Send call events
You send WhatsApp call events, such as connecting or ending a call, using the
SendWhatsAppCallEvent operation. AWS End User Messaging passes the call event through to Meta's
calling API. The operation returns the call identifier that Meta assigns to the call.
The request includes the origination phone number, the version of the Meta Graph API to
use, and the call event. The call event is a JSON payload in the format defined by Meta's calling
API, and AWS End User Messaging passes it through without modification. The Meta Graph API version and the
call event format are defined by Meta. For the call event schema and supported API versions, see
the WhatsApp calling
documentation
