The Pingen API allows sending postal letters online. Pingen is a web-based Hybrid Mail service that provides print, package, stamp, and post services. Recipients can receive letters in the mail from their senders who can validate documents, print envelopes, and track and trace their mail from Pingen.
The following is a list of sample source code snippets that matched your search term. Source code snippets are chunks of source code that were found out on the Web that you can cut and paste into your own source code. Whereas most of the sample source code we've curated for our directory is for consuming APIs, we occasionally find something interesting on the API provider side of things. If you know of some sample source code that would be of interest to the ProgrammableWeb community, we'd like to know about it. Be sure to check our guidelines for making contributions to ProgrammableWeb.
