Send a WhatsApp template message
Queues a template message on one of your WhatsApp connections and returns immediately with a log_id. Delivery is asynchronous — track it through your provider’s delivery webhooks.
Which fields are required depends on the connection: AiSensy Campaign connections need campaign_name; every other connection needs template_name and language_code.
to is parsed, not pattern-matched, and carries no default country — it must include its own country code.
