Hello,
We also received that Australia Post notification even if we didn't received any response from our previous questions about the issue that some of our customers were facing.
By checking that change log the main changes will be that :
The way you call the Service API won’t change. The same parameters of either letters or parcels will
apply, with a country code and weight to be provided. But the services codes returned will change to
match the new international services, as detailed below
And that we have to change the address where we send our Order details
our APIs are now hosted at
digitalapi.auspost.com.au/postage
We’ll decommission the old API soon.
We are currently updating and testing the Australia Post shipping plugin (v2) by using their Testing URL, so that it can be available before the 31 may 2016.
Thank you for your feedback.
