Google Sheets APIConnect Google Sheets without building on its API
Google Sheets has a REST API. Self-serve for any developer via a Google Cloud project. If you're reading the docs because you need Google Sheets to talk to the rest of your stack, Caddi does that without you writing or maintaining integration code: you show it the job once, and it runs it across Google Sheets and your other tools.

Building on the Google Sheets API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get Google Sheets credentials, and manage tokens and refreshes. | Connect your Google Sheets account once. Caddi holds the connection. |
| Writing the integration | A developer maps fields, handles pagination, retries and rate limits, and writes the sync. | You show Caddi the Google Sheets task the way you'd train a new hire. It writes verified code for it. |
| Steps the API doesn't cover | Screens with no endpoint stay manual, or need a separate RPA tool. | Caddi uses a secure, audited browser session where there's no API, in the same automation. |
| The other systems in the loop | Each extra tool is another API, another set of credentials, another integration to own. | One automation runs across all the tools the job touches. |
| Keeping it running | Someone owns the code when the API version, fields or your process change. | Every automation is reviewed before it runs in production, and every run is logged. |
Building on the API is the right call when you have engineers and the integration is your product. When the goal is getting Google Sheets work off someone's desk, the build is the slow part.
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.
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. Where a step has no API, Caddi uses a secure, audited browser session in the same automation.
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.
