About Sent

Sent is a unified messaging API that lets developers integrate and send messages across SMS and app channels (WhatsApp, iMessage, RCS) through a single RESTful interface. It centralizes channel selection, templating, and delivery so teams can send 2FA codes, transactional notifications, and marketing campaigns without building separate integrations for each provider. Sent provides SDKs and libraries (including a Node library) and webhook-based delivery receipts to speed implementation and monitor message status. The platform emphasizes rapid onboarding — "get started in minutes" — and simplifies cross-channel messaging workflows and compliance considerations.
