Integrate the OneDrive API.Caddi writes and runs the integration for you.

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. Throttling uses resource units: 1,250 to 6,250 per app per tenant per minute depending on license count, and 3,000 requests per user per 5 minutes.
Register an app, store OneDrive credentials, refresh tokens and code around the rate limits.
Connect your OneDrive account once. Caddi holds the connection.
The job doesn't stop at OneDrive.
An intake, a filing or a client update also runs through email, documents and the other systems your team works in. The OneDrive API only reaches OneDrive.
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 OneDrive 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 OneDrive work off someone's desk, the build is the slow part, and Caddi does it for you.
What teams usually want the OneDrive API for

OneDrive API questions
Does OneDrive have an API?
Yes. OneDrive has a REST API through Microsoft Graph, authenticated with OAuth 2.0 (Microsoft identity platform). The official documentation is at https://learn.microsoft.com/en-us/graph/onedrive-concept-overview.
How do I get access to the OneDrive API?
Self-serve for any developer who registers an app with the Microsoft identity platform; the app works on OneDrive personal, OneDrive for Business and SharePoint data that users or admins consent to.
Does the OneDrive API have rate limits?
Throttling uses resource units: 1,250 to 6,250 per app per tenant per minute depending on license count, and 3,000 requests per user per 5 minutes.
Can I connect OneDrive to my other tools without writing code against its API?
Yes. With Caddi you show the OneDrive task once, the way you'd train a new hire, and Caddi builds it as verified code that runs across OneDrive 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 OneDrive with Caddi?
No. There is no integration code for you to write or maintain. Every automation Caddi builds for OneDrive is reviewed before it runs in production, and every run is logged.
