Hi @LuisReinoso looks like a good update will try it out in the coming days. Let me know if you have any issues with the CLA process.

Hi @forslund I didn't have problems with CLA.

Hi, your CLA has arrived and the code looks good. I've verified that the old user/pass system still works but for some reason my new apikey based instance doesn't work yet (not even using curl). Will give it some time to activate.

The code looks good and correct so I'll probably go ahead and merge this for the release if I can't my auth working.

Managed to get my creds working...and it's working fine now. Merging.
