Update record in ServiceNow by passing JSON object in the URL

Question

I am trying to update a record in a ServiceNow instance (running Calgary) using the JSON Web Service, but unfortunately it is not happening.

I am able to insert the record but the update operation doesn't happen.

The call in the Developer tools of chrome (Network section) looks good (could see the url and JSON object bound with data)

Here's the code snippet with the URL I'm testing:

var url = 'https://<instance name>.service-now.com/u_test_employee.do?JSON&sysparm_query=u_number=EMP0001102&‌​sysparm_action=update'
var responsePromise = $http.post(url, dataObj, {}); 

Any ideas or suggestion is appreciated.

Answer 1

Probable cause for failure of update operation might be missing ACLs. The table which you are trying to update need to have table level write ACL otherwise by default no write (update) operations are allowed
