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. Your test data and actions do not impact real customer data or data from other institutions.
How to connect: When authenticating and sending requests, use the production endpoints:
Your institution will be set up in sandbox mode, so while the endpoints appear to be production, all activity is scoped to your isolated institution.
Credentials: You will receive sandbox-specific credentials for your isolated institution. Use these with the production endpoints as shown above. Credentials are delivered via SendSafely.
What runs automatically: The sandbox runs a daily allocation job, consistent with production behavior. Note that interest amounts may not reflect exact production rates.
Statements: Monthly statements are generated in the sandbox on the same cadence as production. Mid-month statements cannot be generated on demand. Sandbox statements do not include institution branding.
