WEM API Access

All externally accessible APIs provided by AEMO in the Wholesale Electricity Market (WEM) are documented on our Developer Portal.

AEMO is progressively transitioning our APIs to an API Management (APIM) platform, which intermediates access to AEMO’s external APIs. To date, all WEM APIs, except for the Prudential and Settlement Service (PaSS) APIs, have transitioned to the APIM platform.

Users require different certificates to access APIs, depending on whether the API in question is hosted in the APIM or not:

• Accessing APIs on our APIM platform (i.e. most of them) requires a DigiCert Certificate.
• Accessing our Prudential and Settlement Service (PaSS) APIs requires a Local Certificate.
