Third-Party Validation Services
Third-party validation services are external tools or platforms that verify, authenticate, or check data, code, or systems for compliance, security, or quality standards. They are commonly used to validate inputs like email addresses, phone numbers, payment details, or API requests to ensure accuracy and prevent fraud or errors. These services offload validation logic from an application's core codebase, providing scalable and up-to-date checks.
Developers should use third-party validation services when building applications that require reliable, real-time validation of external data, such as e-commerce sites needing payment verification, user registration systems checking email deliverability, or APIs ensuring secure authentication. They reduce development time by leveraging specialized expertise, improve security by integrating fraud detection, and maintain compliance with regulations like GDPR or PCI-DSS without manual updates.
