The third party UBBWiki
is our documentation resource, and UBBDev
is our third party modification resource (both owned by myself, a contracted developer for UBB.threads), though note that any modifications to your base system is unsupported by the vendor (UBBSystems).
The UBB.threads software does not have an API that you can tie into; however, there is the User Authentication Class
which allows for a PHP bridge into the software.
