Collect files from your SFTP server and send them as AS2
DocEvent polls your SFTP server over SSH on a schedule, collects each new file, then signs, encrypts and delivers it to your trading partner over AS2, tracking the MDN receipt. Host-key verification on the pull, certificates and protocol handled on the AS2 side.

How SFTP Pull to AS2 routing works
Source
SFTP Pull
DocEvent connects to your SFTP server on a schedule and collects new files.
DocEvent Channel
routes · retries · logs
Destination
AS2
Files are delivered to an AS2 trading partner — signed, encrypted, and tracked until the MDN receipt comes back.
1
File arrives via SFTP Pull
Scheduled outbound polling of any SFTP server over SSH — nothing to install on it. Host-key verification, filename pattern filtering, completed-file detection, then each collected file is deleted or moved to a processed folder.
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 SFTP Pull → AS2 channel.
- Transmit EDI that an internal system writes to an SFTP outbox
- Front an SFTP-based process with a compliant AS2 channel
- Give a partner AS2 while your systems keep using SSH internally
- Schedule AS2 transmissions off an existing SFTP directory
The two ends don't have to be the same company — invite a customer or trading partner into the channel and they run the SFTP Pull or AS2 side under their own account, with their own credentials. Learn how shared channels work.
