OAuth - how to get the e-mail and URL pages of the Odnoklassniki user?

Question

Email

When registering on the site, I use OAuth from three social networks: VKontakte, Facebook and Odnoklassniki. From the first two networks I receive: the user's URL page (which is then shown on the site by a link in the user's profile) + I combine them into one user profile using the incoming E-MAIL, which most have one everywhere in networks. But with Odnoklassniki there is a snag, I read the API, looked at the lists of incoming variables there ... It does not return either the URL or the E-mail. Actually, as a result, a new account is created for the user who came with OK, even if he already has one from VK and Facebook. Is it even possible to somehow get an e-mail or, at least, the user's URL page (the second one is definitely not secret information).
