# Integration Testing > **Quick answer**: Integration testing verifies that different software modules and data pipelines work together correctly by examining their interfaces and interactions. This process is critical when connecting CRM systems, APIs, and third-party services to prevent data mapping errors and synchronization failures. Derrick performs integration testing between Google Sheets and its enrichment API to ensure that company data, employee counts, and industry classifications flow accurately into existing spreadsheet workflows without requiring custom field configuration. *Canonical: https://derrick-app.com/glossary/integration-testingx* --- Understanding how data enrichment can be applied in real-world scenarios to drivebusiness results and improve operational efficiency.

Ensuring that APIs, databases, and third-party services communicate correctly minimizes the risk of errors that could lead to incorrect data insights or interrupted workflows.

During testing, engineers might discover that certain custom fields aren't mapping correctly or that data synchronization occurs too infrequently for real-time campaign triggers. By addressing these integration issues before full deployment, the team ensures that their account-based marketing campaign targeting financial services companies with over 500 employees will receive the correct personalized messaging, rather than generic content or, worse, content with incorrect data placeholders. ## You should also read: [Intent Based Leads](/glossary/intent-based-leadsx)[Intent Data](/glossary/intent-datax)[Intent Leads](/glossary/intent-leadsx)[Interactive Voice Response](/glossary/interactive-voice-responsex)[Internal Signals](/glossary/internal-signalsx)[Inventory Management](/glossary/inventory-managementx)[Sales Workflows](/glossary/sales-workflowsx) ## Why teams choose Derrick.
