User Not Authenticated error when accessing the Rest table api.

[guptashalini041]

Hi,

I am getting below error when trying to access the Servicenow rest api.

401{"error":{"message":"User Not Authenticated","detail":"Required to provide Auth information"},"status":"failure"}

Below is the java script code by which I want to access the rest api.

<script type = "text/javascript">

function CallServicenow()
{

var requestBody = "";

var client=new XMLHttpRequest();
client.open("get","https://*****.service-now.com/api/now/table/incident?sysparm_limit=1");

client.setRequestHeader('Accept','application/json');
client.setRequestHeader('Content-Type','application/json');

//Eg. UserName="admin", Password="admin" for this code sample.
client.setRequestHeader('Authorization', 'Basic '+btoa('admin'+':'+'admin'));

client.onreadystatechange = function() {
 if(this.readyState == this.DONE) {
  document.getElementById("response").innerHTML=this.status + this.response;
 }
};
client.send(requestBody);

}
</script>

Below are the role assigned to this user.
admin
itil
personalize_dictionary
rest_api_explorer
rest_service
security_admin
snc_internal
web_service_admin

If I directly access the below url then it works. but not working when trying to access using script.

https://*****.service-now.com/api/now/table/incident?sysparm_limit=1

adding one thread here.. can you try this way.. just to validate if it's related to authentication issue or something else.

Hi Harshvardhan,

I tested it with Servicenow Script and it's working fine. But Java script and python script is not working and sending the below error :

401{"error":{"message":"User Not Authenticated","detail":"Required to provide Auth information"},"status":"failure"}

Any suggestion please..

thanks
