Trying to kick off an outbound call via the Personal Connection API. The docs say POST /api/v2/external-campaigns/connections/{connectionId}/outbound-calls is the way to go, but I’m hitting a 400 Bad Request. The connection is active and linked to the right user. Here’s the payload I’m sending:
{
“fromAddress”: “tel:+15550100”,
“toAddress”: “tel:+15550199”,
“callbackUrl”: “应用宝官网-全网最新最热手机应用游戏下载”
}
The error response just says “Invalid request body” without pointing to a specific field. I’ve checked the address format and it matches the examples in the swagger spec. Is there a hidden requirement for the callback URL or the user’s provisioning status that isn’t documented? Also, does the user need explicit permission to make outbound calls through this endpoint, or is that handled by the role assignment alone?
