Get pricing analytics

Message volume and approximate cost for one connected WhatsApp number, read live from Meta's `pricing_analytics` on the WhatsApp Business Account and scoped to that account's phone number. Meta's figures are approximate and can lag; Meta bills from its own invoice. Meta limits how far back and how fine the data goes (for example HALF_HOUR only over short ranges) and answers out-of-range requests with an error.

List iMessage audience

Contacts who have messaged your iMessage senders (1:1 threads), with subscription state and, for threads opened through a tracked opt-in link, the parameters that brought them in. Newest activity first.
