Build WhatsApp message templates that get approved fast, with the right category, variables, and formatting.

Use buttons, lists, and CTAs to build fast, low-friction WhatsApp conversations with clean UX.

Common, reusable USSD menu structures with worked examples — menus, input capture, pagination, and confirmation.

Gracefully handle USSD timeouts, invalid input, and failures so users never get stuck.
