An enterprise system may include a server including an integration module that enables applications at the server to integrate web services, e.g., by providing links to the external web service. Each application is associated with one or more business types in a table at the server. The integration module, which may be an API, sends a list of external web services of a type (or types) associated with an application when a user at a client computer in the enterprise system opens that application. The integration module may also generate a URL call and redirect the user's browser to an external web service when the user selects that external web service.
