Signing Up

You will need a WhatsApp-enabled phone number, also referred to as a WhatsApp Sender. To get started, head over to the Messaging section of the Twilio Console and navigate to Senders > WhatsApp senders on the side menu. Once there, you'll see one of the following options to begin the sign up process:

  • Select a phone number to register: By default, you'll have access to the Self Sign-up process. This is a fully self-service process to register an existing Twilio phone number or bring your own number (BYON).
  • Submit your first WhatsApp Sender: If you are an ISV, SI or if you registered for WhatsApp prior to 2022, you will use the Guided Signup process to "Submit a WhatsApp Sender". Note: It takes around 2-5 business days for approval from WhatsApp.

Once you have an approved WhatsApp Sender, continue on below to to get started with a WhatsApp Quickstart in the language of your choice!

This purpose-built API lets you start sending OTPs right away, without throttling and other restrictions that make successful implementation difficult or even impossible.

Two-way messaging with WhatsApp

If you're looking to build conversational or back-and-forth messaging with WhatsApp, we recommend the Twilio Conversations API. With Twilio Conversations, you can build two-way messaging experiences that are cross-channel. So in addition to building WhatsApp-only Conversations, you can also build one customer experience with WhatsApp, SMS, MMS, and browser-based or mobile chat messages.
