SAPO messenger is introducing an API to allow developers to create plugins for their instant messaging client. The API is based on XMPP and allows plugins to be created using languages like Delphi, Javascript, and VBScript. Developers can access roster and presence information and be notified of changes. Example uses provided include social networking integrations and displaying notifications. Developers are encouraged to contact SAPO to discuss their plugin ideas.
