The connection is a project before it does anything.
Before the first record moves: an app registration, credentials, token refresh, and somewhere to host and monitor the code. 300 read and 300 write requests per minute per project, and 60 per minute per user per project, with 429 on excess.
Register an app, store Google Sheets credentials, refresh tokens and code around the rate limits.
Connect your Google Sheets account once. Caddi holds the connection.
The job doesn't stop at Google Sheets.
An intake, a filing or a client update also runs through email, documents and the other systems your team works in. The Google Sheets API only reaches Google Sheets.
Each extra system is another API, another set of credentials, another integration to own.
One automation runs across every tool the job touches, each through its API.
Someone has to own the code.
API versions change, fields get added and your process moves.
A developer patches and redeploys the integration each time.
The person who does the work updates it by showing or describing the change. Every automation is reviewed before it runs in production, and every run is logged.

When to build the Google Sheets integration in-house
When you have engineers and the integration is your product, or you need one narrow sync between two systems and someone to own it. When the goal is getting Google Sheets work off someone's desk, the build is the slow part, and Caddi does it for you.
What teams usually want the Google Sheets API for
Vendor Bill Creation
Caddi reads vendor payout rows and creates matching bills with the correct vendor, expense categories, and payment terms.
SOL Tracker Updates
Caddi pulls matter tracking details and updates the statute of limitations tracker sheet, reducing manual deadline data syncing for legal operations teams.
CRM ↔ Sheet sync
Caddi keeps a slice of CRM data mirrored into a Google Sheet for ops review, with changes written back to the source.
Recurring report build
Each Monday, Caddi pulls data from upstream systems, builds the weekly ops report in Sheets, and emails the link to the team.
Everything Caddi does with Google Sheets.
Google Sheets API questions
Does Google Sheets have an API?
Yes. Google Sheets has a REST API, authenticated with OAuth 2.0 (including service accounts); API key only for public data. The official documentation is at https://developers.google.com/workspace/sheets/api.
How do I get access to the Google Sheets API?
Self-serve for any developer via a Google Cloud project.
Does the Google Sheets API have rate limits?
300 read and 300 write requests per minute per project, and 60 per minute per user per project, with 429 on excess.
Can I connect Google Sheets to my other tools without writing code against its API?
Yes. With Caddi you show the Google Sheets task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across Google Sheets and the other tools the job touches. Steps that need a person's judgment are handed to Copilot or Claude, and Caddi monitors those too.
Do I need a developer to automate Google Sheets with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for Google Sheets is reviewed before it runs in production, and every run is logged.
