Adding the integration code to Shopify Admin interface

DEPRECATION WARNING
Some Shopify APIs that affect the scripts in this section are no longer supported past April 1 2024. The barion.js and barion_v2.js scripts in this section have been updated to comply with the changes.

On the main admin page click Settings at the bottom of the left side menu, then select Checkout from the left side menu and add the following code to the section Additional scripts:
(Here you should already have the text added during Pixel installation)

IMPORTANT
The below steps will differ whether you create an Application for SANDBOX (see https://docs.barion.com/Sandbox) or PRODUCTION environments!

SANDBOX script:

<script src="https://shopify.test.barion.com/js/barion/barion.js"></script>
<script>Barion.init({
orderId: '{{ order.id }}',
domain: '{{shop.permanent_domain}}',
gateway: '{{order.transactions[0].gateway}}',
orderStatus: '{{order.financial_status}}',
sandboxMode: true
})</script>


PRODUCTION script:

<script src="https://shopify.barion.com/js/barion/barion.js"></script>
<script>Barion.init({
orderId: '{{ order.id }}',
domain: '{{shop.permanent_domain}}',
gateway: '{{order.transactions[0].gateway}}',
orderStatus: '{{order.financial_status}}'
})</script>


PRODUCTION script(alternative version):

If you experience issues with the redirection to the Barion Smart Gateway, you can use this code snippet instead of the production version above. It is important to place this script at the beginning of the Order status page section.

IMPORTANT
Be careful, this script uses reload on the Thank you page, so it can confuse your measuring.
<script src="https://shopify.barion.com/js/barion/barion_v2.js"></script>
<script>Barion.init({
orderId: '{{ order.id }}',
domain: '{{shop.permanent_domain}}',
gateway: '{{order.transactions[0].gateway}}',
orderStatus: '{{order.financial_status}}'
})</script>

TROUBLESHOOTING

Error messages and actions

The store is closed in the Barion system, payment is not allowed. In this case your Barion Shop is not approved yet. If the POSKey you used is for the right shop, you have to wait until it is approved.

Application not installed

  1.  The javascript code you pasted from here to the Shopify Checkout settings / Additional scripts field is most likely wrong. Keep in mind that the script is a bit different for the test/sandbox and for production.
  2. Order API rights were not set to read/write for the private app
  3. The plugin (shopify.barion.com) is set to a different domain than the shop itself (has to match the domain that is visible on the checkout page).
