Using Local Variable In Post-Response Script's SendRequest Body

New to APIs/Postman

Hi all, not sure this is a Just Getting Started, but it is one of the first questions I have had that wasn’t pretty easily solved with a Google search.

I have an API call that returns an array object that I loop thru and pull out one piece of information that I need to pass into a subsequent POST request call. However, I cannot seem to figure out how to get that variable’s value correctly inserted into the Body I use on my post. Any assistance would be great! Thank you everyone!

You just call it by its variable name.

"ItemId": wltemid

You know… magic kinda loses its sparkle… its mysteriousness, when it is explained. Thank you! I do now see my variable’s value inside the body. How simple!

One further question, when I send this payload on the post request, the server rejects the body as bad format and all I can see when I copy the console for this is my body missing the double quotes. Feels like I am missing something maybe fundamental here. Thanks again.

I can’t tell from the image, you need to copy and paste as text using the preformatted text option in the editor.

However, I think you have the body incorrect. This is a working example with a JSON body.

const request = {
    url: 'https://postman-echo.com/post',
    method: 'POST',
    header: {
        'Content-Type': 'application/json',
    },
    body: {
        mode: 'raw',
        raw: JSON.stringify({ 'testKey': 'testValue' })
    }
};
