Can't publish blogpost through the API

Whenever I try to publish a blogpost through the API (

https://api.hubapi.com/cms/v3/blogs/posts/schedule

) I get an error message. It says that the content scope is restricted and that the user doesn’t have the rights to publish the blogpost. I am however able to edit the blogposts content through the API. I was wondering if someone could help me figure out why this specific call won’t work.

@STadema does this have something to do with the HubSpot API sunsetting? A lot of folks are talking about it, so that would be first guess.
