# Test and verify reports

Thorough testing ensures your reporting integration works correctly before going live. PayPal provides sandbox environments and verification tools to validate your implementation.

## Prerequisites

* Sandbox PayPal Developer account.
* Test API credentials.
* Understanding of expected data formats.
* Verification checklist.

## Steps for testing

### 1. Sandbox environment setup

* Create sandbox business account.
* Generate test API credentials.
* Configure sandbox endpoints.
* Create test transactions.

### 2. API endpoint testing

```javascript theme={null}
// Test with sandbox endpoint
const SANDBOX_BASE_URL = 'https://api-m.sandbox.paypal.com';

const testTransactionSearch = async () => {
  try {
    const response = await fetch(`${SANDBOX_BASE_URL}/v1/reporting/transactions`, {
      headers: {
        'Authorization': `Bearer ${sandboxAccessToken}`,
        'Content-Type': 'application/json'
      }
    });
    
    console.log('Test successful:', await response.json());
  } catch (error) {
    console.error('Test failed:', error);
  }
};
```

### 3. Data validation testing

* Verify transaction data completeness.
* Check date range filtering.
* Test pagination functionality.
* Validate response formats.

### 4. Error handling verification

* Test invalid credentials.
* Check rate limit responses.
* Verify timeout handling.
* Test malformed requests.

## Using webhooks events dashboard

### Access event details

1. Navigate to PayPal Developer Dashboard.
2. Select "Webhooks Events" section.
3. View event status and details.
4. Use resend functionality for testing.

### Webhook verification testing

* Test webhook endpoint reception.
* Verify signature validation.
* Check event processing logic.
* Test retry mechanisms.

## Samples

```javascript theme={null}
// Comprehensive test function
const runReportingTests = async () => {
  const tests = [
    testAuthentication,
    testTransactionSearch,
    testDateFiltering,
    testPagination,
    testErrorHandling
  ];
  
  for (const test of tests) {
    await test();
  }
};
```

## Testing checklist

* Authentication works correctly.
* API responses are properly parsed.
* Date filtering functions as expected.
* Pagination handles all scenarios.
* Error responses are handled gracefully.
* Webhook events are received and processed.

## Best practices

* Test with realistic data volumes.
* Verify all error scenarios.
* Use automated testing where possible.
* Document test results and fixes.
