AdTraction provides a SOAP API which combines the three major PPC APIs from Google, Yahoo and MSN. The API provides a normalized SOAP API over Google adwords, Yahoo Enterprise search and Bing adCenter API. A similar SEM / SMM API is provided by Kenshoo but adTraction project aims to be a better alternative by providing better synchronization and scalable report fetching functionality. This end-to-end SEM platform automates the process of building and optimizing cross channel search campaigns.
We have developed a SOAP web services server and SOAP client libraries to connect with search engine APIs.
