Environments

To facilitate your API integration developments and tests, Mambu Payments offers distinct sandbox and production environments.

The sandbox environment is a safe playground. It is not connected to your partner banks and bank accounts and can be safely used to develop and test your integration. It is pre-loaded with sample data.

Production environments are connected to actual partner banks and clearing houses and can send and receive actual payments.

ℹ️
In sandbox, IP whitelisting is not available and mTLS is optional. This means customers can authenticate their requests using an API key as a single level of authentication. Learn more in Authentication.

⚠️
Using sandbox and production environments for load test or penetration test purposes is not authorised and might result in the suspension of your access.
