Google Identity Toolkit with go Step 1

I want to use Google Identity Toolkit with a web.go backend. GIT tutorial says I need some handlers, so here we go:

    web.Post("/gituserstatus", gitUserstatusHandler)
    web.Post("/gitlogin", gitLoginHandler)
    web.Post("/gitcallback", gitCallbackHandler)
    web.Get("/gitcallback", gitCallbackHandler)
    web.Get("/fbcallback", fbCallbackHandler)
    web.Get("/gitsignup", makeUserTemplateHandler("signup"))
    web.Get("/githome", makeUserTemplateHandler("home"))
