Unable to create note- getting 404 error

Hi,

I've mostly managed to navigate the Intercom API without issues. However, I'm struggling to create a note. (I'm using Python, but can replicate the issue with curl.)

curl https://api.intercom.io/contacts/5f908d5b37fbb4bceed4c97a/note-X POST -H 'Authorization:Bearer *snip*' -H 'Accept:application/json' -d 

{

 "body": "Shiny",

 "admin_id": "*snip*"

}

And I get a 404. Basically, https://api.intercom.io/contacts/lt;intercomid>/note doesn't seem to exist.

If I change the URL to https://api.intercom.io/contacts/lt;intercomid>/notes then I get a different error - 400, "Body can't be nil"

I am on the latest version (2.3) of the API.

Can anyone help please?

Thanks

Robert
