Hello, I know it is possible to get the user id of a user: https://community.graphisoft.com/t5/Developer-Insights/Introducing-new-user-identification-to-the-API-of-Archicad-26/ba-p/588853?utm_source=chatgpt.com But is it possible to verify it? Let's say I make an Add-on that...

An author of a GDL object might want to sell it while also preventing buyers from sharing it with others. How is it done? A GDL object cannot make HTTP requests and, to my knowledge, does not have access to any crypto libraries. I have some ideas, but there may exist simpler...

Hi Given the nth character in a text element, is it possible to easily get that characters position in world coordinates? It could probably be calculated from a combination of API_TextType, API_ParagraphType and maybe API_FontType but it would be tricky to cover every case. ...

Hi There Is it possible through the C++ API to open for example the building materials attribute dialog from an Add-On and programatically search for a material? -Benjamin

Lets say you have coded an Add-On that you want to sell. In that case you probably need some licensing solution. Does GRAPHISOFT provide any help with this? For example some way to associate your Add-On license with an Archicad license. One idea that does not involve GRAPHIS...

Thanks for the links and context. Alright, yes I know you can inject data through parameters. But it feels complicated for a license as there are no crypto functions in GDL. A "license checker" Add-On could do the license check and write "is_valid=true" to a parameter but th...

Before you could make specific GDL add-ons in C++: https://archicadapi.graphisoft.com/downloads/gdl-development-kit So you could maybe have created a GDL add-on for license checking (using a C++ RSA library) with the public key of the license server embedded. Perhaps you cou...

Hello Bernd, thanks for sharing your solution. Yes that idea is better. I guess you'd have to decompile/recompile the add-on and remove function calls to circumvent that license check, or perhaps replace the embedded public key. Feels way harder compared to extracting a secr...

BenjiDev

Thanks, something like: Add-On sends: GSID, timetamp, HASH(GSID + timetamp + embedded secret key) Server calculates the same hash with provided GSID, timestamp and internal secret key and checks that the hash provided by the Add-On matches, also checks that the timestamp is ...

Yeah, but a legitimate user could use different devices with the same account. So the server cannot know that an unrecognized device ID for a specific Graphisoft user ID is illegitimate or not.
