Check Mollie webhook notifications


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 a webhook notification states that a webhook was unsuccessful, check whether payments are processing properly.

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