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

javascriptpostman

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.

var jsonData = JSON.parse(responseBody);
postman.setEnvironmentVariable("token", jsonData.access_token);

What I'm trying to do now is that run the Oauth request automatically (from a pre-request script) for any other requests which needs a bearer token.

Is there a way to get an access token and send an authenticated request with one postman button click?

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.
