Add landed costs (duties and import fees) to this method's price, overriding the experience-level setting. [ShippingMethodCarrierServiceInput!]}> Dynamic methods only. The carrier services to quote live rates from. Required unless `serviceLevel` is set. ShippingCarrier!} required> Carrier to quote live rates from. Values are display-cased, e.g. 'FedEx', 'UPS', 'USPS'. Whether this carrier service is quoted. Defaults to true. ShippingMethodCarrierServiceMarkupInput}> Markup applied to this carrier service specifically. Decimal}> Flat markup for this service, as a decimal string. Decimal}> Percentage markup for this service, as a decimal string. Carrier-specific service code, e.g. 'FEDEX\_GROUND' for FedEx or 'Ground' for UPS. The valid set differs per carrier; read an existing dynamic method with checkoutExperience(id:) to see the codes this store already uses. ShippingMethodCoverageTypesInput}> Redo coverage bundled into this shipping method. Include package protection with this method. Include return coverage with this method. Shopper-facing description shown next to the method at checkout. Like `name`, it may contain customer-name template variables. [ShippingCarrier!]}> Dynamic methods only. Carriers excluded from this method's candidate set. Shopper-facing description used in place of `description` under the same condition as `fallbackName`. Shopper-facing name used in place of `name` when `name` contains customer-name template variables and the shopper's name is not available at quote time. Ignored when `name` has no variables. Dynamic methods only. Days Redo assumes an order takes to ship when it estimates delivery dates for this method, overriding the experience's `fulfillmentDelayDaysOverride`. Omit it to use the experience's value. A whole number of days, zero or more. ShippingMethodMarkupInput}> Dynamic methods only. Markup applied to every live carrier rate on this method. Decimal}> Flat markup as a decimal string. Currency of the flat markup. Required when `amount` is set. Decimal}> Percentage markup as a decimal string, e.g. '10' for +10%. Shopper-facing name of the shipping method as it appears at checkout, e.g. 'Standard'. May contain customer-name template variables — '\{customer\_name}', '\{customer\_name:first}', '\{customer\_name:last}' — which are substituted per shopper. Send them back verbatim when you are not deliberately changing them, or you will silently strip the merchant's personalization. Tags applied to the order when this method is bought. ShippingMethodPriceBoundsInput}> Dynamic methods only. Hard clamp applied after markup and rounding. Currency of the bounds. Decimal}> Highest price ever shown, as a decimal string. Decimal}> Lowest price ever shown, as a decimal string. ShippingMethodPriceConstraintsInput}> Bounds the final price this method may be sold at, after every other pricing rule has run. Omit to leave the method's existing constraint untouched; send one to replace it outright. There is no way to clear a constraint through this API. Floor applied after the relative bound: the effective minimum is the greater of this and the referenced price plus `byAtLeast`. 'RELATIVE\_TO\_OTHER\_RATE\_TABLE' constraints only. ShippingMethodPriceInequalityInput}> How far above the referenced method's price this method must sit. 'RELATIVE\_TO\_OTHER\_RATE\_TABLE' constraints only. Absolute amount of the bound. Omit when unset. Percentage form of the bound. Omit when unset. ShippingMethodPriceInequalityInput}> How far above the referenced method's price this method may sit. 'RELATIVE\_TO\_OTHER\_RATE\_TABLE' constraints only. Absolute amount of the bound. Omit when unset. Percentage form of the bound. Omit when unset. Currency all bounds are expressed in. ShippingMethodPriceConstraintKind!} required> How the bounds are expressed: 'DEFAULT' bounds the price absolutely, 'RELATIVE\_TO\_OTHER\_RATE\_TABLE' bounds it against another shipping method's price. ShippingMethodPriceInequalityInput}> Suggested lower margin bound. Omit when there is none. Absolute amount of the bound. Omit when unset. Percentage form of the bound. Omit when unset. ShippingMethodPriceInequalityInput}> Suggested upper margin bound. Omit when there is none. Absolute amount of the bound. Omit when unset. Percentage form of the bound. Omit when unset. Highest price this method may be sold at. 'DEFAULT' constraints only. Lowest price this method may be sold at. 'DEFAULT' constraints only. ID of the shipping method this method's price is bounded against, from the same checkout experience. Required for, and only valid on, 'RELATIVE\_TO\_OTHER\_RATE\_TABLE' constraints. ShippingMethodRateSelection}> Dynamic methods only. Which of the eligible live rates to show the shopper. Values are CHEAPEST, FASTEST, and CUSTOM. [ShippingMethodRateInput!]}> Fixed methods only, and required for them. One entry per price. A single entry with no `conditions` is a flat price; multiple entries express weight or cart-value ranges and free-shipping thresholds. [ShippingMethodConditionInput!]}> Cart weight or cart value ranges this rate applies to. Omit or pass an empty array for a flat price that applies to every cart. Currency of the cart value bounds. Price conditions only. Inclusive upper bound of cart weight. Weight conditions only. Inclusive upper bound of cart value. Price conditions only. Inclusive lower bound of cart weight. Weight conditions only. Inclusive lower bound of cart value. Price conditions only. ShippingMethodConditionType!} required> What this condition is measured against: WEIGHT for cart weight, PRICE for cart value. ISO currency code for `price`, e.g. 'USD'. Whether this rate is active. Defaults to true. Decimal!} required> Price for this rate as a decimal string, e.g. '5.99'. Use '0' for free shipping. ShippingMethodRounding}> Dynamic methods only. How to round the marked-up price before showing it. Identifier the storefront platform uses for this shipping option at checkout. ShippingMethodServiceLevel}> Dynamic methods only. Quote the cheapest carrier service delivering within this service level's window instead of pinning carrier services. WritableShippingMethodType!} required> How the price is produced. FIXED is a merchant-set price served by Redo with no carrier involved and requires `rates`. DYNAMIC quotes live carrier rates through Redo and requires either `carrierServices` or `serviceLevel`. Custom (script-priced) methods cannot be created or edited here. This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
