How do i link my gamertag to skate.ea?

Hi unbracings

This should be linked automatically unless you have used a different email address for your Gamertag and your Origin account. If so you will need to contact a Game Advisor to resolve the issue.

There is a sticky available for this situation where you can find more details and how to resolve it: Linking ea account to my gamer tag

I quoted the message:

Linking Your Gamertag, PSN ID, or EA Classic Screen Name

Your Gamertag/PSN ID, PSVita Online ID, and EA Account should be correctly linked when you first access an EA game online.
However, if the email address for your Gamertag/PSN/PSVita ID is different than the address for your Origin account, you will require assistance to properly link them.

This can be done by contacting an EA Game Advisor. Please include your Gamertag/PSN/PSVita ID and the e-mail address for your EA account.
