Channel | WhatsApp Business

With more than 2 billion people using WhatsApp around the world to send 60 billion messages every day, the chat app has revolutionized the way we communicate. With an enterprise-grade API, companies can now send notifications and provide customer service through WhatsApp in a secure, reliable, and customer-friendly way.

List Messages

List messages provide a more straightforward and consistent format than text-based lists for people to find and select what they want from a business.

Lists messages do not require a template or pre-approval.

Benefits and use cases include

  • Provide up to 10 options
  • List messages can be populated dynamically based on a customer’s responses and can be used for personalized bot use cases, such as a take-out menu, a selection of nearby stores or locations, available reservation times, seating choices, etc. 
  • Dedicated description lines for each option are available to provide additional context.

Implementation considerations

  • List messages are most effective for menus with up to 10 options or where additional context is required to make the decision.
  • List messages can provide an initial response to a customer message before transitioning to a human agent. They can be ‘chained’ in a flow with another list or Reply buttons to complete an action.
  • Payload and title on the list rows are mandatory.
  • When more than 1 section is used, the section title is mandatory.
  • Do NOT list messages for:
    • A list of products: List messages cannot contain images.
    • Messages with fewer than four options that require no context (e.g., Yes/No). Use Reply buttons or interactive notifications for these cases.
