LinkedIn API get website-url from company

I am making requests to linkedinAPI to get companies information that the user is admin. At the moment is working the company name, id and locations. For others fields, linkedin returned to me the value null.

The company as all the information fulfilled. And I already tried with the company test (DevTestCo - 2414183) and gives me null.

My URL (without oauth2_code, but I am using it):

https://api.linkedin.com/v1/companies/2414183:(id,name,universal-name,website-url,locations,founded-year,company-type)?format=json

I am using this fields: https://developer.linkedin.com/docs/fields/company-profile

I think I'm doing okay, can anyone give me feedback?
