This request returns a JSON body with a session token.

Lets go through an example which will illustrate this in more detail:įor this example, we’ll create and set a blank test environment. You can even add something dynamically generated through Javascript. All you have to do is call tEnvironmentVariable(key, value) or tGlobalVariable(key, value) to set a variable with values you have extracted from the response. Test scripts dramatically simplify this flow. This works, but is a lot of work if you have more than a few variables. Receive the response and select and copy a value from the response body or the header.The flow while working with variables currently goes like this: Some examples of common variables you would use with an API are session tokens and user IDs. Environment and global variables let you keep track of everything that affects the APIs state. One of them is extracting values from the response and saving it inside an environment or a global variable. This opens up a number of new possibilities. The pre-request and test scripts run inside a sandbox and Postman enable the Postman object to interact with the main Postman context. You can do practically anything in these scripts. Postman lets you write scripts that run before/after you receive a response from the server.
