Can you show us your javascript code and the errors you are getting. Workfront does not support JSONP, but they allegedly has an option that will enable CORS (Cross-Origin) in Setup -> System -> Preferences -> "Allow Embedding of Workfront in an iframe". From there you will need to also enable CORS on the server you are using to execute your API Code. It's probably best to just perform all API http requests from the server-side as is secure and standard and pass it back to the UI as json. Infrastructure wise, this would mean you may have an AJAX request from the UI of your website, this reaches out to your server and asks for Workfront data, your server sends API requests to Workfront and receives http responses, your server sends that response back to your client's UI, your client's UI parses the response text as JSON.
