Import delivery dates and times into NextEngine

This app can save the delivery date and time on orders using the attribute names and format that NextEngine reads. The app doesn't send data to NextEngine directly. NextEngine's Shopify integration reads the values from the order's Additional details.

Settings in the app

Open Integrations in the app.
Under Additional attributes, turn on Also save additional attributes.
Set the date attribute name to delivery_date and the time slot attribute name to delivery_time, and save (these names are filled in by default).

When this is on, the following two attributes are saved in addition to the usual ones. You can change the names to match your NextEngine settings.

delivery_date: the delivery date, in the form 2026/10/08 (the format can't be changed)
delivery_time: the time slot

Time slot text

NextEngine can't import time slots that contain a full-width tilde (～). The app's default time slots use the form 14時から16時, so they work as they are.

If you change a time slot to a form such as 14時～16時, set the value saved to the additional attribute (the third part after "|") to use a half-width hyphen, such as 14時-16時, under Time slot options in Integrations.

Settings in NextEngine

After you register your store in NextEngine's Shopify integration app, set up the following. Screen names are those of NextEngine's main app.

Payment and shipping methods: Under Settings > Orders > Payment and shipping conversion, map the names of your Shopify payment and shipping methods to the payment and shipping methods on NextEngine orders. Enter the names exactly.
Time slot conversion: Time slots aren't put into the order's time specification directly. They go into the remarks field first. Under Settings > Orders > Remarks conversion, choose your store, and for each time slot text, set the conversion method to convert to an item, choose the carrier's time slot as the result, and save.
Delivery date: Don't change the remarks conversion settings for the delivery date. delivery_date goes into the requested delivery date as it is.

The app's default time slots are the five below. You can copy them into the text before conversion in Remarks conversion. If you changed your time slots, use the value saved to the additional attribute (the third part after "|") under Time slot options in Integrations.

Imported orders

The delivery date and time slot are imported like this (an example with Yamato Transport time slots selected):

delivery_date: 2026/11/20 → requested delivery date 2026/11/20
delivery_time: 14時から16時 → time specification 14:00–16:00

After the conversion, a sentence such as 「配送希望時間帯は【14時から16時】です。」 stays in the remarks field. Orders with text in the remarks field are put on hold for review. To avoid this, add a remarks conversion setting that removes the sentence.

The app's other attributes (such as 配送希望日) aren't put into the remarks field.

Good to know

Attribute names must match exactly, or the values aren't imported.
When the selection type is Day of the week only, nothing is saved to the additional attributes.
