The initial value represents the default or starting value of the variable. It acts as a template that can be used as a reference throughout your API requests and collections.<\/p>\n<p>To set an initial value for a variable in Postman, you can use one of the following methods:<\/p>\n<p>1. **Pre-request Script:** You can use the pre-request script functionality in Postman to set an initial value for a variable. By using JavaScript code, you can assign a value to the variable before sending the request.<\/p>\n<p>2. **Global Variables:** Postman allows you to create global variables, which are accessible across all requests and collections within your workspace. Defining the initial value within a global variable ensures consistency and avoids redundancy.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Current_Value_in_Postman\"><\/span>Current Value in Postman<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>While the initial value refers to the default or starting value of a variable, the current value represents the value of the variable at a particular instance during the API workflow. The current value can change dynamically throughout the execution of requests and collections based on various conditions or actions.<\/p>\n<p>Postman enables you to modify the current value of a variable using different methods, including:<\/p>\n<p>1. **Tests:** You can update the value of a variable within the test scripts associated with a request. By manipulating the variable&#8217;s value during the test phase, you can perform validations or store data for future use.<\/p>\n<p>2. **Chained Requests:** Postman allows you to chain requests based on responses received. By extracting specific data from the response and assigning it to a variable, you can update the current value and use it in subsequent requests.<\/p>\n<p>It&#8217;s important to note that the initial value remains unchanged unless explicitly modified through the defined methods. This ensures that the variable retains its initial value unless it needs to be updated as part of the API workflow.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"1_What_are_the_benefits_of_using_variables_in_Postman\"><\/span>1.
