Connect Google Sheets to Hypamoon

Yes, with one catch. Google Sheets has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today.

Open

The check

Three questions about the API of Google Sheets, answered from its own docs.

Public API docs
Yes. Read the docs
A key you create yourself
Yes. Create an OAuth client or a service account yourself in your own Google Cloud project; for Workspace, a Super Admin can grant domain-wide delegation. developers.google.com
Versions or a changelog
Yes. Versioned REST API, v4. developers.google.com
How it signs in
OAuth 2.0 with a client from your own Google Cloud project, or a service account with domain-wide delegation in a Workspace domain.
Webhooks
Not confirmed.
Hosting
Cloud

Your own app on top of your Google Sheets, with sign-in and a real form.

  • Spreadsheets, tabs and cell ranges, straight from Google Sheets.
  • AI that checks new rows, fills in what is missing and flags what looks wrong.
  • Screens for your team and customers, and an email when a row changes.

Ask your chat

Answers straight from your Google Sheets data, in Claude or another chat with the full Hypamoon connection.

  • What was the total of the orders tab last month?
  • Which rows in the planning sheet have no owner yet?

On a schedule

Google Sheets has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next.

  1. Every 15 minutes

    New rows in the intake tab since the last check.

    AI decides

    AI reads each row and fills in the category and the owner.

    Then

    The missing cells are filled in the sheet.

    AI proposes, you approve

A screen for your team or customers

An app on your own address, with sign-in, on top of the same Google Sheets data.

  • For your team

    A simple form and overview for the team, while the data stays in your sheet.

Google Sheets stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Google Sheets waits for your approval, one call at a time. How adapters work

Good to know

  • Google Sheets signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Google Sheets takes more work: ask your chat to check this first.
  • Part of Google Workspace, which has its own entry; this entry is for people looking for this app on its own. A service account can be given access by sharing the sheet with its address.
