How to call Rest APIs URLS from service-now from client appliaction using Angularjs

[saran3]

I need a help about how to access service now tables to be accessed by inbound restapi url   to be   called at   C#.net based client application to retrieve,create,update and retrieve records using ANGULARJS.

        I have issue while accessing the REST URL for the table created on my service now instance and i tried to consume that URL to make call from .net client   application using angularJS for CRUD operation.it would be great that any one   made a call from client application to Service now before then kindly help me out to resolve this, where i had tried to made call from ay application it shows a error as "XMLHttpRequest cannot load http://xxxxx.service-now.com/api/now/table/<tablename>. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:55734' is therefore not allowed access." though i made recommended changes on request header as follows,which recommended for resolving this on many posts,

                            $http.defaults.headers.common['Access-Control-Allow-Origin'] = "*";

                      $http.defaults.headers.common['Access-Control-Allow-Headers'] = "X-Requested-With";

and also How to achieve or enable CORS(cross origin Resource sharing ),to make sure that client applications to access the rest apis without   an isssue.

Kindly help on this post....

You would need to use a Processor to be able to set your ServiceNow instance to support CORS (cross origin resource sharing). Within the processor you would need to create a custom API to gather the desired information.

Just a heads up, the REST API framework in SN will support CORS in a release coming very soon, so this use case will be supported in a better way.

Hi Saran,

If you follow the link in my previous post there is a link provided with an example on how to create an API within ServiceNow using a processor script.
