*MUST* follow the instructions in this email to obtain access to the production

rate quote server. THIS USERTAG WILL NOT WORK WITH USPS's TEST SERVER.

=head1 PARAMETERS

=head2 Base Parameters (always required):

=over 4

=item service

The USPS service you wish to get a rate quote for. Services currently supported:

EXPRESS

FIRST CLASS

PRIORITY

PARCEL

BPM

LIBRARY

MEDIA

GLOBAL EXPRESS MAIL (EMS)

GLOBAL PRIORITY MAIL - FLAT-RATE ENVELOPE (LARGE)

GLOBAL PRIORITY MAIL - FLAT-RATE ENVELOPE (SMALL)

GLOBAL PRIORITY MAIL - VARIABLE WEIGHT (SINGLE)

AIRMAIL LETTER-POST

AIRMAIL PARCEL POST

ECONOMY (SURFACE) LETTER-POST

ECONOMY (SURFACE) PARCEL POST

MATTER FOR THE BLIND - ECONOMY MAIL

=item weight

The total weight of the items to be mailed/shipped.

=item userid

Your USPS webtools userid, which was obtained by registering.

This will default to $Variable->{USPS_ID}, which is the preferred

way to set this parameter.

=item passwd

Your USPS webtools passwd, which was obtained by registering.

This will default to $Variable->{USPS_PASSWORD}, which is the

preferred way to set this parameter.

=back 4

=head2 Extended Parameters (domestic and international services)

=over 4

=item url

The URL of the USPS rate quote API. The default is $Variable->{USPS_URL}

or 'http://Production.ShippingAPIs.com/ShippingAPI.dll'.

=item modulo

Enables a rudimentary method of obtaining rate quotes for multi-box shipments.

'modulo' is a number which represents the maximum weight per box; the default

is $Variable->{USPS_MODULO}. When modulo > 0, the shipping weight will be divided

into the number of individual parcels of max. weight 'modulo' which will accommodate

the whole shipment, and the total rate will be calculated accordingly.

Example: with modulo = 10, a 34.5lbs. shipment will be calculated as 3 parcels

weighing 10lbs. each, plus one parcel weighing 4lbs. 8oz.

=back 4

=head2 Extended Parameters for domestic (U.S.) services only

=over 4

=item origin

Origin zip code. Default is $Variable->{USPS_ORIGIN} or $Variable->{UPS_ORIGIN}.

=item destination

Destination zip code. Default is $Values->{zip} or $Variable->{SHIP_DEFAULT_ZIP}.

=item container

The USPS-defined container type for the shipment. Default is

Variable->{USPS_CONTAINER} or 'None". Please see the Technical Guide to the

Domestic Rates Calculator Application Programming Interface for a complete

list of container types.

=item size

The USPS-defined package size for the shipment. Valid choices are

'REGULAR', 'LARGE', and 'OVERSIZE'. The default is $Variable->{USPS_SIZE} or

'REGULAR'. Please see the Technical Guide to the Domestic Rates Calculator

Application Programming Interface for a definition of package sizes.

=item machinable (for PARCEL service only)

Possible value are 'True' and 'False'. Indicates whether or not the shipment

qualifies for machine processing by UPS. Default is $Variable->{USPS_MACHINABLE}

or 'False". Consult the USPS service guides for more info on this subject.

=back 4

=head2 Extended parameters for International services only

=over 4

=item mailtype

The USPS-defined mail type for the shipment. Valid choices are:

package

postcards or aerogrammes

matter for the blind

envelope

Default is $Variable->{USPS_MAILTYPE} or 'package'. See the USPS international

service guides for more information on this topic.

=item country (required for international services)

Destination country. No default. You must pass the name of the country, not the ISO

code or abbreviation (i.e. 'Canada', not 'CA'). Note that USPS maintains a table of

valid country names which does not necessarily match all entries in the country

table which is distributed with the standard demo, so modifications may be needed

if you intend to use USPS international services. Consult the USPS International

Services guide for more information.
