To build safely and test edge cases, you will start your integration in our Test (Sandbox) environment. Ensure your codebase points to the correct Base URL:

1. Test Environment (Sandbox): https://sandbox.monnify.com
2. Live Environment (Production): https://api.monnify.com

Developer Note: One of the most common errors is using Sandbox API Keys while pointing your code to the Live Base URL. Always double-check your environment variables.
