If Mollie can’t send a webhook, Mollie for Salesforce runs the
Mollie-FailExpiredOrders job to retrieve status updates. The job requests updates for orders with the Created status from Mollie. It also updates the orders accordingly.
Ensure that the job's flow scope↗ includes your storefront site.
Configure the job's waiting time and automatic starts under Administration > Operations > Jobs > Mollie-FailExpiredOrders > Job steps > FailExpiredOrders.
