Hi guys,

I’m trying to use the below code in Test

=====================================================

async function getExternalAccountId(account_id, i) {
    //Get the external_account_Id
    await pm.sendRequest({
        url: pm.environment.get("baseUrl") + '/restapi/v2.1/accounts/' + account_id,
        method: 'GET',
        header: {
            "User-Agent": "PostmanRuntime",
            "Connection": "keep-alive",
            "Authorization": "Bearer " + pm.environment.get("accessToken")
        },
    }, async function (err, res) {
        if (err) {
            console.log(err);
        } else {
            var jsonAccountData = res.json();
            var s = (i == 0) ? '' : ('_' + i);
            await postman.setEnvironmentVariable("externalAccountId" + s, jsonAccountData.externalAccountId);
            await console.log("External Account i = ",i);
        }
    }
    );
}

async function processResponseBody(responseBody) {
    var jsonData = JSON.parse(responseBody);
    var accounts = jsonData.accounts;
    if (jsonData.hasOwnProperty("sub")) {
        await postman.setEnvironmentVariable("userId", jsonData.sub);
    }


    for (var i = 0; i < accounts.length; i++) {
        if (accounts[i].is_default === true) {
            await postman.setEnvironmentVariable("accountId", accounts[i].account_id);

            await postman.setEnvironmentVariable("externalAccountId", '');
            //Get the external_account_Id
            await getExternalAccountId(accounts[i].account_id, 0);

            await postman.setEnvironmentVariable("accountId" + '_' + (i + 1), postman.getEnvironmentVariable('accountId'));

// The below line is for Question 2!!!
            await postman.setEnvironmentVariable("externalAccountId" + '_' + (i + 1), postman.getEnvironmentVariable('externalAccountId'));

            await console.log("in Default main i = ", i);


        } else {
            await postman.setEnvironmentVariable("accountId" + '_' + (i + 1), accounts[i].account_id);

            await postman.setEnvironmentVariable("externalAccountId" + '_' + (i + 1), '');
            await getExternalAccountId(accounts[i].account_id, i + 1);

            await console.log("main i = ", i);
        }
    }
}

// Main function

postman.clearEnvironmentVariable("userId");
postman.clearEnvironmentVariable("accountId");
postman.clearEnvironmentVariable("externalAccountId");

var i = 1;
while (pm.environment.has('accountId' + '_' + i)) {
    postman.clearEnvironmentVariable("accountId" + '_' + i);
    postman.clearEnvironmentVariable("externalAccountId" + '_' + i);
    i++
};

processResponseBody(responseBody);

=====================================================

The Console result is

GET https://account-d.docusign.com/oauth/userinfo
 
in Default main i = 0
main i = 1
main i = 2
 
GET https://demo.docusign.net/restapi/v2.1/accounts/XXXXXX
 
External Account i = 3
 
GET https://demo.docusign.net/restapi/v2.1/accounts/XXXXXX
 
External Account i = 2 
 
GET https://demo.docusign.net/restapi/v2.1/accounts/XXXXXX
 
External Account i = 0

Can you help me with 2 questions:

  1. Why await doesn’t help with the call orders?
  2. Why if I try to get the Environmental variable (see line above that commented for Question 2) it returned an empty value:

await postman.setEnvironmentVariable(“externalAccountId” + ‘_’ + (i + 1), postman.getEnvironmentVariable(‘externalAccountId’));

As a workaround I have to make the call getExternalAccountId again instead of the above line

await getExternalAccountId(accounts[i].account_id, i + 1);

Thanks

Hey there!

There’s a collection here that shows different way to write async tests:
https://www.postman.com/postman/workspace/postman-answers/documentation/3407886-220af2f6-63f2-4d84-903d-99e6e296a8c8?entity=&branch=&version=

You can fork it and try it for yourself, or copy/paste the code into your own collection. :slight_smile:
