Australia Post real time rates for letter doesn't return rate

The real time rate works ok for packages but not for letters.

It appears to be because dimensions are sent for letters, this conflicts with the api specification (linked). I have reviewed logic of app/Tygh/Shippings/Services/Aup.php and this sends dimension for both letters and packages
packages = required
letters = invalid

to replicate

  • set up a real time postage method to a package type.
  • set product box dimensions to minimum e.g. 1 x 1 x 1
  • test works ok, live package in store works ok,
  • switch real time postage method to a letter type
  • test works ok but live product will not.

Test requests sent to Australia Post from the storefront and from the admin panel (when using “test”) use the same data structure, so there should be no difference. Please check that all other settings are correct.

I don’t believe the test structure sends dimensions, which is why I think the live provides an error, whatever the reason it doesn’t work when letters are selected but does work when package selects. The item being tested from storefront (as opposed to test calculation within admin panel) weight is set too 0.05 and length of 1x1x1

You can check the last HTTP/HTTPS requests at the Administration > Logs page of your admin panel. It will contain both the parameters that were sent in the request and its response.

Please check them and let me know the results.

Ta. Both the admin panel test and cart request seem to include dimensions. It seems the bug is that the weight is being sent as 250kg for the letter but .250kg for the package … that said it works ok for the admin panel test. Saids that service code is wrong, but it is the same service code for the admin panel test!!! Maybe it is that the cart test adds a decimal point and the admin panel test doesn’t.

I place my bid that it is caused by the fact that delivery is requested from the place ‘A’ back to the place ‘A’ again.

‘from_postcode’ => ‘5114’, ‘to_postcode’ => ‘5114’

Weight is specified in grams, so you don’t need to be afraid of large numbers :smiley:

Same result with different postcode
