Availability of Archicad APIs for Older Versions (AC20 and Earlier?)

[til0byte]

Hi everyone,
Quick question about API support across versions:

I’m looking at the Archicad APIs and trying to figure out how far back they go. The oldest API I could find in the official resources is for Archicad 24. Are there official APIs available for older versions – specifically Archicad 20? If so, where can I find them?

Thanks!

I think the API started at about Archicad 6. I still have disks with older API versions, but I think they're not likely to be online – there's no practical use for them. Running old software becomes increasingly difficult over time because hardware and operating systems eventually make them unviable. And for old APIs you would also need older compilers etc., so it's much harder than just having the Archicad API.

But I can dig up an old version for you if you really want it.

Yes, the original API appeared with Archicad 6.0, it was version 1.3 🙂

We haven't published the earlier versions; I'm curious why you need that...

Best, Akos
