I received an email from Australia Post which read:
"Important API Update
Dear API Developer Community,
As part of an update to our infrastructure, we will replace the current SSL Certificate on 10 February 2019 at 13:00 AEDT.
Who will it impact?
Anyone using our Shipping & Tracking, Postage Assessment Calculator, Delivery Choice and all other APIs via auspost.com.au, digitalapi.auspost.com.au or api.auspost.com.au, and has previously manually imported our SSL Certificate into a trusted certificate store.
What should I do?
Consult your developer or plugin provider to see if your application or website is affected. If needed, download and import the new certificate into your trust store."
It also included a download link for crt files. I was wondering if this updated is required for the Australia Post module to work, if it would have any effect on it at all or if it would continue to work?
