USPS wants XML eCart generates PHP...

I originally set up to get shipping cost estimate from UPS; this worked fine. My client decided to change to US Postal Service shipping. eCart generated the code for this, but USPS rejects the request.

eCart generated this code:
$Shipping_Parameters["UserID"] = "1234567";
$Shipping_Parameters["Password"] = "89101112";
$Shipping_Parameters["USPSServer"] = "http://production.shippingapis.com/shippingapi.dll";
$Shipping_Parameters["CarrierCode"] = "PRIORITY";
$Shipping_Parameters["DefaultIntl"] = "First-Class Mail International Package";
$Shipping_Parameters["ShipperZip"] = "48915";

But it says "production.shippingapis" and I know they have to approve you for "production" so I changed that line to what USPS sent, which was:
$Shipping_Parameters["USPSServer"] = "http://testing.shippingapis.com/ShippingAPITest.dll";

This was also rejected.

Perhaps because the email from USPS says the code to send them should look like this (for the testing server):

" A sample test request would look like: "http://testing.shippingapis.com/ShippingAPITest.dll?API=[API_Name]&XML=[XML_String_containing_User_ID]" "

What should I do here? I'm getting to understand PHP, but mixing it with XML is new to me...

the php code of eCart generates an xml request that is sent to USPS.

eCart uses the V3 rate request API which is not supported on the testing server, you will need to use the production server address, and contact USPS to have you account updated to use the production server.


if it is still failing, open the shipping failure page, and go to the bindings panel, there will be a USPS Binding group, expand that and add the Full Request and Full Response bindings to the page, this will help us debug the cause by showing the response coming back from USPS.

I just noticed there is a "eCart 5: Support Fix - Updated USPS Shipping Rate Lookup API" which gives me a new WA_eCart_USPS_PHP.php file. Maybe this will resolve my problem, however when I try using it the cart doesn't go thru to shipping_failure.php, but instead stalls while still in confirm.php with the error message:

Notice: Undefined variable: USPS_PkCount in /Applications/MAMP/htdocs/ProRes_Shipping/WA_eCart/WA_eCart_USPS_PHP.php on line 129 (it repeats this error for lines 134 & 170)

If you can help me resolve this error, then maybe I can get to the point of connecting to the Postal Service...

you started another thread for this issue, where i opened a support ticket so we can investigate the issue with your over the phone.
