OSO Stamps.com Tracking Sync

Internal tool for Sensible Edibles bakery. Auto-syncs UPS tracking numbers from print.stamps.com shipped rows to our OSO (Order Status Operations) system so customers automatically receive shipping notifications. After you print labels on stamps.com, the extension scrapes each shipped row's Order ID and Tracking number, then POSTs them to our private Google Apps Script endpoint. Matching is done by Shopify Order ID, so trackings flow into the correct customer record. Already-synced trackings are cached locally to prevent duplicates. Not intended for use outside our organization.
