Package: pyPostal
pyPostal is an Interface for sending real (paper-based) letters via an API.There are several providers which offer printing, envelope stuffing and posting services but currently onlyhttps://www.pixelletter.de/provides such services to SME without contractual hassles and the like.This interface only supports mailing PDFs which have the Address Placed in the PDF at theDIN 5008Address Location.You can download it at thePython PAckage Index (PyPI).High-Level UsageUsage is very easy: Just set up your credentials in the Environment before starting Python:export PYPOSTAL_PIXELLETTER_CRED='your@email.com:PASSWORD'Then callpypostal.send_post_pixelletter()with the open PDF files or PDF datatream to send and the country code of the recipient:>>> import pypostal
>>> pypostal.send_post_pixelletter(
        [open('/Users/md/Desktop/Testbrief.pdf').read()], 'DE')If you prefer to hardcode credentials you can provide them via a function call instead via the environment:>>> pypostal.send_post_pixelletter([open('Testbrief.pdf')], 'DE',
                                   username='your@email.com',
                                   password='PASSWORD')Pixelletter InterfacePixelletter offers aBunch of Documentationand aPHP Library. Unfortunately there is no specification of the HTTP-API and the documentation seems also somewhat incomplete and outdated. Also it seems that Pixelletter uses no prebuild XML processing and parsing pipeline but build one arround print statements. This library was build by using trial and error and reverse engeneering the website.Example UsageThe Pixelletter interface is straightforward:# Log in
>>> from pypostal import Pixelletter
>>> pix = Pixelletter('your_email', 'your_password', test_mode=True)

# Show how many Cents Pixelletter owes you.
>>> print pix.get_account_info()['customer_credit']
1995

# Send two PDFs from your Desktop as en Letter
>>> print pix.sendPost([open('/Users/md/Desktop/Testbrief.pdf'),
                        open('/Users/md/Desktop/Thesis.pdf')])

# Send one PDF printet in color and in CO2 neutral fashion.
>>> print pix.sendPost([open('/Users/md/Desktop/Testbrief.pdf').read()],
                       guid='0815-4711', service=['green', 'color'])You can provide a GUID (“Transaction Identifier” in the Pixelletter Documenttion) - this might support a Track and Trace Interface but I havn’t seen any documentation on this. Something likehttps://www.pixelletter.de/de/auftraege.phpas anAtom Feedvertainly would be nice.The Python library currently supports following services:green (default, useservice=[]to disable)einschreiben (seeDHL / Deutsche Post AGon the differences)einschreibeneinwurfeigenhaendigeigenhaendigrueckscheinrueckscheincolorThe Pixelletter API also seems to support “Nachnahme”, “Postident Comfort” and “Ueberweisungsvordruck” but they are undocumented and currently not supported by this library.Sipgate.de Fax InterfaceSipgate.de offers a hot and new REST API withsome documentation. Pypostal provides functionality to send PDFs via Fax.Example UsageA nice and clean interface:# Log in
>>> from pypostal.sipgate import Sipgate
>>> sip = Sipgate('your_email', 'your_password')

# Send a PDF via Fax
>>> sip.sendFax([open('/Users/md/Desktop/Testbrief.pdf')], 'sender_number', ['dest_number'])Planned other InterfacesWe want to supportPixelletter Fax interfacePawisda L-Vin Post / Pinbriefportal SOAP InterfaceLinksWWW::Pixelletter(Perl Module) for PixelletterPHP Libraryfor PixelletterPixelletter DocumentationpyJasperandiReportare a decent way to generate PDFs.
