I’m using v3 CMS API with OAuth [Accounts Dashboard | HubSpot](https://developers.hubspot.com/docs/api/cms/blog-post)

to create a blog spot and I’m getting error 400 PARENT\_BLOG\_DOES\_NOT\_EXIST, “Selected parent blog doesn’t exist”.  
The blog ID is correct (copied from “Get posts”), the OAuth token is correct (works for other API).  
I used the testing tool on the API documentation webpage, with the same error. So the problem should not be in the format of the post.

Does anyone know what parameters are required for payload?  
Does it work for anyone or is it a bug on the API side?

It seems the problem was fixed. I can now create new blog posts.

I have been having this issue as well. Have copied settings exactly and always getting

## PARENT\_BLOG\_DOES\_NOT\_EXIST

Each attempt returned:

```auto
jsonCopyEdit{ "errorType": "PARENT_BLOG_DOES_NOT_EXIST", "message": "Selected parent blog doesn't exist"
}

```

- We’re using a Private App token with the content scope enabled (confirmed in the UI).

- I am a Super Admin in our portal.

- Subscription includes Content Hub Professional.

- Token works for GET operations to the same endpoint.
