def request_phase

  # We're doing this because the callback_url is built from the
  # options.name attribute which is built by down-casing the name of the
  # class. This returns an un-capitalized url which Rails will not
  # recognize as the same path as the devise controller. This is a forced
  # way to do this and probably has a more elegant solution.
  options.name = 'yourMembershipToken'
  # Build an Access Token
  session = YourMembership::Session.create
  token_hash = session.createToken(:RetUrl => callback_url)

  # Store the YourMembership session id somewhere it can be retrieved
  # during the callback_phase.
  #
  # In OmniAuth 1, we were able to do:
  #
  #     request.params['ym_session'] = session.to_s
  #
  # but this seems no longer possible in OmniAuth 2 (as described in
  # https://github.com/omniauth/omniauth/issues/975). So, the only thing I
  # can think of is to use `env['rack.session']`. If a better solution
  # is discovered, we can revisit this decision.
  env['rack.session'][RACK_SESSION_KEY] = session.to_s

  # Redirect to token url
  redirect token_hash['GoToUrl']
