Looking for advice on how to correctly structure the request for initiating a cobrowse session using the Python SDK. I am trying to programmatically start a cobrowse session for an existing conversation.
Using this snippet:
from purecloud_platform_client import PureCloudPlatformClientV2
api_instance = PureCloudPlatformClientV2()
# Assume auth is handled
conversation_id = 'some-conv-id'
body = {
'type': 'cobrowse',
'target': 'agent', # or 'customer'?
'initiator': 'agent'
}
try:
result = api_instance.conversations_api.post_conversations_cobrowse_session(conversation_id, body=body)
except Exception as e:
print(f"Error: {e}")
The API call fails with a 400 Bad Request. The error message is vague: Validation failed for object 'CobrowseSessionRequest'.
The documentation for POST /api/v2/conversations/{conversationId}/cobrowse/sessions is sparse. It lists required fields but doesn’t show a full example payload for the Python SDK. I suspect the target or initiator enums are incorrect.
How should the body dictionary be structured? Is there a specific session token or cobrowseId I need to generate first? Any working examples for this endpoint in Python would be appreciated.
The documentation actually says target requires a specific type and id structure. You are missing the nested object for the participant or widget. Use this payload instead:
Have you tried verifying that the conversation_id you are passing to the target.id field is actually the ID of the specific participant within the conversation, rather than the conversation ID itself? The suggestion above is close, but the Genesys Cloud API is strict about object types. If you pass a conversation ID where a participant ID is expected, you will still get a 400 Bad Request because the platform cannot resolve the target for the cobrowse session.
In my AWS Lambda handlers for event-driven cobrowse initiation, I always fetch the participant list first. This ensures I have the correct participantId. Here is how I structure that logic in Python using the SDK:
from purecloud_platform_client import PureCloudPlatformClientV2
api_instance = PureCloudPlatformClientV2()
# 1. Fetch participants to get the correct ID
participants_resp = api_instance.conversation_api.get_conversations_participants(conversation_id)
# Assuming we want the first human participant
target_participant_id = participants_resp.entities[0].id
# 2. Construct the body with the correct participant ID
body = {
'type': 'cobrowse',
'target': {
'type': 'participant',
'id': target_participant_id # Critical: Must be participant ID, not conversation ID
}
}
# 3. Initiate the session
try:
result = api_instance.cobrowse_api.post_cobrowse_sessions(body)
print(f"Session initiated: {result.id}")
except Exception as e:
print(f"Failed to initiate: {e}")
Also, double-check your OAuth scopes. You need cobrowse:write for this operation. I run these calls from behind an API Gateway with a Lambda authorizer that validates the scope before allowing the request. If you are getting a 400, it is almost certainly a payload structure issue. If you are getting a 403, then it is the scope. I see this pattern often when developers copy-paste examples without verifying the ID type.
The simplest way to resolve this is to query /api/v2/conversations/{id}/participants first. extract the specific id from the participant object, not the conversation root. the target.id strictly expects that participant uuid. sending the conversation id fails validation. use that nested id in your payload.
Have you tried fetching the participant ID via platformClient.ConversationsApi.getConversationParticipants(conversationId) first? The 400 error persists because target.id requires the specific participant UUID, not the conversation root.
