Shopware 6 Plugin: Diagnose issues

Get the log files

When you submit a support request, either to Mollie support or through the Shopware 6 plugin store, plugin automatically attaches the log files. You can also access them through your Shopware 6 installation.

  • Open the var/log directory in your Shopware 6 installation. The Mollie log files have a mollie_ prefix.

Check status updates


You can customise the status mapping between Shopware 6 and Mollie.

  1. Check the Shopware 6 payment status.

  2. Check the Mollie status:

    1. Log in to your Mollie Dashboard.

    2. Go to Transactions > Payments.

    3. Search for the payment or order and check the status in the Status column.

  3. Compare the Shopware 6 and Mollie statuses to ensure that they correspond.

If the statuses don't match, try the troubleshooting options listed in Payments aren't processing properly.

Check Mollie webhook notifications

You can check whether the webhooks are working by comparing the update information in Shopware 6 with your Mollie Dashboard.


If you created an automated flow to tag Mollie webhooks, you can check whether they were successful in the Shopware 6 event logs↗.

  1. View the webhook notification in your Mollie Dashboard:

    1. Log in to your Mollie Dashboard.

    2. Find the order:

      • To find one-off product and initial subscription orders, go to Orders.

      • To find subscription instalments, go to Transactions > Payments.

    3. Click the order or payment and check the History column

      If the webhook notification was unsuccessful, try the troubleshooting steps in Payments aren't processing properly.

  2. If the order or payment webhook was successful, check the order in Shopware 6:

    1. Log in to Shopware 6.

    2. Go to icon-orders.png Orders > Overview.

    3. Click the icon-context-menu-button.png context menu button and select View.

    4. Go to Status and check the timestamps in the Payment status column.

      • Compare the timestamps with the webhook notifications in your Mollie Dashboard to ensure that they match.

      • Hover your mouse over the timestamp and check which system executed the update.

If the update was processed by a third-party or custom plugin, consult their troubleshooting documentation or contact their support team.
