REST API for Blog-Post Content

Hi,

I’m trying to extract blog-post’s content (both plain and rich text) with no success.
Following this section in the documentation, ‘contentId’ is the only related field returned in the response.
Both requests return the same response:

https://www.wixapis.com/blog/v3/posts/<post-id>
https://www.wixapis.com/blog/v3/posts/<post-id>?fieldsToInclude=[contentText]

As you can see below - no content what so ever
Thank you

The response:

Have you tried CONTENT_TEXT instead?

Found the solution - the documentation need to be fixed

fieldsToInclude must specify single value to fetch.
for instance

These return the required fields
https://www.wixapis.com/blog/v3/posts/?fieldsToInclude=RICH_CONTENT
https://www.wixapis.com/blog/v3/posts/ ?fieldsToInclude=CONTENT

These do not return the requested fields
https://www.wixapis.com/blog/v3/posts/ ?fieldsToInclude=RICH_CONTENT,CONTENT
https://www.wixapis.com/blog/v3/posts/ ?fieldsToInclude=[RICH_CONTENT,CONTENT]
