Trying to push a custom attribute from our CRM into a live voice call using the PATCH endpoint. Getting a 409 Conflict immediately after the initial 202 Accepted. The payload looks standard. Is there a lock on the participant object during active media streams that I’m missing?
PATCH /api/v2/conversations/123/participants/456
{
“attributes”: {
“ext_cust_id”: “99887”
}
}
