LS-ATO Specifications

The smallest, fastest and most feature-rich ebMS3/AS4 client for the ATO’s SBR system.

Overview

LS-ATO is a small, fast, secure and standards-compliant ebMS3/AS4 client custom-built for the ATO.

Though the ATO’s SBR system is complex, LS-ATO hides this complexity behind a simple command line interface, which makes it easy to integrate with business applications.

LS-ATO supports the full range of SBR requirements including:

All ATO services (e.g. IITR, FBT, AS, CUREL, STP, TFND, TPAR, SMAT2, STIC)
All ATO actions (e.g. submit, validate, list, search)
All ATO extensions (e.g. roles, delegations, legacy modes)
All message types (synchronous, batch, bulk, batch-of-bulk, collect)
Strong security (e.g. SAML, signing, authorisations, MyGovID M2M keystore)
Custom ATO formats (e.g. payloads, responses, errors)
ATO customisations (e.g. ATO endpoints and routes, polling, compression, extensions).

Architecture

LS-ATO is a simple, all-inclusive, tiny (4 MB) executable.

Applications - interface to LS-ATO using a simple command line interface.
Messaging - is made simple by hiding all the details (AS4, SAML tokens, M2M keystore).
Operations - is easy with just a few files to manage (configuration file, log file, result files).
