Kulmi Pay is a payment platform built for African businesses. With a single API integration you can accept payments from customers, send money to mobile wallets and bank accounts, manage multi-currency balances, and receive real-time transaction notifications — all without stitching together multiple providers. Live operational coverage is currently focused on Kenya, with broader African expansion planned over time.

​
How Kulmi Pay works

Requests are authenticated with API keys from your dashboard. Use a public key for checkout and browser-safe collection flows, and use a secret key as a Bearer token for protected backend operations such as wallets, send money, and webhook management. Kulmi Pay notifies your server of transaction outcomes via webhooks, so your application can update records and trigger downstream actions without polling for status.
