Shopify Payment App – Migration

With an update to our Shopify integration comes changes to how the solution is configured. Previously, you used a Pay Now ID and passkey to enable POLi payments. Now you will need to use your Merchant Code and Authentication Code. While you haven’t been provided this initially, we have made it easy for you to find this information.

If you do not have your Merchant and Authentication code, click here for a guide on how to find these.

To configure your Shopify store to accept POLi payments, please follow the steps below.

  2. Click ‘Payments’ from your store settings menu.
  3. Scroll to the Supported payment methods section and click ‘Add payment methods’.

  6. Click ‘Activate’
  7. Click ‘Connect’.
  8. You should be taken to a configuration page.

    You may also configure your Particulars/Code/Reference bank fields for reconciliation.
  9. Once your details have been saved click ‘Back to Shopify’.
  10. Ensure that the POLi method is ticked then click ‘Activate POLi – NZ’.
