  config[:auth][:api_secret] = 'your-access-secret'
  config[:auth][:redirect_uri] = 'https://example.com/auth/constantcontact'
end

Documentation

Getting Started

AppConnect requires an OAuth access token which will give your app access to Constant Contact data and services for the accout that granted that access token.

Rails

Create a new controller action. The redirect_url should be the same as the one given when registering the app with Mashery. Use the following code snippet to get an access token:

@oauth = ConstantContact::Auth::OAuth2.new(
  :api_key => 'your api key',
  :api_secret => 'your secret key',
  :redirect_url => 'your redirect url' # the URL given when registering your app with Mashery.
)

@error = params[:error]
@user = params[:username]
@code = params[:code]

if @code.present?
  response = @oauth.get_access_token(@code)
  if response.present?
    token = response['access_token']
    cc = ConstantContact::Api.new('your api key', token)
    @contacts = cc.get_contacts()
  end
else
  # if not code param is provided redirect into the OAuth flow
  redirect_to @oauth.get_authorization_url and return
end

Create a view for the above mentioned action with the following code:

<% if @error %>
  <p><%= @error %></p>
<% end %>

<% if @contacts.present? %>
  <% @contacts.results.each do |contact| %>
    <p>Contact name: <%= "#{contact.first_name} #{contact.last_name}" %></p>
  <% end %>
<% end %>

The first time you access the action you will be redirected into the Constant Contact OAuth flow. Then you will be redirected back to your action and you should see the list of contacts.

Sinatra

Require AppConnect:

require 'constantcontact'

Add the following route. The redirect_url should be the same given when registering the app with Mashery.

get '/my_url' do
  @oauth = ConstantContact::Auth::OAuth2.new(
    :api_key => 'your api key',
    :api_secret => 'your secret key',
    :redirect_url => 'your redirect url'
  )

  @error = params[:error]
  @user = params[:username]
  @code = params[:code]

  if @code
    response = @oauth.get_access_token(@code)
    if response
      token = response['access_token']
      cc = ConstantContact::Api.new('your api key', token)
      @contacts = cc.get_contacts()
    end
  end

  erb :my_view
end

Create a my_view.erb with the following code:

<% if @error %>
  <p><%=@error%></p>
<% end %>

<% if @code %>
  <% if @contacts %>
    <% @contacts.results.each do |contact| %>
      <p>\Contact name: <%= "#{contact.first_name} #{contact.last_name}" %></p>
    <% end %>
  <% end %>
<% else %>
  <a href="<%=@oauth.get_authorization_url%>">Click to authorize</a>
<% end %>

The first time you access the action in browser you should see the "Click to authorize" link. Follow the link, go through all the Constant Contact steps required and then you will be redirected back to your action and you should see the list of contacts.
