Take Armenian payments on Shopify.

  Paynet: Pay by card button for the Shopify order confirmation email.

  Where: Settings, Notifications, Customer notifications, Order confirmation,
  Edit code. Paste this anywhere below the order summary, then Save. Send a test
  notification from the same screen to see it.

  It shows only while the order is really unpaid, so a buyer who has already paid
  never sees it, and it leaves the email on its own once the order is paid. The
  store domain comes from Shopify, so the snippet is identical for every store:
  nothing in it needs editing.

  The two conditions are nested on purpose. Liquid has no parentheses and reads
  and/or right to left, so writing them on one line would be a trap for whoever
  edits this next.

  The text follows the buyer's own language. Shopify ships its default templates
  in many languages and sends each buyer their own, but the moment a template is
  customised it becomes monolingual, so the language has to be chosen here or an
  Armenian shop would email Armenian buyers in English.
