Business rule and REST

argho · ‎08-03-2017

Hi there,

I am very new to Service NOW. I was trying to accomplish that every time an incident is created, I send a REST post request to an external server. I tried to follow the guide https://express.servicenow.com/support/videos/servicenow-express-outbound-rest/

So I have my outbound rest call defined and tested and that works fine:

But once I try to create a business rule ( I do this as the admin user), something weird happens, the web tab appears but shortly after the page has loaded the tab disappears...

When opening the page:

After loading is completed:

So then I tried with the Advanced option and added the code I retrieved from the outbound section, it looks like this:

try {

var r = new sn_ws.RESTMessageV2('Change record', 'UPDATE EXTERNALLY');

r.setStringParameterNoEscape('close_date', current.resolved_at);

r.setStringParameterNoEscape('INCIDENT_NUMBER', current.number);

r.setStringParameterNoEscape('inc_id', current.number);

//override authentication profile

//authentication type ='basic'/ 'oauth2'

//r.setAuthentication(authentication type, profile name);

var response = r.execute();

var responseBody = response.getBody();

var httpStatus = response.getStatusCode();

}

catch(ex) {

var message = ex.getMessage();

}

However, nothing happens... I was monitoring my server, but no calls are received there either... Am I missing something all too obvious?

thanks!

Kind regards!

You need to set the REST Type.

var r = new sn_ws.RESTMessageV2('Change record', 'POST'); // POST or GET based on what you need.

If that doesn't work, you can try something like below.

var method = "post";

var endpoint = 'https://www.your_endpoint_'

   var rm = new sn_ws.RESTMessageV2();

   rm.setHttpMethod(method);

   rm.setEndpoint(endpoint);

   var body = { some JSON stuff };

   rm.setRequestHeader("Content-type", "application/json");

   rm.setRequestBody(body);

   var response = rm.execute();

   var responseBody = new JSON().decode(response.getBody());

Hope this helps. Mark the answer as correct/helpful based on impact.

Thanks

Hi AA,

The link your have referred to

https://express.servicenow.com/support/videos/servicenow-express-outbound-rest/

has guidance on how you create outbound REST on the Express platform, this platform does not support scripting

https://express.servicenow.com/support/forums/topic/service-now-express-differences/

Your screenshots indicate you are implementing on Enterprise product so you should check out the Enterprise documentation.

This link, which includes a video, would be a good starting point.
