USPS International Shipping

Using the standard wizard settings gives the following code block

$Shipping_Parameters["USPSServer"] = "http://Production.ShippingAPIs.com/ShippingAPI.dll";
  $Shipping_Parameters["CarrierCode"] = "PRIORITY";
  $Shipping_Parameters["DefaultIntl"] = "Airmail Parcel Post";
  $Shipping_Parameters["ShipperZip"] = "10701";
  $Shipping_Parameters["ShiptoZip"] = "".((isset($_POST["shipping_postcode"]))?$_POST["shipping_postcode"]:"")  ."";
  $Shipping_Parameters["ShiptoCountry"] = "".((isset($_POST["shipping_country"]))?$_POST["shipping_country"]:"")  ."";

but when testing with my own address shipping fails and returns the following

DomesticRatesV3;RateEngineV3.ProcessRequest - Please enter a valid ZIP Code for the recipient.
-2147219497
0
API=RateV3&XML=PRIORITY10701CV47 9QP50REGULAR
-2147219497DomesticRatesV3;RateEngineV3.ProcessRequestPlease enter a valid ZIP Code for the recipient. 1000440

What am I missing to get USPS to work with international addresses ?

Domestic US addresses seem to work just fine.

The error is saying the Ship To Zip value is not valid.

When you get the error, what is the value of the $_POST["shipping_postcode"]?

<input type="hidden" name="shipping_postcode" id="shipping_postcode" value="CV47 9QP" />

This field contains the post value.

Is this hidden form element code on the confirm page?

Usually with shipping rate lookup, it is triggered when the checkout page posts to the confirm page, then again when the confirm page posts to itself.

Are you getting the failure when the checkout page posts to the confirm page? What is the value of the shipping_postcode form element on the checkout page?

Hi Jason,

Yes the checkout posts to the confirm page and then it fails, the code in the USPS code block is like so:

$Shipping_Parameters["ShiptoZip"] = "".((isset($_POST["shipping_postcode"]))?$_POST["shipping_postcode"]:"")  ."";

and this is the same value as the hidden form field I posted earlier i.e. "CV47 9QP"

What about the $_POST["shipping_country"]? For USPS Rate look up to use the international API, the $_POST["shipping_country"] cannot be set to US.

I just tested a rate lookup where I hardcoded the value for ship to country and ship to zip:

$Shipping_Parameters["ShiptoZip"] = "CV47 9QP";

$Shipping_Parameters["ShiptoCountry"] = "UK";

and got a successful shipping rate back.

Jason,

thanks I am getting closer now the error message being returned is

-2147218046IntlPostage;clsIntlPostage.GetCountryInfo;clsIntlPostage.CalcAllPostage;IntlRate.ProcessRequestInvalid Country Name1000440

these are the post values

shipping_postcode	CV47 9QP
shipping_country	UK

Having done a little more research interestingly a ShiptoCountry value of United Kingdom (Great Britain) returns a shipping value

But I cannot get a ShiptoCountry value of UK to return a value

try GB instead of UK for the ship to country.

yep that returns a result as well
