Fintech Test Platform
Sandbox environment for testing payment and lending integrations
Fintech Test Platform provides a fully isolated sandbox that mirrors production fintech APIs — payments, lending, KYC, card issuance, and open banking. Seed synthetic users, simulate edge cases (NSF, card declines, fraud flags), and run automated integration test suites before touching real money.

The Problem
Sound familiar?
Testing against live sandbox APIs costs real transaction fees and has unpredictable rate limits
Simulating edge cases (chargebacks, expired cards, fraud holds) is impossible in provider sandboxes
No shared team environment means every developer maintains their own test setup
The Solution
Fintech Test Platform fixes this.
Synthetic User & Account Generator
Generates realistic synthetic user profiles with FICO scores, transaction history, and KYC status — including edge cases like thin-file, fraud-flagged, and deceased.
Scenario Simulation Engine
Trigger specific scenarios via API: NSF declines, ACH returns (R01-R29), card network errors, KYC timeouts, and fraud holds with configurable delay injection.
API Mocking Layer
Intercepts calls to Stripe, Plaid, Marqeta, Alloy, and 15 other fintech APIs and returns deterministic mock responses so your test suite never hits a real endpoint.
How It Works
Set up in under 2 minutes. No complex configuration.

Automated Test Runner
Write test scripts in YAML or JavaScript. The runner executes flows end-to-end, asserts on outcomes, and generates a pass/fail report compatible with CI/CD pipelines.
Shared Team Sandbox
One environment for the whole engineering team. State is isolated per test run but shared fixture data (products, plans, users) stays consistent across developers.
Why not the alternatives?
Same result. A fraction of the price.
