Sends up to 100 independent SMS messages in one request. Each item is a complete send request with its own recipient, content, ID, status, and cost. For a single message, use Send an SMS message instead.

Acceptance is all-or-nothing: every item is validated before any is queued, and one invalid item rejects the whole batch with a 422 (nothing is sent). A batch from a workspace with no wallet balance fails with a 402. The 202 response lists the accepted messages in submission order; each delivers asynchronously and is tracked individually, like a single send.
