The often overlooked feature of environment variables in Postman significantly expedites the development process. Consider a scenario where we are simultaneously working on multiple projects, and we decide to switch the port number for one project from 3000 to 3001. In Postman, we may have configured the URL with the old port (3000) in numerous requests. If we had utilized environment variables for the URL, this would have streamlined the process. Changing the port in one central place — the environment variable — would automatically update all instances across various requests.

Moreover, environment variables in Postman allow us to create distinct environments for different stages, such as development and production. This flexibility eliminates the need to maintain separate collections for local development and production environments. By adjusting the base URLs in the corresponding environments, we ensure consistency across all requests. In essence, leveraging environment variables not only enhances efficiency but also promotes better organization and maintenance of Postman collections.

Additionally, this process can be extended to automate the capture of JWT tokens from responses. By incorporating environment variables, we can seamlessly reference the captured token in the headers of subsequent requests. This eliminates the manual and error-prone task of copying…
