Getting Started

About the API

The meter exemption APIs allow Registered Metering Co-Ordinator's (MCs) to create and manage metering exemptions within MSATS.

Before you can use the Meter Exemptions API you must:

  • Have a Participant ID with an effective date of registration. If your company is a Registered Participant, it is set up during the registration process.

  • Have a user ID and password with access rights provided by your company's participant administrator. For details, see user rights access below.

  • Understand the procedures governing the operation of the market relating to
    wholesale trading of electricity and the provision of ancillary services. For
    details, see the NER Chapter 3, Introduction to Market Rules.

  • Have an API gateway and a TLS certificate.

  • Test your submission in the pre-production environment before submitting to production. AEMO encourages participants to use the pre-production environment to test procedures and train staff.

  • Participant Users require access rights to create or view API or web meter exemptions
