Doesn't Google Webmaster Tools v2.0 API work anymore?

Question

I'm trying to edit Google Webmasters site settings (set targeting country), but as far as I know v3 doesn't allow to do this, so I'm using v2.

However, I get 401 Unauthorized response for all the Webmaster Tools v2 endpoints. Here are steps I have performed:

• Visit Google OAuth 2.0 Playground
• Picked Webmaster tools v2
  
  
• Authorized this API and exchanged authorization code for tokens. (After that I got a message "The access token will expire in 3599 seconds.")
• Then hit "List possible operations" and chosen "List sites"
  
  
• Finally, clicked "Send the request" and got 401
  
  

I did it several times I all the time I got the same result.

What is the reason of such behavior? Is Google Webmaster Tools v2 deprecated?

Answer 1

Yes its deprecated. I cant find an official deprecation but all the documentation on V2 just links to v3. Which is probably why I cant find the official deprecation date. Google normally gives you a year to move once they deprecate something.

I found a comment from Google dated 11/20/15 stating

Version 2 is on it's way to be completely deprecated, so I would move away from it. Whatever still works and breaks, likely will not be fixed.

Time to move to v3
