# Update existing Notion pages with a form
> Make a form that edits existing pages from Notion, and pre-fills fields with data from the page.
## How it works
**Only share each update link with people who should see all of that page's properties.** An update link acts as a key to the entire page: anyone who opens it can view every property on the page, even properties that don't appear as questions on the form. This is what lets update forms use any page property for pre-filling, [answer piping](/answer-piping), show/hide [logic](/conditional-hiding), and [calculations](/calculations).
To keep certain properties private, store them in a separate database so they aren't part of the page being updated, or [restrict prefilled data](/update-forms#restrict-prefilled-data) so the form only loads properties mapped to questions.
Open your [Notion-connected form](https://www.fillout.com/help/notion). Click `Integrate` on the top menu followed by `Notion`.
Then specify that you want to `Update page`.
You'll now get a formula in Fillout that defines a **unique link** for every page in your table.
Create a new `formula` property in Notion and paste the formula from Fillout.
If you don’t provide an **id** in the unique URL, the form will create a new page instead.
That's it! Click `Update` on the upper right corner and `Publish` your form.
To update a Notion page, click `Preview` and select a **Record to update** or click one of the unique links from your Notion formula column.
Your form will **automatically pre-fill** the data for the record it is updating.
In Notion, the formulas with the links to update the records are most easily clickable when using a Table view.
