Instead, you should convert your markdown into an array of Notion-compatible blocks (e.g., headings, paragraphs, lists) and insert them as the children of the Notion page.
This approach avoids the character limit and preserves your markdown structure.
You can use the community node `n8n-nodes-notion-markdown` to help with this conversion, and then send the resulting array as the children property in your Notion API request or Notion node in n8n.
