Why can Gibbon Gem access API but can't listSubscribe()?

Question

I'm trying to get mailchimp integrated with my ruby-on-rails app using the Gibbon gem.

I've successfully accessed the API. I tested it by getting a list of all my mailchimp lists. However, I'm running into problems with the listsubscribe method. I'm not getting any errors, it just isn't working at all.

I have the following code in the controller for the page where users sign up, after the user is made and their information can be accessed.

gb=Gibbon::API.new
gb.listSubscribe({:id => "the-id-for-list", :email_address => user.email, :update_existing => false, :double_optin => false, :send_welcome => true, :merge_vars => {'FNAME' => user.first_name, 'LNAME' => user.last_name, 'MERGE3' => user.subscription, 'MERGE4' => DateTime.now}})

It does nothing. I've tried playing around with the parameter phrasing (à la this post:How do you use the Gibbon Gem to automatically add subscribers to specific interest groups in MailChimp?) I've tried structuring it more like in this tutorial: http://www.leorodriguez.me/2011/08/subscribe-member-into-mailchimp-using.html

I have no idea what's going wrong. As I said before, other API calls are going through to MailChimp. Do you have any suggestions? Thank you in advance.

Answer 1

It turns out I had the code in the wrong place. I was not putting it where users were actually being created, but in the code to generate the view to ask users to sign up. Once I moved it to where the user was actually created, it worked fine.
