SuiteCRM 8.4 Developer API Access?

Can someone point me to the information needed to properly setup Postman so I can start developing a special project? There seems to be v4, v8, and now another API which I can’f find.

I just want to be able to create a new account when someone signs up on another site.

The new API is a GraphQL API. If you search these forums for it, there are a few posts with instructions. But overall, it’s not very documented yet.

The only thing that might be helpful is that the entire v8 UI runs on top of that API, so the v8 code is full of examples of how to use it.
