Here, we have added the variable u and the value as. Step 2 − MANAGE ENVIRONMENTS pop-up gets opened. Step 1 − Navigate to the New menu and then click on Environment. Create Environmentįollow the steps given below to create an environment in Postman − Each of these environments will have different parameters like URL, password, and so on. We can create environments for production, testing and development. In short, an environment allows the execution of requests and collections in a varied data set. However, we can work with a single environment at one time. There can be multiple environments and each of them can also have multiple variables. The key in the key−value pair in the environment is known as the Environment variable. As we create environments, we can modify key-value pairs and that will produce varied responses from the same request. It helps to identify each request separately. In Postman, an environment consists of a key-value pair. Thus, the variables help to minimise the chance of errors and increase efficiency. If we need to modify a value, we need to do it in only one place. It means, that the global variable is in action and is working the same for different environments.Variables give the option to hold and repeat parameters in the requests, collections, scripts and so on. In both cases, I have got the same response. Secondly, I select a different environment called: new-environment. First, I shall select the environment myenv. Let us select any environment and send the request. Now, select any environment of your choice( does not matter which one you choose), the request will work for all the environment. Now, go to the URL bar of the request and use the variable cvalue in place of and then append the request end-point. I shall Select the List User, which is GET type, and copy the request end-point. Now, create any request which requires the URL part- And then append the required end-point and send the request.įor example, I shall visit the link: and then select a GET request. I shall create a variable for the URL part- and will name the variable as cvalue(which I indicate the common value, as this URL part is going to be used in different requests, you can use any name you want). Then you will get an area to create global variables and set value for them. To create Global variables, go to Manage Environment and click Globals. But all the request contains a part of the URL which is common to all. Global Variables are used when we create different environments with different requests inside them. But it is also possible to set variables globally, where the variable can be used in any of the environments. However, when variables are set at the environment level, then the variable can only be used when the request is within the environment. In the previous section we have seen how can we set an environment variable and when the request has to be run, we select the required environment and then send the request to get the response. So, we have seen that how we can set variables in the environment, and still the URL runs a similar way. Now, the request should work well and the response should be visible below in the software. In our case, the variable is the url and the syntax contains variable between a pair of braces in the URL.Īnd then select the Environment as a new-environment. And then select the Update button.Īfter you have named and updated your variable, go to the URL bar and replace the part of the URL with the variable you declared. To do so, click on the Variables tab and then provide a name to the key(url) and then edit Initial and Current value. Therefore, we shall try to store this part of the URL in a variable, and try substituting it inside the POSTMAN software and see whether it works. You can see that the URL part is common to both the above URLs. Now, copy the first part of the URL which is common to both of the requests. Now, click on the variable tab and you will be asked to enter the key, which is the variable name(anything you want). Select Edit from the list.Īfter you select Edit, you should see as below: To open the variable section and click the three dots beside the collection name, and then a dropdown list will appear. Therefore, the first part can be stored in a variable so that, the variable can be used when the website URL is required. Two requests which are inside the collection- Collection01 have the first website link in common just the request end-points are different. In this section, we shall learn about creating a variable, use a variable, and refer a variable. Also, this technique can very helpful when you want to make changes to the URL. Using this concept of storing a part of the URL in a variable and using it in multiple places can save the time of typing a lengthy URL. Variables are used to store a value in POSTMAN most of the time we will store part of the URL in a variable.
