API Call from javascript node in workflow

[Ramaswami]

Hi guys, 

i am trying to call an API from javascript node in a workflow llike below : 

var http = new HttpClientRequest("https://xxxxx/accesstoken")

var buffer = new MemoryBuffer()
buffer.fromString("abc" + ':' + "efg", "iso-8859-1")
http.header["Content-Type"] = "application/x-www-form-urlencoded"
http.header["Authorization"] = "Basic " + buffer.toBase64()
http.body = "grant_type=password&username=conny.roscher@dynata.com&password=PaneL321!@"
http.method = "GET"

http.execute()

var result = http.response.body.toString();
logInfo("Results = " + result)

i am getting the below error : 

JST-310026 The URL 'https://api.trustpilot.com/v1/oauth/oauth-business-users-for-applications/accesstoken' that the script is trying to access is not part of the authorized addresses in urlPermission (serverconf.xml)

i saw in other posts that we need to whitelist so i went to control panel and added this url under instances>URL permissions but still the same error.

i saw in one other post to add in destination url : 

https://experienceleaguecommunities.adobe.com/t5/adobe-campaign-standard/how-to-perform-an-api-rest-...

but this is not clear. where should i add my url inorder to overcome this error. can you please eloborate

Thanks @david, it worked but after this when i run the script i am getting the below error :

Results = {"reason":"Unknown grant_type"}

HTTP header 'WWW-Authenticate' used for proxy authentication not found.

script : 

var http = new HttpClientRequest("https://api.trustpilot.com/v1/oauth/oauth-business-users-for-applications/accesstoken")

var buffer = new MemoryBuffer()
buffer.fromString("hrIrJQO0rKQdWSf" + ':' + "AK4ceo", "iso-8859-1");
http.header["Content-Type"] = "application/x-www-form-urlencoded";
http.header["Authorization"] = "Basic " + buffer.toBase64();
http.header["grant_type"] = "password";
http.header["username"] = "abc.com;
http.header["password"] = "PaneL321!@";
http.body = "grant_type=password&username=abc.com&password=PanesddL321!@";
http.method = "GET"

http.execute()

var result = http.response.body.toString();
logInfo("Results = " + result)

you may need to review the api documentation of TrustPilot. the error stands that grant_type (password here) is unknown

It looks like to obtain a token you need your API Key, API Secret, Trustpilot username and password.

Thanks,

David
