How to run one request from another using Pre-request Script in Postman

Question

I\'m trying to send an authenticated request with one click in postman.

So, I have request named \"Oauth\" and I\'m using Tests to store the token in a local variable.

Answer 1

As mentioned by KBusc and inspired from those examples you can achieve your goal by setting a pre-request script like the following:

pm.sendRequest({
    url: pm.environment.get("token_url"),
    method: 'GET',
    header: {
        'Authorization': 'Basic xxxxxxxxxx==',
    }
}, function (err, res) {
    pm.environment.set("access_token", res.json().token);
});

Then you just reference {{access_token}} as any other environment variable.
