Hello,
After several tests we reproduced it with the same result even if a request for the "FIRSTCLASSINT" was made, here are the information sent to the USPS platform without the "First class international" service returned (Without the Robotech Macross VF-1S Full Armoured Version product in the cart) :
<?xml version="1.0"?><IntlRateV2Request USERID="XXXXXXX"><Revision>2</Revision><Package ID="1"><Pounds>0</Pounds><Ounces>1</Ounces><Machinable>false</Machinable><MailType>Package</MailType><ValueOfContents>100</ValueOfContents><Country>Canada</Country><Container>VARIABLE</Container><Size>Regular</Size><Width>3</Width><Length>6</Length><Height>0.45</Height><Girth>12.9</Girth><OriginZip>53142</OriginZip></Package></IntlRateV2Request>
And here is what is sent when the First class international service is returned (With the Robotech Macross VF-1S Full Armoured Version product in the cart) :
<?xml version="1.0"?><IntlRateV2Request USERID="XXXXXXX"><Revision>2</Revision><Package ID="1"><Pounds>0</Pounds><Ounces>3.9</Ounces><Machinable>false</Machinable><MailType>Package</MailType><ValueOfContents>100</ValueOfContents><Country>Canada</Country><Container>VARIABLE</Container><Size>Regular</Size><Width>4</Width><Length>7</Length><Height>2.95</Height><Girth>20.9</Girth><OriginZip>53142</OriginZip></Package></IntlRateV2Request>
The best would be to directly ask them why no rates were returned for the first class international service with these datas as we couldn't find any issue with the way these information were sent.
Kind regards,
Mohamed.
