}Send a Text
Sends one SMS to one phone number, either from a pre-approved template (templateId + variables) or as free-form text (message). Send exactly one of templateId or message; a body with both, or with neither, is a 400. A 200 means the message was accepted and queued, not yet delivered, so use the returned messageId with the status endpoint. Sandbox API keys are rejected.
