Rules engine

Shipping rules change quotes when a condition matches: add or subtract an amount, set a fixed price, offer free shipping, or hide a quote. Package-type rules choose the package type for items by weight range. Both are edited in the Transdirect members area, on your Shopify store’s module page.

Where to edit rules

In Shopify admin, open Apps > Transdirect Shipping.
On the Dashboard, click the Postcode rules engine card (shipping rules) or the Package-type rules card. Your module page opens in the members area in a new tab. Sign in if prompted.
Shipping rules are on the Shipping rules tab, in the Rules panel. Package-type rules are on the Packaging tab, in the Package Type Rule panel.

You can also go to Settings > Integrations in the members area and click Settings on your Shopify store’s row.

Shipping rules

Each rule has a Trigger, a Value to match, a Priority, an Action and an Action value. Click Add rule to save it.

Trigger	Matches
Postcode	The delivery address. In List mode, enter postcode and suburb pairs separated by commas, such as `2000 SYDNEY, 2010 SURRY HILLS`; a postcode on its own does not match. In Range mode, enter the first and last postcode separated by a comma, such as `0800, 0899`.
State	The delivery state as a capitalised abbreviation, such as `VIC`.
Weight	The total weight in kg of what is quoted, compared with Equals, Less than, Greater than, Less than or equals, or Greater than or equals.
Cost	The value of the cart’s shippable items, with the same comparisons.
Quantity	The number of items quoted, with the same comparisons. With order boxing on, each packed box counts as one.
SKU	Any of the listed product SKUs (separated by commas) in the cart.

Action	Effect on matching quotes
Add / Subtract	Adds or subtracts the action value in dollars.
Fixed amount	Sets the quote to the action value.
Free shipping	Sets the quote to $0.
Disable quote	Removes the quote.

Action values are dollar amounts. A value such as 10% is read as $10.

By default a rule applies to every courier. To limit it, enter courier IDs separated by commas (for example couriers_please, allied) in the rule’s Couriers column and click the save button next to it.

How rules combine

Rules are checked from the lowest Priority number up. By default only the first matching rule is applied.

Tick Accumulate shipping rules (in the same Rules panel) to keep applying matching Postcode and SKU rules in turn. With it on, Add and Subtract stack, Fixed amount adds its value instead of replacing the price, and Free shipping and Disable quote have no effect. A matching State, Weight, Cost or Quantity rule is still applied last: no rules after it run.

Transdirect applies courier settings first, then the quote display filter, then rules.

Examples

Free shipping over $150

Trigger: Cost, Greater than, 150
Action: Free shipping
Priority: 1

Flat rate to NT postcodes

Trigger: Postcode, Range, 0800, 0899
Action: Fixed amount, 25
Priority: 2

Hide one courier for light carts

Trigger: Weight, Less than, 5
Action: Disable quote, with only that courier’s ID in the rule’s Couriers column
Priority: 3

Package-type rules

A package-type rule sets the Package type (for example Carton or Pallet) for items whose weight falls between Range from (kg) and Range to (kg), so quotes are priced with the right packaging. The weight used is the greater of the item’s actual weight and its volumetric weight. Items that match no rule keep their own package type, which is Carton unless a multi-box product sets another.
