OneDrive API: files, folders and sharing with AI agents
OneDrive is accessed by API through Microsoft Graph, which lets you list, read, upload, search and share files in OneDrive and SharePoint. Companies on Microsoft 365 use it to automate documents. Access is through an app registered in Microsoft Entra ID, with administrator consent.

What an iTeam agent does with the OneDrive API
Organizing incoming documents
The agent saves e-mail attachments in the right customer folder, with a standard name.
Search for the team
An employee asks in Teams and the agent finds the right contract or proposal.
Sharing review
The agent lists old public links and asks for approval to revoke them.
Building case files
The agent gathers the documents of a process into one folder and shares it with the auditor after approval.
From the credential to the agent at work, with approval
Register the app in Entra ID
Create the registration and grant only the file permissions needed, preferably limited to specific sites and folders.
iTeam vault
Store the secret or certificate in the vault and define, per agent, the folders and actions allowed.
Approval to share
External sharing and deletions require human approval, with an audit trail.

Questions about the OneDrive API
Is the OneDrive API free?
In general, Microsoft Graph does not charge for common file calls; storage follows your Microsoft 365 license.
Do I need to write code to use the OneDrive API with iTeam?
Not necessarily. iTeam's HTTP tool reads the API documentation and learns the endpoints, and the deployment team sets up credentials, permissions and tests with you.
Is the OneDrive API the same as Microsoft Graph?
Yes. Current API access to OneDrive and SharePoint goes through Microsoft Graph.
