question

Hi @vandanaRatnaparkhi-8204,

Using onenote-post-notebooks, we can create notebooks and they will be stored directly in users OneDrive and can be accessed using onenote.
Here is an example snippet,

 GraphServiceClient graphClient = new GraphServiceClient( authProvider );
    
 var notebook = new Notebook
 {
  DisplayName = "My Private notebook"
 };
    
 await graphClient.Me.Onenote.Notebooks
  .Request()
  .AddAsync(notebook);

If the query is regarding sticky notes(can only be found in users mailbox https://outlook.office.com/mail/notes) currently is not supported from Microsoft Graph API.

Hope this helps.
