Recently I needed to add a line to the Shopify Order Confirmation email that included the last 4 digits of the credit card used. This was more difficult than it needed to be, so I’m writing this post in hopes it’ll rise to the top in Google and help others trying to do the same thing.
TL;DR
You need to access the transaction object through a collection of transactions, like so:
{% for transaction in transactions %}
{{ transaction.payment_details.credit_card_number }}
{% endfor %}
This was stupidly difficult to track down. First, I went to the email variables article that’s referenced when you’re editing a notification. There, it states:
Notifications have access to every transaction property. Please see our Transaction API documentation here for a full list of the properties.
So I checked out that article, which didn’t help at all. Dead end.
After a few more searches, I finally found this thread in the forums that addressed my problem exactly. Reading through some of the comments, I thought I had hit another dead end, until I read the last comment in the thread, which pointed me to the thread that answered my question. Thanks to Mikkel Jakobsen for tracking down the answer!
