Connect Google Workspace to Hypamoon
Yes, with one catch. Google Workspace 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.
OpenThe check
Three questions about the API of Google Workspace, answered from its own docs.
- Public API docs
- Yes. Gmail, Calendar and Drive each have their own public API docs. Read the docs
- A key you create yourself
- Yes. Create an OAuth client or a service account in your own Google Cloud project. Sensitive and restricted scopes need Google's app verification before outside users can use the app. developers.google.com
- Versions or a changelog
- Yes. Versioned APIs (Gmail v1, Calendar v3, Drive v3) with release notes. developers.google.com
- How it signs in
- OAuth 2.0 with a client you create in your own Google Cloud project. Workspace admins can instead use a service account with domain-wide delegation, which a Super Admin authorizes in the Admin console.
- Webhooks
- Yes. It can tell your app when something changes. developers.google.com
- Hosting
- Cloud
What you can build
Search mail and calendar events, look up files in Drive, and draft emails or add calendar events from your chat.
Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work
Good to know
- Google Workspace 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 Workspace takes more work: ask your chat to check this first.
- Gmail scopes that read mail are restricted: an app used outside your own organization needs Google's verification and, if it stores mail data on servers, a security assessment. Gmail push uses Pub/Sub and Calendar push channels expire, so both need renewing.

Google Workspace is a name of its owner, used here only to describe the software. This page is not an official integration and Hypamoon has no partnership with Google Workspace. Found something that changed? Tell us at support.
Tool not listed? Ask the chat to check its API.
The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
Fill in the name of your software. Checking needs no connection to Hypamoon.
