I’m trying to push custom attributes from our external CRM into a live voice conversation in Genesys Cloud. The goal is to update the customer_tier and last_call_reason fields on the agent’s participant object so they show up in the agent desktop UI immediately.
I’m using the Python SDK to make the call. Here’s the snippet:
conversation_id = "abc-123-def"
participant_id = "xyz-789-uvw"
# Fetch current participant first to get the eTag
current_participant = client.conversations_api.get_conversation_voice_participant(conversation_id, participant_id)
# Update attributes
updated_attrs = current_participant.attributes.copy()
updated_attrs['customer_tier'] = 'platinum'
updated_attrs['last_call_reason'] = 'billing_issue'
body = models.ParticipantModifyRequest(
attributes=updated_attrs,
etag=current_participant.etag
)
try:
client.conversations_api.patch_conversation_voice_participant(
conversation_id=conversation_id,
participant_id=participant_id,
body=body
)
except Exception as e:
print(f"Failed: {e}")
The request keeps failing with a 400 Bad Request. The error message is generic: {"message": "Validation failed", "errors": [{"message": "Invalid attribute update request"}]}.
I’ve verified that the customer_tier and last_call_reason keys are defined in the Interaction Attributes configuration in the admin UI. They are marked as “writable”. I’m also passing the etag from the GET request, so optimistic locking shouldn’t be the issue. The conversation is active, and the agent is connected.
Is there a specific format required for the attributes dictionary? I’ve tried sending it as a simple dict and as a JSON string, but the SDK seems to handle the serialization. Maybe I’m missing a required field in the ParticipantModifyRequest? The docs are pretty sparse on what constitutes an “invalid” attribute update during a live call.
Any ideas on what’s tripping up the validator? I’ve been staring at this for an hour and the error message isn’t helping much. The API seems to accept updates to wrapup_code just fine, but custom attributes are throwing this validation error every time. I’ve checked the timezone settings on the account and they’re correct for Europe/Berlin, so that’s not it. I’ve also tried using the raw REST endpoint with curl and get the same 400 error. The payload looks identical to the examples in the documentation. I’m running out of things to check. The SDK version is the latest stable release. I’ve cleared the cache and tried different browsers, but it’s an API call, so the browser shouldn’t matter. I’m stuck.
