Using the Sandbox


ModernFi provides a sandbox environment for safely testing the public API. The sandbox is designed to mimic production while keeping your test data isolated from live financial data.

How it works:

  • The sandbox runs on the same production-grade infrastructure as our live environment but uses a separate, isolated institution dedicated to your testing.
  • This means that your test data and actions do not impact real customer data or data from other institutions.

How to connect: When authenticating and sending requests, you will still use the production endpoints:

auth.modernfi.com
api.modernfi.com

Your institution will be set up in sandbox mode, so while the endpoints appear to be in production, all activity is scoped to your isolated institution.

Credentials:

  • You will receive sandbox-specific credentials for your isolated institution.
  • Use these credentials with the production endpoints as shown above.

This setup provides the realistic behavior of production while keeping your data entirely separate for testing purposes.
