PHP code to create new thread in existing forum

[jpr]

Hello,

We have a custom PHP script that was written for vBulletin 4 that I wrote within the vBulletin installation directory. It accepts a POST request and uses the Thread_FirstPost and AttachmentFiledata data managers to create a new thread in an existing forum. We have recently upgraded to vBulletin 5. Does anyone know how to code PHP, using the vBulletin 5 API to create a new thread with attachments. I can't seem to find anything and the support team was of absolutely no help whatsoever. They just pointed me to the severely lacking API documentation without any direction as to which classes I should be looking at. Any help would be greatly appreciated.

I could not find a thread that had already answered this question so I apologize is this is a duplicate, but if it is, please direct me to the thread that has already answered this question (if it exists). Thank you!
