Dumb question: Where do I find the scripting API documentation?

I’ve done a Bing, Google, and Unity search. I’ve checked the scripting API documentation site. I cannot locate the SDK documentation for in-app purchases. I’ve found fragmented references scattered throughout a bunch of how-tos and getting starting guides but I can’t just find the straightforward, comprehensive API documentation.

I’m looking for something akin to the documentation for the AI module:

I’m sure it’s out there and I’m sure it’s easy to find.

…but I can’t find t.

Anyone know where to look?

Unfortunately, it is a bit more complicated than it should be at the moment.

The short answer is that you can find the API documented in older versions (pre-Package Manager) of the ScriptingRefrence:

The long answer is that Unity IAP has always been split into two packages: one part bundled with Unity; another that gets downloaded when you integrate the IAP Service (or download it from the Asset Store). This was to decouple the package updates from the editor’s release cycle. This is the same reason we have Package Manager now.

However, a consequence of that split is that things are a bit more complicated in transitioning it to the Package Manager world. That is the end-goal and I think there is progress toward that end, but I don’t have a timeline when it’ll be available. But at that point, the API scripting reference should be easier to find.

Thank you. That is helpful.
