Stamps.com is an online postage vendor that also provides a SOAP-based API for generating USPS shipping labels. Users can make and print labels themselves or e-mail labels to customers for printing. The API also supports address cleansing, calculating USPS rates, package tracking, and more. These services are recommended for integration with web-based e-commerce systems or other web-hosted applications.
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.
