The General API Development Kit enables software developers to extend the functionality of Archicad.

The following documents give a short overview of the possibilities and requirements.

Add-ons built with this API version are compatible with Archicad 27. You can check what improvements and corrections have been made to the former API versions.

Note, that because of the interface changes significantly release by release, we do not ensure neither interface nor binary compatibility with previous versions. So add-ons compiled with older DevKits cannot be loaded in the Archicad 27.

The following documents contain detailed information on different aspects of API development. Please consider these rules and recommendations in order to develop solutions conforming to Archicad.
