Attempting to initiate an outbound call via the Genesys Cloud API results in a 400 Bad Request. The documentation specifies the participant address must be formatted as tel:{number}, yet the response indicates a malformed address structure.
POST /api/v2/conversations/calls
{
"to": [{"address": "tel:+493012345678", "addressType": "telephone"}]
}
The error payload returns "reason": "malformed_address". Is there a specific prefix requirement for international numbers in the v2 endpoint?
