Finding the right hook(s) for plugin(s) in vBulletin 5.2.0

[robertw795]

I am currently adding advertisements to a forum and I want to place an advertisement after every 5 posts in a thread. To do this I have to write a custom plug-in.

I used to have a similar custom plug-in in a vBulletin 3.8.5 forum which I wanted to use as a reference. I noticed that the hooks have changed over the years. At this point my problem is that I don't know what hook I have to use for my plug-in, as the hooks of 3.8.5 don't correspond to those of 5.2.0 anymore.

I'd like to ask you which hook I have to use for my plug-in. And in general, where to find documentation about hooks and their functionality for future reference.

Where can I find this?

Thanks in advance.
