With over 2.2 billion monthly users, WhatsApp offers a powerful channel for conversational customer engagement, providing high deliverability, adoption, and engagement rates. The WhatsApp Business API now supports Quick Replies and Call-to-Action buttons, allowing businesses to streamline customer responses and guide them through conversational interactions. With these interactive templates, businesses can offer engaging experiences, such as sending actionable notifications, offering self-service options, and reengaging customers with call-to-action buttons. To get started, businesses need to create and submit a Message Template in the Twilio Console, which will be approved by WhatsApp before being used. With this upgrade, businesses can standardize inbound messages, invoke next steps of a Studio flow, trigger opt-in or opt-out using Twilio's Advanced Opt-Out feature, and more.
