PRC1007 – API United: Certified API, REST & Microservices Tester (CARMT) with Postman

Description

PRC1007 – API United: Certified API, REST & Microservices Tester (CARMT) with Postman

Overview

The Certified API, REST & Microservices Tester (CARMT) program is a professional certification designed to validate participants’ competency in testing APIs, RESTful services, and microservices-based systems using Postman. 

As modern applications increasingly rely on APIs and distributed architectures, this program equips participants with the knowledge and practical skills required to ensure API quality, reliability, and correctness. The certification emphasizes API fundamentals, REST architecture, microservices concepts, API test design, execution, validation, and best practices aligned with real-world industry expectations. 

Delivered through a certification-driven approach, the program combines standards, structured techniques, and hands-on practice to prepare participants for professional API testing roles.
