New Looker API

[sri75]

What would be the new URL for the updated Looker API

I am still using the same as before but it doesn't work for me anymore? I am very sure an updated API wouldn't change anything with this part but i want to confirm. The url works if i use the 443 port and takes me to the login page but the port 19999 doesn't work anymore. 

https://lookerinstance,companyname.com:19999

I sometimes get a 502 error or a 400 error using the same url as above. If I’m using this with older version environments it works just fine and gives me the message 

auth required and refer to the docs.looker.com
