Creating a thread in our forum from outside vBulletin

[SNease001]

I've been searching (unsuccessfully) for an example of creating a thread inside our forum using the API newthread_postthread method. I need to do this from outside vBulletin.

Basically, we have a custom web portal where our clients can review their submitted cases and I need to provide the ability for them to create a new forum thread from within that portal/case screen. The portal is not written in PHP but is rather a combo of ASP & .Net. I have developed other API calls from within it (FedEx, Avalara, etc) by posting a JSON-based request and parsing a JSON-based response. Since vBulletin's API shows to return JSON responses, I'm guessing I would POST a JSON request but can't find any examples. Any help would be greatly appreciated!!!!!!
