How GCS Blob Pull to SFTP routing works
Source
Google Cloud Storage
DocEvent checks your Google Cloud Storage bucket on a schedule and collects new blobs — no Pub/Sub or notifications needed.

Files are pushed securely to an SFTP server over SSH.
1
File arrives via GCS Blob Pull
Scheduled polling of a Google Cloud Storage bucket using a service-account key. Collects blobs from a prefix with filename pattern filtering, then each collected file is deleted or moved to an archive prefix. No Pub/Sub, no bucket notifications, no event plumbing.
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 SFTP
SSH key or password authentication. Standard port 22. Configurable remote path.
Common use cases
Real workflows that teams automate with a GCS Blob Pull → SFTP channel.
- Deliver GCS files to banks or insurers that only accept SFTP
- Automate regulated submissions straight from a GCS bucket
- Bridge Google Cloud pipelines to partners on SFTP infrastructure
- Replace scripted gsutil downloads and manual SFTP uploads
The two ends don't have to be the same company — invite a customer or trading partner into the channel and they run the GCS Blob Pull or SFTP side under their own account, with their own credentials. Learn how shared channels work.
