I’m developing a Shopify app that allows you to complete certain product information from an external app.
I have one last step left: managing the email confirmation.
When the end user pays for a product and the payment is accepted, they will receive a confirmation email from Shopify.
What I’d like is to be able to add a small HTML block with a link and a short text at the beginning or end of this email.
But I’m a little lost on how to do this. Do you know how I can inject a piece of HTML code into the Shopify confirmation email?
