This is a simple Python wrapper for the USPS API. Instead of having to deal with XML, use this library and receive nicely formatted JSON back while tracking shipments, creating shipments, and validating addresses.


Installation

To install usps-api, use pip::

pip install usps-api

Or to install from source::

python setup.py install

Configuration

Note: In order to use any of these APIs, you need to register with USPS and get a USERID https://www.usps.com/business/web-tools-apis/welcome.htm. For the create_shipment endpoint, you will also need to request further permissions by emailing uspstechnicalsupport@mailps.custhelp.com about Label API access.


Usage

Track Shipments

.. code-block:: python

from usps import USPSApi

usps = USPSApi('XXXXXXXXXXXX')
track = usps.track('00000000000000000000')
print(track.result)

Create Shipment

The create_shipment function needs a to and from address, weight (in ounces), service type and label type. Service types and lable types can be found in usps/constants.py. Defaults are SERVICE_PRIORITY and LABEL_ZPL.

.. code-block:: python

from usps import USPSApi, Address
from usps import SERVICE_PRIORITY, LABEL_ZPL

to_address = Address(
    name='Tobin Brown',
    address_1='1234 Test Ave.',
    city='Test',
    state='NE',
    zipcode='55555'
)

from_address = Address(
    name='Tobin Brown',
    address_1='1234 Test Ave.',
    city='Test',
    state='NE',
    zipcode='55555'
)
weight = 12  # weight in ounces

usps = USPSApi('XXXXXXXXXXXX', test=True)
label = usps.create_label(to_address, from_address, weight, SERVICE_PRIORITY, LABEL_ZPL)
print(label.result)

Validate Address

.. code-block:: python

from usps import USPSApi, Address

address = Address(
    name='Tobin Brown',
    address_1='1234 Test Ave.',
    city='Test',
    state='NE',
    zipcode='55555'
)
usps = USPSApi('XXXXXXXXXXXX', test=True)
validation = usps.validate_address(address)
print(validation.result)
