Abstract: The communication bridge enables trading partner customers to mass customize their interactions with their affiliated trading partners by controlling workflow and data presentation. A method and system allows the integration of standard and proprietary content, such as data and “look-and-feel” elements, from trading partners to be presented via a standard interface for the purpose of conducting mass customized interactions (transactions, communications). There is a high degree of variability in screen and workflow presentation. A particular Application Programming Interface (API) facilitates the dynamic exchange of information between disparate trading partners and end users.
