- ~45 minon average to build your first agent
- 1M+back-office tasks completed
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. 10,000 requests/minute per project and 600 requests/minute per user per project, with a 1,000,000 requests/day per-project billing threshold.
Register an app, store Google Calendar credentials, refresh tokens and code around the rate limits.
Connect your Google Calendar account once. Caddi holds the connection.
The job doesn't stop at Google Calendar.
An intake, a filing or a client update also runs through email, documents and the other systems your team works in. The Google Calendar API only reaches Google Calendar.
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 Calendar 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 Calendar work off someone's desk, the build is the slow part, and Caddi does it for you.
What teams usually want the Google Calendar API for
Pre-meeting prep packet
Caddi reads the day's calendar, matches each meeting to a CRM record, and emails the host a prep packet with key context.
Time-entry drafts
Caddi turns yesterday's calendar into a draft set of billable time entries against the right matters, queued for review.
Follow-up tasks from events
Once a meeting ends, Caddi opens the right follow-up tasks in your project or matter system and notifies the attendee.
Everything Caddi does with Google Calendar.
Google Calendar API questions

Does the Google Calendar API have rate limits?
10,000 requests/minute per project and 600 requests/minute per user per project, with a 1,000,000 requests/day per-project billing threshold.
Can I connect Google Calendar to my other tools without writing code against its API?
Yes. With Caddi you show the Google Calendar task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across Google Calendar 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 Calendar with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for Google Calendar is reviewed before it runs in production, and every run is logged.
