The Rule engine is a powerful tool that makes it possible to adapt your Checkout configuration to your needs. Using the Rule engine you can set up conditions for most delivery options, services and addons to decide what alternatives to show in your checkout based on parameters such as weight, cart price, and destination.

This article will show you how to set up the following use cases:

• Price: If the cart contains items for EUR 50 or more the delivery is free of charge
• Weight: This delivery option should only be shown if the weight of the parcel is less than 20 kg
• Date range: Delivery is free from Christmas Eve to December 27th

Price

If the shopping cart contains items for EUR 50 or more the delivery is free of charge.

1. Go to Parameters in the sidebar menu and select cart_price from the drop-down list. Only activated parameters will be available for use in the Rule engine.
   
   
   
   
2. Next, go to Rule engine and click Add new rule.
   
   
   
   
3. Enter a name, e.g. "Free shipping". Activate the rule using the toggle switch in the top right corner.
   
   
4. Add the Conditions. In this example, the conditions say "if the cart price is greater than or equal to 50". 
   
   
   
   
5. Next, specify the Actions that should happen when the conditions are met. In this example, we set the price of the selected carrier service to 0.
