Google Docs APIConnect Google Docs without building on its API
Google Docs has a REST API. Self-serve for any developer through a Google Cloud project. If you're reading the docs because you need Google Docs 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 Docs and your other tools.

Building on the Google Docs API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get Google Docs credentials, and manage tokens and refreshes. | Connect your Google Docs 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 Docs 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 Docs work off someone's desk, the build is the slow part.
What teams usually want the Google Docs API for
Doc generation from CRM
Caddi populates a Google Docs template with current CRM data and routes the draft to the right reviewer.
Approved-draft to signature
Once a Google Doc is approved, Caddi exports it as a PDF and kicks off the signature workflow.
Archive + record update
When a Google Doc is finalized, Caddi files it in your DMS with the right metadata and updates the matching CRM record.
Google Docs API questions
Does Google Docs have an API?
Yes. Google Docs has a REST API, authenticated with OAuth 2.0 (user consent or service account). The official documentation is at https://developers.google.com/workspace/docs/api/how-tos/overview.
How do I get access to the Google Docs API?
Self-serve for any developer through a Google Cloud project.
Does the Google Docs API have rate limits?
Reads are capped at 3,000/min per project and 300/min per user, and writes at 600/min per project and 60/min per user.
Can I connect Google Docs to my other tools without writing code against its API?
Yes. With Caddi you show the Google Docs task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across Google Docs 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 Docs with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for Google Docs is reviewed before it runs in production, and every run is logged.
