πŸ”΄ The EASIEST & CHEAPEST way to send messages with your app (SMS/WhatsApp/RCS)
Sending SMS, WhatsApp, and RCS messages should be simple β€” but in the real world, you end up dealing with registrations, approvals, carrier routing, country rules, retries, and webhooks just to answer one question: did the message land?
This video shows how to avoid all of that complexity with Sent, a single API that can route messages across WhatsApp, SMS, and RCS automatically.
Sent handles channel availability, formatting, fallbacks, compliance, delivery states, and webhook updates behind the scenes, so your app can send the right message through the best channel without maintaining separate integrations for each one.
I’ll walk you through a full delivery tracking demo using the Sent's TypeScript SDK, Convex, real webhooks, approved templates, contacts, automatic routing, and AI agent setup with the Sent's MCP Server.
We’ll cover:
βœ… Why sending SMS gets complicated fast
βœ… How Sent routes WhatsApp, SMS, and RCS from one API
βœ… Setting up API keys, webhook secrets, and template IDs
βœ… Sending real WhatsApp and SMS messages from a demo app
βœ… Tracking queued, sent, delivered, and read states in real time
βœ… Using templates, dynamic variables, buttons, and rich WhatsApp messages
βœ… Handling Sent's webhooks with Convex or Next.js route handlers
βœ… Using the Sent's MCP and docs to build faster with AI agents
If you’re building apps that need reliable user messaging, this is one of the cleanest ways I’ve seen to ship multi-channel delivery without fighting every carrier and platform yourself.
