Need help calling REST API

Need help calling REST API

  
I'm trying to call into our MobileIron Web Services REST API and I can't figure out how to do it. Our admin needed to give me access to the API via network username and password, and I can make calls using the URLs in a browser. How do I do this in Outsystems?

Example URL: https://vsp.cablevision.com/api/v1/dm/devices

I tried to use GetRequest_Submit using the URL but I keep getting a 404 error. How do I specifiy the username and password?
Thanks,
Gerry
404 means the URL is not found (valid in the API?).

When you do have an authentication error you usually get a 403 error (Unauthorized). Are you sure the URL you are asking for is valid in the API you're accessing?

 I can type the same URL into a browser - it'll ask for username and password, and then send back a proper reply.
