What you need to get started:

Before getting started with Australia Post eParcel you will need a few things. 

  • Australia Post eParcel Account Number
  • Australia Post API Key & Australia Post API Secret
    If you are missing any of these credentials, generate an API key and Secret through the eParcel developers center.

How to set up Australia Post eParcel:

1. Enter your API details in Starshipit

  1. Go to Settings > Couriers > Add New Courier > Australia Post.
  2. Tick Enable Australia Post.
  3. Enter your Account Number, Authorisation Key, and Password (API Secret).
  4. Click on Look-up to get your MLID.
  5. For the current increment, this will only need to be changed if you have used this Australia Post account on another platform or integration. If you have, we recommend increasing the base number by 1 million. This value should not exceed 7 digits.
