Parent : The parent page or database where the new page is inserted, represented as a JSON object with a page_id or database_id key, and the corresponding ID. (example: "{
"database_id":"{{DATABASE_ID}}"
}")
Properties : The values of the page’s properties. If the parent is a database, then the schema must match the parent database’s properties. If the parent is a page, then the only valid object key is title. (example: "{
"title":[
{
"text":{
"content":"My Page"
}
}
]
}")
