The Managing Committee has decided that AS2 must be completely removed from the Peppol network.

AS2 was a transport protocol previously mandatory in the Peppol Network. Since February 1st, 2020 the AS4 protocol is mandatory in the Peppol Network.

As a consequence to this, all Peppol Service Providers must make sure, that the AS2 protocol is no longer used in the Peppol Network. Depending on your Peppol participation you must follow the matching objectives.

This page describes the tasks necessary to remove the AS2 transport protocol from the Peppol network.

 

Timeline:

  • This guideline takes effect immediately.

  • Peppol SPs can start immediately to remove the remainders of Peppol AS2 in their systems.

  • The complete process must be finished within the next 6 months. This means the deadline is September 6th, 2023.

 

Tasks for Peppol Capability Lookup (SMP) Providers:

  • Remove all SMP endpoints from all participants that use the transport profile busdox-transport-as2-ver1p0 (Peppol AS2 1.0) or busdox-transport-as2-ver2p0 (Peppol AS2 2.0). So only SMP endpoints using the transport profile peppol-transport-as4-v2_0 should be remaining, as this is the only supported transport profile.

  • Make sure, that in the future no SMP endpoint uses any of the AS2 transport profiles anymore.

 

Tasks for Peppol Access Point (AP) Providers:

  • Make sure to not use the AS2 protocol while using the Peppol Network

  • Make sure to stop receiving AS2 messages while using the Peppol Network

  • SMP lookups must only search for the AS4 protocol. Fallbacks to AS2 must be removed.

 

Additional information:

  • Peppol SPs don’t need to inform OpenPeppol about their progress. OpenPeppol will run respective scans automatically to see which SMP endpoints are still existing.

  • The support of AS2 will be removed from the Peppol Testbed 1.0 shortly.
