Getting Started

About the API

The Publishing Direct system allows Market Participants to access data, subscriptions, message delivery logs and calendars to the EMMS Wholesale Market System. AEMO uses three instances of the Publishing Direct system based on the publishing Business ID. You can access these systems using the AEMO Markets Portal.

The APIs listed in this chapter allow you to access specific details from the Publishing Direct system depending on the request parameters. Settlements Direct is an instance of the Publishing Direct system.

To access the Publishing Direct systems on the Markets Portal, navigate as follows:

  • For Settlements Direct: Settlements Direct, MMS Markets Portal > MMS > Settlements > Settlements Direct.

  • Publishing Direct for GSH – To access Publishing Direct, MMS Markets Portal > Gas Supply Hub > Publishing Direct.

  • Market Direct for Market Info – To access Market Direct, MMS Markets Portal > Market Info > Market Direct.

Getting Access

To access Settlements Direct, Participant Users must have the appropriate user rights access. The access right determines the functionalities and transactions you can use to access the web portal, batch interfaces, FTP, and API services.

Participant Administrators (PAs) authorise Participant User access in MSATS. The initial PA is set up by the AEMO system administrator as part of the registration process.

Your company's participant administrator (PA) grants you permission to use NEM Credit Support.

The MSATS entity required for Settlements Direct access is:

  • MMS_SETTLEMENTS_DIRECT

  • MMS_SETTLEMENTS_DIRECT_PUBLISH

  • MMS_SETTLEMENTS_DIRECT_ SUBSCRIBE

During formal onboarding, you will first be given access to Pre-Production and must complete your development/testing there prior to getting access to Production.
