Update 3/25/2021 the issue with the integration was fixed so this script is no longer required.

SquarespaceShipstationFixer

Shipstation's Squarespace integration doesn't import orders that are missing postal codes. This Google Apps Script resends those orders with a 00000 postal code.

To use:

1. Copy the .gs files into an AppsScript project.
2. In the runForFirstRun function, replace "YOUR_KEYS" with your keys for Shipstation and Squarespace. For Squarespace, use read-only Orders API permissions when creating the key.
3. In the debugger, run the runForFirstRun function.
4. Set up a time-based trigger for the script that calls the mainWrapper function.
