Send files from Google Cloud Storage to an AS2 partner
DocEvent polls your Google Cloud Storage bucket on a schedule with a service-account key and transmits each collected blob to your trading partner over AS2 — signed, encrypted and MDN-tracked. No Pub/Sub plumbing and no AS2 software.

How GCS Blob Pull to AS2 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.
DocEvent Channel

Destination
AS2
Files are delivered to an AS2 trading partner — signed, encrypted, and tracked until the MDN receipt comes back.
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 AS2
Outbound AS2 (RFC 4130) delivery to your partner's AS2 URL. Messages are signed (SHA-256, SHA-384 or SHA-512) and encrypted (AES-256, AES-192, AES-128 or 3DES for legacy partners) using the partner's certificate, and can be compressed. Ask for a synchronous MDN, an asynchronous MDN, or none at all — signed receipts are verified and recorded, and a message whose receipt never arrives is parked for reprocessing instead of being quietly lost. Re-sends carry the same Message-ID, so a partner's duplicate detection suppresses them.
Common use cases
Real workflows that teams automate with a GCS Blob Pull → AS2 channel.
- Transmit EDI produced by a pipeline that writes to GCS
- Give a Google Cloud workload AS2 connectivity with no AS2 library
- Send partner documents from a GCS bucket on a schedule
- Bridge BigQuery or Dataflow output to a trading partner over AS2
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 AS2 side under their own account, with their own credentials. Learn how shared channels work.
