The Lotus C application programming interface (API) used to be the only way early Notes adopters could accomplish any function beyond
what formula language provided. Today, Notes/Domino developers have many programming language choices, and all of the languages are much
more capable than early formula language — but there are still compelling reasons at times to use the Lotus C API. For the occasions when
you need the fastest performance possible, capabilities not offered by any other language, or hooks to insert actions into processing events or run programs outside of Notes/Domino, your best programming option is the Lotus C API.
