Postman

Postman is a collaboration platform designed for developing and testing application programming interfaces (APIs). It serves as a hypertext transfer protocol (HTTP) client that allows users to test HTTP requests and receive various types of responses through an intuitive graphical user interface. Postman simplifies interactions with Fast Healthcare Interoperability Resources® (FHIR®) servers, enabling users to post requests and updates efficiently. It is particularly useful for testing FHIR-based electronic clinical quality measures during Health Level Seven International® Connectathons.
