I’m trying to sync customer tier data from our external CRM into a live Genesys Cloud voice conversation. The goal is to update a custom participant attribute called customerTier in real-time so our custom desktop widget can react to it via the event stream.
I have the conversation ID and the participant ID. I’m sending a PATCH request to the endpoint /api/v2/conversations/voice/{conversationId}/participants/{participantId}. The request body looks like this:
{
"attributes": {
"customerTier": "Platinum",
"source": "crm_sync"
}
}
The response is a 400 Bad Request. The error payload is generic:
{
"code": "invalid_request_body",
"message": "Request body is invalid",
"status": "Bad Request",
"errors": []
}
I’ve tried wrapping the attributes in the full participant object structure like this:
{
"name": "External System",
"attributes": {
"customerTier": "Platinum"
}
}
Same 400 error. I’ve also tried just sending the name field to verify the endpoint is reachable, which works fine. It seems specifically tied to the attributes object.
Is there a specific schema requirement for participant attributes that I’m missing? Or is this endpoint strictly for updating routing info and not custom data? I checked the docs and it says attributes are supported, but the validation is failing silently with an empty errors array.
