Specifying transit durations for zones

You can specify the transit duration for zones such that all the origin and destination pairs within each zone inherit the same transit duration. You can also specify transit delays for the zones to enhance accuracy of transit duration calculations.

Note: Specifying transit delay for the transit duration calculations is an optional action. You can specify it only when you need to introduce ad hoc delays for carrier transit durations.

An individual origin-and-destination postal code combination within a zone is called zone component or zone route.

First, identify all zone components within a shipping zone. For example, the ROMSTANDARD_EFC_GB_LT2 shipping zone contains the following two zone components.
zone destination_country origin_country destination_postal_code_begin destination_postal_code_end origin_postal_code_begin origin_postal_code_end
ROMSTANDARD_EFC_GB_LT2 GB DE AB1 AB6 495 495
ROMSTANDARD_EFC_GB_LT2 GB DE AB9 AB9 495 495
Then, define the transit duration for the shipping zone. Optionally, specify transit delay for the zone.
zone transit_duration transit_delay
ROMSTANDARD_EFC_GB_LT2 PT72H PT24H

To remove the previously configured transit delay, leave the transit_delay value blank.
