary for easier handling
        # The response object usually contains: session_id, join_url, initiator_id, etc.
        return response.to_dict()
        
    except ApiException as e:
        logger.error(f"Exception when calling ConversationApi->post_conversations_cobrowses: {e}")
        
        # Specific error handling
        if e.status == 400:
            logger.error("Bad Request. Check if the user_id is valid and the user exists.")
        elif e.status == 401:
            logger.error("Unauthorized. Check your OAuth token and client credentials.")
        elif e.status == 403:
            logger.error("Forbidden. Ensure the OAuth client has 'cobrowse:session:write' scope.")
        elif e.status == 429:
            logger.warning("Rate Limited. Implement exponential backoff.")
        elif e.status == 404:
            logger.error("Not Found. The user ID provided does not exist.")
            
        raise e

Common Errors & Debugging

Error: 403 Forbidden - Insufficient Scope

Cause: The OAuth Client used in the script does not have the cobrowse:session:write scope.
Fix:

  1. Log in to the Genesys Cloud Admin Portal.
  2. Navigate to Platform > OAuth Clients.
  3. Select your client.
  4. Go to the Scopes tab.
  5. Search for cobrowse:session:write and add it.
  6. Important: You must re-authenticate or refresh your OAuth token for the new scope to take effect.

Error: 400 Bad Request - Invalid User ID

Cause: The user_id provided in the request body is not a valid UUID format, or the user does not exist in the Genesys Cloud organization.
Fix:

  1. Verify the UUID format (e.g., 123e4567-e89b-12d3-a456-426614174000).
  2. Use the GET /api/v2/users/{userId} endpoint to confirm the user exists and is active.

Error: 404 Not Found - Resource Not Found

Cause: The target user ID exists but may be disabled, or the cobrowse feature is not enabled for the organization.
Fix:

  1. Check if the user is active in the Admin Portal.
  2. Verify that Cobrowse is licensed and enabled for your organization under Admin > Features.

Error: 429 Too Many Requests

Cause: You have exceeded the rate limit for the Conversations API. Genesys Cloud enforces rate limits to protect system stability.
Fix: Implement exponential backoff. The Python SDK does not automatically retry 429s, so you must handle this in your application logic.

import time

def initiate_cobrowse_with_retry(target_user_id: str, max_retries: int = 3):
    for attempt in range(max_retries):
        try:
            return initiate_cobrowse(target_user_id)
        except ApiException as e:
            if e.status == 429:
                wait_time = 2 ** attempt  # Exponential backoff: 1s, 2s, 4s
                logger.warning(f"Rate limited. Waiting {wait_time} seconds before retry...")
                time.sleep(wait_time)
            else:
                raise e
    raise Exception("Max retries exceeded for cobrowse initiation.")
