Physique
The physique of a request is the place you ship information to the server, significantly in POST, PUT, and PATCH requests. The physique can take varied codecs, resembling JSON (JavaScript Object Notation) and XML (Extensible Markup Language). JSON is the most typical format for contemporary APIs. Postman permits you to assemble request our bodies utilizing uncooked enter (plain textual content), kind information, and different codecs.
Authentication
Authentication is essential for safe API interactions. Postman helps a number of authentication mechanisms, together with fundamental authentication (username and password), API keys (distinctive identifiers), OAuth (a delegated authorization protocol), and Bearer tokens (generally utilized in trendy APIs).
Variables
Variables are a robust characteristic that permits you to retailer and reuse values inside Postman. They’re particularly helpful for managing environment-specific configurations, resembling completely different API endpoints for improvement, staging, and manufacturing. Utilizing variables eliminates the necessity to hardcode values and reduces the danger of errors.
