# Fully Simulated Testing Environment

Simulate use cases and try out platform features in the Dwolla Sandbox before releasing them to production.

## Supporting Your Payment Integration

Dwolla provides a fully simulated testing environment where developers and businesses can experiment, iterate and refine their payment integrations without incurring real-world risks.

### Validate Functionality

Create external parties, initiate transfers, attach test funding sources and test your webhook setup so you can take your solution to production with confidence.

### Isolated Environment

Increased load and activity in Sandbox doesn’t impact our production platform and API. Test without real consequences, and use fake data so real information isn’t exposed.

### Fully Simulated

Imitate production use cases, safely test your API calls and responses, and mock out low-volume and high-volume data in a controlled setting.

> “The API integration was seamless and the documentation explanations are in a language designed specifically for developers. It only took one developer to integrate the Dwolla Platform with our application.”  
> Transportation Company Chief Executive Officer

## Dwolla Connect

Dwolla Connect is a unified API solution across financial institutions and account-to-account payment methods and is designed specifically for mid- to enterprise-sized businesses with established payment operations. It empowers them to undergo a seamless digital transformation from outdated payment systems, manual processes, and file-based operations to fully streamlined, automated processes.

### Test every payment flow before a single dollar moves

Dwolla's sandbox replicates the full production environment: ACH, real-time rails, webhooks, returns, and edge cases. Build and test with confidence before going live.

## Key Benefits

### What changes for your team

Outcomes that matter to the teams responsible for payments, product delivery, and operations.

### Full Production Mirror

The sandbox replicates every API endpoint, webhook event, and payment flow available in production. What works in sandbox works in production.

### Simulate Edge Cases

Trigger returns, failures, timeouts, and specific error codes on demand. Test your exception handling before real money is involved.

### Instant Feedback

Sandbox payments settle immediately so your team can test full payment lifecycles in minutes instead of waiting for ACH windows.

### No Cost to Test

The sandbox is free and available immediately. Create an account and make your first API call in minutes.

## How It Works

### From integration to production

A clear path from first API call to live payment operations.

1. **Create your sandbox account**  
   Sign up at developers.dwolla.com and get API credentials immediately. No sales call required to start testing.

2. **Build and test your flows**  
   Use the sandbox to test payment initiation, webhooks, returns, mass pay, wallet operations, and any other flow your integration requires.

3. **Simulate real-world scenarios**  
   Trigger specific return codes, simulate network delays, and test error handling. Make sure your integration handles every scenario gracefully.
