Alter response in PostMan

Question

I'm using an open API.

But I am only using a small bit of data from the response the API provides. And as I'm testing using the API with different parameters to see the responses.

I don't want to see the entire API response every time I send the request, I only want to see the data that I'm interested in.

For example :

The response has 3 objects. Status, Features and Data. But I'm only interested in the Data object, I only want to see the Data object when making the request

Is there a way I can print a different Response, using the actual response of the Request?

Tests are run to validate data, and Pre-Request scripts are used to do something before the request, but I haven't found anything that changes the form of the Response.

There is no option to modify body but you can use the amazing visualizer feature in postman:

eg:

Set url and method:

    GET :  https://reqres.in/api/users?page=2

Add below code in test script:

template = `

        {{#each response}}
            
        {{/each}}
    
        
            Name
            Email
        

                {{first_name}}
                {{email}}
            
`;

// Set visualizer
pm.visualizer.set(template, {
    // Pass the response body parsed as JSON as `data`
    response: pm.response.json().data
});

Now click visualize:

You can see the visualize will show only first_name and email as a table .

You can use same logic in your case

If you want to print it as json itself then use below code in test script:

template = `
{{response}}
`;

console.log( JSON.stringify(pm.response.json().data, undefined, 2))
// Set visualizer
pm.visualizer.set(template, {
    // Pass the response body parsed as JSON as `data`
    response: JSON.stringify(pm.response.json().data, undefined, 2)
});

Output:
