Connect your Google Sheet
Do this once. After that the inventory lives in Google Sheets, so any phone or computer with this app can see the same products.
- Create a Google Sheet named Warehouse Inventory.
- Open Extensions → Apps Script.
- Delete the default code. Paste the contents of
Code.gs and save.
- Click the + next to Files → HTML → name it exactly
Index. Paste Index.html (optional — only if you want Google to host the app too).
- Deploy → New deployment → Web app. Execute as Me. Who has access: Anyone. Deploy and copy the URL.
- Paste that URL below. If you set a
TOKEN script property, enter the same PIN here.
