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

// 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

// 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.
