The eBay API SDK for Perl by Tim Keefer aims to simplify the programmatic interface into the eBay APIs. SDK classes include Trading API to authenticate access, Finding API to obtain eBay's next search options, Shopping API to access public eBay data, and Merchandising API to search available items on eBay considered popular among buyers. To configure the SDK information related to YAML and eBay credentials are available.
To provide more options in searching for relevant contacts, Microsoft has decided to transition WorkingWith API users to its new People API. The People API not only provides more robust metadata than the WorkingWith API, the People API includes greater browse/search functionality and ranking system.
