The Nomba API operates within two distinct environments: the production environment (LIVE) and the sandbox environment. These environments serve different purposes and require specific credentials for interaction.

​
Base URLs

The base URL and credentials must always be paired to match the same environment. Using sandbox credentials with api.nomba.com, or production credentials with sandbox.nomba.com, will result in authentication errors.

Credentials

Production/Sandbox Keys

When you create an API key on the Nomba dashboard, both production and sandbox credential pairs (clientId + clientSecret) are generated at the same time. They are separate — sandbox credentials only work with the sandbox base URL, and production credentials only work with the production base URL.

​
Production

When using the production environment, your interactions directly affect the live system. Real transactions are processed and real money moves. Always use https://api.nomba.com with your production clientId and clientSecret.

​
Sandbox

The sandbox is an isolated environment for development and testing. Transactions do not affect your live account or move real funds.
Transactions conducted in the sandbox environment do not impact the production environment.
To make a sandbox API call, use https://sandbox.nomba.com with your test credentials from the dashboard. Here is a sample sandbox authentication request:
The sandbox returns simulated responses that mirror production behaviour. Data in the sandbox is isolated and does not appear on your live dashboard. See the Testing page for test card details and transaction scenarios.
