// USSD BUILDER

Build USSD menus without writing code.

Design multi-level interactive menus with payments built in. Three steps to go live on any shortcode.

STEP 1 — ADD YOUR MERCHANT CREDENTIALS
Go to Settings → Payment Integration and enter your Merchant ID and API Key from your payment provider. These are used on all payment nodes in your menus.
STEP 2 — BUILD YOUR MENU TREE
Add menu options and choose a node type for each: message (display text), submenu (nested options), or payment (collect amount + process via your merchant account). Payment nodes let you set a prompt, confirmation message, and success/failure responses.
STEP 3 — DEPLOY TO YOUR SHORTCODE
Save your menu and click Deploy. The menu is immediately active on your registered shortcode — no code, no config files. Changes go live in seconds.
