OneDrive APIConnect OneDrive without building on its API
OneDrive has a REST API through Microsoft Graph. 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. If you're reading the docs because you need OneDrive 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 OneDrive and your other tools.

Building on the OneDrive API vs. having Caddi run it
| The job | Build it on the API | With Caddi |
|---|---|---|
| Getting access | Register an app, get OneDrive credentials, and manage tokens and refreshes. | Connect your OneDrive 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 OneDrive 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 OneDrive work off someone's desk, the build is the slow part.
What teams usually want the OneDrive API for
New Hire Tracker Cleanup
Caddi manages new hire onboarding follow-ups in an Excel tracker by categorizing employees, updating tracking fields, and removing duplicate entries.
Excel Transaction Sync
Caddi transfers new deal transaction data between Excel worksheets by creating a row for each transaction and mapping source values into the destination sheet.
Onboarding Tracker Cleanup
Caddi manages onboarding follow-ups from an onboarding report by classifying employees, updating tracker fields, and removing duplicate entries.
Financial Report Archiving
Caddi generates client financial report PDFs and archives them with the correct template and metadata, reducing manual report handling for financial planning teams.
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. Where a step has no API, Caddi uses a secure, audited browser session in the same automation.
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.
