clients.each do |c|

Handling errors

If the createsend API returns an error, an exception will be thrown. For example, if you attempt to create a campaign and enter empty values for subject etc:

require 'createsend'

api_key = 'your_api_key'

begin
  cl = CreateSend::Client.new "4a397ccaaa55eb4e6aa1221e1e2d7122", api_key
  id = CreateSend::Campaign.create cl.client_id, "", "", "", "", "", "", "", [], [], api_key
  puts "New campaign ID: #{id}"
  rescue CreateSend::BadRequest => br
    puts "Bad request error: #{br}"
    puts "Error Code:    #{br.data.Code}"
    puts "Error Message: #{br.data.Message}"
  rescue Exception => e
    puts "Error: #{e}"
end

Results in:

Bad request error: The CreateSend API responded with the following error - 304: Campaign Subject Required
Error Code:    304
Error Message: Campaign Subject Required

Expected input and output

The best way of finding out the expected input and output of a particular method in a particular class is to use the unit tests as a reference.

For example, if you wanted to find out how to call the CreateSend::Subscriber.add method, you would look at the file test/subscriber_test.rb

should "add a subscriber with custom fields" do
  stub_post(@api_key, "subscribers/#{@list_id}.json", "add_subscriber.json")
  custom_fields = [ { :Key => 'website', :Value => 'http://example.com/' } ]
  email_address = CreateSend::Subscriber.add @list_id, "[email protected]", "Subscriber", custom_fields, true, api_key
  email_address.should == "[email protected]"
end
