Launch WhatsApp faster with Twilio: Senders API GA, plus Typing Indicators, Flows, and a smoother ISV experience

November 19, 2025

The WhatsApp Senders API is Generally Available

Your customers live on WhatsApp. We’re making it easier to meet them there, and keep conversations fast, helpful, and on brand

Today, we’re expanding WhatsApp support so you can launch quicker and scale with less lift. The WhatsApp Senders API is Generally Available, Typing Indicators and WhatsApp Flows are supported through Twilio, and Tech Provider Program onboarding in Console is cleaner for ISVs.

Less friction. Better engagement. More momentum.

Senders API is now GA

Think of the Senders API as the easy button for onboarding WhatsApp at scale. Instead of clicking through forms or juggling tools, you can manage more of the full sender lifecycle with code.

What you can do

  • Create and register WhatsApp senders programmatically

  • Verify ownership programmatically with SMS or alternatively via voice OTP

  • Fetch, list, and update sender profiles and webhooks

  • Retire numbers cleanly when you’re done

Why it matters

  • Built for scale across subaccounts, ideal for ISVs and enterprises managing lots of numbers

  • No Meta Business Suite login required when you use the API through Twilio

  • Cross‑channel foundation: WhatsApp is GA, RCS is supported, with more channels planned

Good to know

  • The Senders API handles registration; send messages with Twilio Programmable Messaging API or Conversations API

  • Numbers must support SMS or voice for OTP verification

  • Some edge cases may still require a Console step or Meta‑side action

Other recent updates 

  • Typing Indicators: Let customers know a reply is in progress while you route to an agent, fetch data, or generate a response. This lowers perceived wait time and can lift CSAT.

  • WhatsApp Flows support: Ship multi‑screen, in‑thread experiences, guided product discovery, appointment booking, onboarding forms. Use in session or as approved templates (WhatsApp/flows), and pass data via endpoints for personalization. 

  • Tech Provider Program (ISV) updates: We’ve revamped TPP onboarding in Console and significantly improved our docs. A quick account quiz routes users to the right path (ISV vs. direct) and blocks ineligible TPP requests. ISVs now get a dedicated WhatsApp Senders page and can create senders only from the parent account, closing gaps like subaccount Terms of Service misapplication. The result: fewer misconfigs and tickets, cleaner setups, and faster activations.

Why Twilio for WhatsApp

Here’s why teams choose Twilio to turn WhatsApp into a growth channel, not just another inbox.

  • Faster go‑live: Automated onboarding, template management, and branded sender verification help you launch quickly and stay aligned with global standards.

  • Effortless scale: Run high‑throughput programs across regions and teams with Twilio’s global platform. Orchestrate campaigns and customer care without rebuilding workflows as you grow.

  • One platform, every channel: Manage WhatsApp alongside SMS, RCS, voice, email, and more. Escalate to an agent or a voice call from the same conversation and keep context the whole way.

  • See what works, optimize fast: Real‑time analytics and insights track every interaction so you can tune journeys, personalize at scale, and prove impact.

  • Built for builders: Clear docs, SDKs, and Code Exchange templates help you ship faster and adapt without vendor lock‑in.
