twilio-whatsapp-manage-senders

Overview

A WhatsApp sender is a phone number registered with WhatsApp Business through Twilio. Registration goes through a lifecycle of statuses before becoming ONLINE. Sandbox testing does not require a registered sender — see twilio-whatsapp-send-message.

Prerequisites

• A phone number capable of receiving SMS or voice verification
• Number must not already be registered with WhatsApp
• Environment variables:
  • TWILIO_ACCOUNT_SID
  • TWILIO_AUTH_TOKEN — See twilio-iam-auth-setup for credential setup and best practices
• SDK: pip install twilio / npm install twilio
