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.
By the end of this program, participants will be able to:
- Understand API, REST, and microservices fundamentals
- Interpret API specifications and documentation
- Design and execute API test cases using Postman
- Validate API responses, status codes, headers, and payloads
- Perform functional, integration, and regression testing of APIs
- Apply basic security, performance, and reliability testing concepts
- Support testing activities in microservices-based architectures
4 Days (9.00am – 5.00pm)
The duration and delivery schedule can be customized based on certification or client requirements.
- API Testers
- Software Test Engineers
- QA Engineers and Analysts
- Automation Testers expanding into API testing
- Developers involved in API validation
- Professionals working with REST APIs and microservices
