Test and verify reports

​

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.
