How to use variables and environments in Postman?
Postman also allows you to use variables and environments to store and reuse your headers and parameters. Variables are placeholders that can have different values depending on the context. Environments are sets of variables that can be switched depending on the scenario. You can use variables and environments to make your headers and parameters more dynamic, flexible, and manageable.
To use variables and environments, go to the Manage Environments button in the top right corner of the window and create a new environment. You can enter the name of the environment and the key and value pairs for the variables. For example, you might create an environment called Production and enter the variables base_url, auth_token, and content_type. You can then use the variables in your headers and parameters by using the syntax {{variable_name}}. For example, you might enter {{base_url}}/users as the URL, {{auth_token}} as the header value, and {{content_type}} as the parameter value. You can switch between different environments using the drop-down menu in the top right corner of the window.
Postman is a powerful and versatile tool for testing APIs with specific headers or parameters. By using Postman, you can set, send, receive, test, and reuse your headers and parameters with ease and efficiency. You can also use Postman to explore, document, and collaborate on your API projects.
