Postman pm.sendRequest example

example.md

To send a request via the sandbox, you can use pm.sendRequest.

pm.test("Status code is 200", function () {
    pm.sendRequest('https://postman-echo.com/get', function (err, res) {
        pm.expect(err).to.not.be.ok;
        pm.expect(res).to.have.property('code', 200);
        pm.expect(res).to.have.property('status', 'OK');
    });
});

Without additional options, this will sent a GET request to the URL specified. If you prefer to be more explicit, you can use the complete syntax:

pm.sendRequest({
    url: 'https://postman-echo.com/post',
    method: 'POST',
    header: 'headername1:value1',
    body: {
        mode: 'raw',
        raw: JSON.stringify({ key: "this is json" })
    }
}, function (err, res) {
    console.log(res);
});

Hi,
I have a situation where I need to make a REST call from inside the "Tests" tab.

var jsonData = pm.response.json();

async function getApp(uuid) {
    console.log(uuid);
    pm.sendRequest({
        url: pm.environment.get(base_url)+'/api-management/1.0/applications/'+uuid,
        method: 'GET',
        header: {
            'Accept': 'application/json',
            'Authorization': pm.environment.get("accessToken")
        }
    }, function (err, res) {
        console.log(res.json());
    });
}

pm.test("APPs", function () {
    _.each(jsonData.results, (item) => {
        var name = item.name.toLowerCase().replace(/\s/g, "_");
        pm.environment.set("app_"+name+"_uuid", item.uuid);
        getApp(item.uuid);
    })
});

So, within pm.test I am calling another function called "getApp", that's making a pm.sendRequest call.
For some reason that pm.sendRequest is not getting executed. Note the console.log(uuid) is getting printed fine.
Can you please help identify the issue?

@arun-a-nayagam I have seen stuff like that happen because the "pm.test" block finishes executing before the rest call is completed... I haven't found any other way to solve that but using setTimeout... I would try putting a timeout probably in the getApp call

setTimeout(() => { getApp(item.uuid ) },2000)

And see what that does... or maybe around the whole pm.test

setTimeout(() => {
pm.test("Apps", function () {
...
})
) },2000)

EDIT: I came back here because for some reason your issue kept revolving inside my head, and found a few things I think need to be pointed out

1. Why are you setting up the environment variable inside the pm.test block? I mean, the pm.test block is intended for testing your request's response...
2. Why is it that you are not asserting anything in your test?
3. How exactly are you trying to detect that the sendrequest has been executed? By checking if the console.log prints correctly?

Hi,
@jprealini Thank you for the reply. Apologies, I did find what my issue was but I forgot to come and update here.
Basically, I had to surround my pm.sendRequest around a try, catch block.
If it's not surrounded then it was not writing to the console of an issue with the sendRequest.

And about your questions,

1. In this instance I don't use the Test block for asserting a test case.
   My intention is to run a script after a postman request to initialize my env vars which I will subsequently use in other API calls.
2. See 1
3. Yes, I was expecting the console.log to indicate what the response was.
   But as I said there was an issue with the call and without try/catch there was no information shown in the console.

I really appreciate you replying back and checking! Thank you.

Is there any way to run a saved request from the collection in the Pre-request Script?

like postman.setNextRequest('req-name') but before the actual request not after.

Is there any way to run a saved request from the collection in the Pre-request Script?

Not that I'm aware of. I've recently asked them for this feature, though. It would be a huge timesaver if we could just pm.sendRequest by GUID.

any update on this? @ABlomberg
