lookups for categoryId, contentGroupId and contentTypeCategory

I am looking at the blogs API. I am seeing that I get blogs back with the following values:

“categoryId”: 3, 10 “contentGroupId”: “4580836351”, 11 “contentTypeCategory”: 3,

I would like to know if there are API methods for either getting all of these values or getting them individually, something like:
https://api.hubapi.com/cms/v3/blogs/categoryIds?hapikey=key

Have you checked out the legacy docs?

There are a couple endpoints that may help

https://legacydocs.hubspot.com/docs/methods/blogv2/get_blogs

this was helpful. It turns out contentGroupId is same as blog Id. I can get a list of blogs by using the V2 Get Blogs endpoint.
I would still like to know what the categoryId and contentTypeCategory refer to, but the above may be enough for my immediate purposes. Going to accept as solution for that reason.
