Environment variables in Postman are a powerful feature that allows you to store and reuse values across multiple requests. This can be especially useful when you’re working with different environments like development, testing, and production. By using environment variables, you can easily switch between these environments without changing each request manually. In this article, we’ll explore three practical examples of setting up environment variables in Postman that will help streamline your API testing.
When testing APIs, it’s common to have different base URLs for various environments (e.g., development, staging, production). Instead of hardcoding these URLs into every request, you can use an environment variable to manage them more efficiently.
baseUrl and set its initial value to https://dev.api.example.com.{{baseUrl}}. For example, instead of https://dev.api.example.com/users, use {{baseUrl}}/users.You can create additional environments for staging and production, setting the baseUrl variable accordingly. Switching environments will automatically change the base URL used in your requests.
When working with APIs that require authentication, managing tokens can become cumbersome. Using an environment variable to store your authentication token simplifies this process.
