Send Text Message
Send a freeform text WhatsApp message from one of your workspace senders. Freeform text requires an open 24-hour customer-care window (unless check_window is false); outside the window send an approved template instead.
Returns 200 with status: sent when the provider accepted the message immediately, or 202 with status: pending when it was queued to the async engine. Treat both as success and rely on delivery webhooks for the final state.
