Collect files from any S3-compatible bucket into SharePoint

DocEvent polls your S3 or S3-compatible bucket on a schedule — Cloudflare R2, MinIO, Backblaze B2, Wasabi or Amazon S3 — and delivers each collected file into a Microsoft 365 SharePoint document library. No bucket notifications or event plumbing needed.

How S3 Compatible (pull) to SharePoint routing works

Source

S3 Compatible

DocEvent checks your S3 or S3-compatible bucket on a schedule and collects new files — Cloudflare R2, MinIO, Backblaze B2, Wasabi and more.
DocEvent Channel
routes · retries · logs
Destination

SharePoint

Files are delivered into a SharePoint document library.
1

File arrives via S3 Compatible (pull)

Scheduled polling of any bucket that speaks the S3 API — Amazon S3, Cloudflare R2, MinIO, Backblaze B2, Wasabi, Supabase Storage and friends (custom endpoint URL and path-style addressing supported). Collects from a prefix with filename pattern filtering, then each collected file is deleted or moved to an archive prefix. No bucket notifications or event plumbing needed.
2

Channel routes it

DocEvent's channel server matches the incoming file to your configured route, queues it for delivery, and ensures no file is ever lost — even during downstream outages.
3

Delivered to SharePoint

Delivery into a Microsoft 365 SharePoint document library through the Microsoft Graph API, using a reusable Microsoft connection rather than a secret pasted onto the endpoint. Pick the site, library and destination folder, and decide what happens when the name already exists — keep both, replace it (SharePoint keeps the version history), or fail the delivery. Large files are uploaded in chunks.

Common use cases

Real workflows that teams automate with a S3 Compatible (pull) → SharePoint channel.
  • Publish objects from Cloudflare R2, MinIO, B2 or Wasabi into Microsoft 365
  • Give staff SharePoint access to a self-hosted object store
  • Move files from a bucket that has no event notifications set up
  • Archive bucket output where business users can find it
The two ends don't have to be the same company — invite a customer or trading partner into the channel and they run the S3 Compatible (pull) or SharePoint side under their own account, with their own credentials. Learn how shared channels work.
