Hi, I am trying to call the third party application using script in service now workflow.When someone request a item from service now catalog It goes for approval to admin.Once admin approves the request incident status is approved.But before ending the workflow I want to run script to call some third party application API and do some task using script. My first question is : is this possible to call third party app from workflow script? Second Question : can someone please guide me how to call third party app if possible? Thanks, Vimal Mishra

Hi,

First : Yeah it's possible to call third party application.

Second: To call third party application you   must have knowledge of SOAP or REST web services. For this u have to write a SOAP or REST script in 'script action' and   create a event, attach your script action to the even and you can call that event in the workflow.

For more info about Web service, Please go thought Web Services - ServiceNow Wiki .

If it's helpful,   please mark as correct or helpful.

Thanks,

Hi Veeresh,

Thanks for the reply.

I am using ruing Run Script from the utilities section to make call to third party application.I am very new to this so I don't know how to write script in that,Please find following script that I have added :

var r = new RESTMessageScripted("get","http://<hostname>/auth/signin");

r.addHeader("Content-Type","application/json");

r.addHeader("Accept","application/json");

r.setBasicAuth("username","passowrd");

var response = r.execute();

gs.log(response.getBody());

I am getting following error whwn I run the script:

Caught exception in InterpretedScript <refname>: org.mozilla.javascript.JavaScriptException: ReferenceError: "RESTMessageScripted" is not defined.

(#0(eval); line 1)

Thanks,

Hi Vimal,

Yes, you can definitely call third party app from workflow script.

If you are trying to call this third party app using a rest web service, then you can create a "Rest Message" in workflow to complete your request.

Else you can let me know as how do you want to call your third party application from workflow?

Thanks and Regards,
