In today’s fast-evolving industrial environment, API testing is essential for ensuring that
software applications and industrial systems communicate effectively and securely.
Whether you’re in software quality assurance, oil & gas pipeline inspection, or industrial
control systems, having the right API testing certification can boost your career and
credibility.

💡 What is API Testing?
API (Application Programming Interface) Testing is a process of verifying that APIs are
functional, secure, and reliable.
Unlike traditional GUI testing, API testing focuses on the business logic, data responses,
and performance of backend services.
Industries such as Oil & Gas, Manufacturing, and Industrial Automation increasingly depend
on integrated systems, making API testing critical for ensuring smooth operation.
