Retrieving list data from MailChimp using Ruby and gibbon

Question

I've created a test list in MailChimp and I added 2 subscribers.

I created a Ruby script that will retrieve emails of all subscribers with the help of gibbon gem.

The problem is that I'm the beginner in Ruby and I'm still really not confident with syntax.

Here's the code

require 'gibbon'
require 'byebug'

def mailchimp
  gibbon = Gibbon::Request.new(api_key:"my-api-key")
  gibbon.timeout = 10
  gibbon.lists("my_list_id").members.retrieve
end

debugger
mailchimp

When I test this in debugger with mailchimp.body, I can see that I get response, but it's in hash and with tons of information, while I only need to get email_address.

How can I dig or loop through this hash and only return email_address ?

Answer 1

You can restrict the request to only the fields you'd like to see. Only retrieve emails for fetched lists:

response = gibbon.lists("my_list_id").members.retrieve(params: {"fields": "members.email_address"})

With that response body you can call keys to see what fields are available to you. A little less noise than printing out the entire body in IRB.
