AS2 · EDIFACT · SFTP · REST API

B2B document exchange, without the legacy pain

Connect to any AS2 trading partner without deploying and maintaining your own AS2 server. Exchange signed and encrypted documents, receive MDNs, and integrate with your systems through SFTP or API.

If the payload is EDIFACT, AS2Expert doesn't just move it — it can validate, interpret and automate it.

Who it's for

A trading partner requires AS2. You shouldn't have to run AS2.

Primary

Companies and integrators connecting over AS2

You need to connect to a trading partner over AS2 without operating AS2 infrastructure yourself. AS2Expert gives you the endpoint, certificates, signing, encryption, MDNs and secure operation — as a service.

Also for

Teams that send or receive EDIFACT

If your documents are EDIFACT, you also need to interpret, validate and automate them — not just transport them. That is where AS2Expert goes beyond a plain AS2 gateway.

How it works

The whole path, end to end

From your partner's message to business data inside your systems — one flow.

Trading partner sends over AS2 AS2Expert endpoint signature · encryption · MDN no AS2 server on your side EDIFACT engine validate · interpret automate supported flows Your systems SFTP · REST API webhooks → ERP
For the IT team

Your partner mandates AS2. You don't need another integration server to run.

No appliance to install, no certificates to babysit on a box in a corner, no on-call for a protocol you touch twice a year. You get a working AS2 identity and the operational surface around it.

Receiving endpoint

A public AS2 URL and AS2 ID you hand to the partner.

Certificates

Generate, import, inspect and rotate without downtime.

Secure exchange

Per-partner signing and encryption over TLS.

MDNs

Synchronous or asynchronous receipts, integrity verified.

Logs & state

Per-message event history and full AS2 state.

Integration

SFTP, REST API and webhooks into your systems.

The difference

Most platforms move EDIFACT. AS2Expert understands it.

Behind every message there is a business document. AS2Expert ships a UN/EDIFACT engine built on the official UNECE directories, so a received interchange is not an opaque blob — it is a parsed, validated, readable document.

UN/EDIFACT D.93A–D.24A · 62 UNECE directories · traceable official definitions imported from pinned sources.

Parse the interchange and identify each message's type and release.
Validate structure against the official directory for that release.
Resolve segments, elements and coded values to their official meanings.
Render a human-readable representation, exportable to PDF.
Generate or assist responses where currently supported (ORDERS → ORDRSP / DESADV).
Automate supported acknowledgement flows such as CONTRL back over AS2.

End to end

Your customer sends an ORDERS message over AS2

Here is what happens — transport and document, in one place.

Where the response is currently supported, an ORDRSP or DESADV can be generated or automated. AS2Expert never promises an automation it doesn't run.

  1. AS2Expert receives the message on your endpoint.
  2. Signature and encryption are verified against the partner profile.
  3. An MDN is generated and returned, synchronously or asynchronously.
  4. The EDIFACT ORDERS is parsed and validated against its UNECE release.
  5. The business data is available through SFTP and the REST API.
  6. A response can be generated or automated where supported.
The real product

Every message shows its full technical state

AS2 message detail in the AS2Expert console: partner, station, Message-ID, and AS2 state showing encryption, signature and MDN all verified, with the full AS2 header set and an EDIFACT action.
An inbound AS2 message in the console — communication, signature, encryption and MDN state, the complete AS2 headers, and one click to the EDIFACT analysis.
Integration

Fits how your systems already work

📁

Native SFTP

Integrate without writing code. Each station is a live SFTP endpoint whose folders mirror the station.

  • Drop a file to send it, with the partner's signing/encryption policy
  • Collect received documents as files, decrypted and verified
  • Ideal for legacy systems, ERP and batch flows
⚙️

REST API & webhooks

Automate modern integrations. Everything the console does, over a token-secured JSON API, with events pushed as they happen.

  • Stations, partners, certificates, messages and sending
  • Per-partner webhooks with delivery logs
  • Scoped tokens (read / write / admin)

Use SFTP if you want simplicity. Use the API and webhooks if you want automation.
