Drupal MailChimp Ecommerce Recover Abandoned Cart

Question

I am trying to integrate MailChimp to my Drupal 7 site. But I am facing some problems right now.

What I can do:

• I can subscribe new users to my MailChimp list.
• I can send order data to MailChimp when a customer completes their purchase.
• I can send Welcome Message campaign email.
• I can send First Purchase campaign email.
• I can send follow up mails for these campaign mails (for example; send mail after 1 hour if a subscriber receives First Purhcase email).

What I can not do:

• I can not send Abandoned Cart campaign emails.
• I can not show product info on ecommerce mails.
• I can not see Cart data when I make a POST request to usX.api.mailchimp.com/3.0/ecommerce/stores/{store_id}/carts

I would like to give more info if needed.
edit: fixed grammar
edit: I can see Cart data when I make a POST request to usX.api.mailchimp.com/3.0/ecommerce/stores/{store_id}/carts. To achieve that, I have just deleted cart data in my Drupal 7 commerce website. So it kind of worked like a soft restart.

Answer 1

I have found the issue and fixed it.

For future readers;

The issue was that, MailChimp eCommerce module is not sending the checkout_url(path to the cart) out of the box. Although it is not required to sent checkout_url while POSTing, it is mandatory if you want to use Abandoned Cart email. In order to fix that problem, there are two patches that needs to applied.
Patch #1
Patch #2
