Getting a 400 Bad Request with "code":"bad_request","message":"Malformed participant address" when initiating outbound calls via /api/v2/conversations/calls. The payload looks standard:
{"from":{"phoneNumber":"+12065551234"},"to":[{"phoneNumber":"+639171234567"}]}
I’ve validated the E.164 format. Is Genesys rejecting the country code or is there a specific formatting rule I’m missing? Need to fix this before tracing the Data Action execution.
