# Frequently asked questions

## User management

<AccordionGroup>

  </Accordion>

  <Accordion title="Does the Notion API support SSO using SAML?">

## Connections

<AccordionGroup>
  <Accordion title="Why can't I access an installation access token?">
    Confirm that you are an admin in the workspace where the connection was created. You can check inside Notion via `Settings & Members` in the left sidebar. If you're not an admin in any of your workspaces, you can create a personal workspace for free. If your workflow should act as your own Notion user, consider using a [personal access token](/guides/get-started/personal-access-tokens) instead.

## Databases

<AccordionGroup>
  <Accordion title="Why are relation page property values empty?">
    Double check to see that your connection has been shared with the database the [relation property](/reference/database) points to — This should fix it! If you're still seeing unexpected results, reach out for [help](/page/).
  </Accordion>

  <Accordion title="Why are relation page property values empty?">
    Double check to see that your connection has been shared with the database the [relation property](/reference/database) points to — This should fix it! If you're still seeing unexpected results, reach out for [help](/page/).
  </Accordion>

  <Accordion title="When querying a database, is it possible to display the page titles of related pages rather than just the ID?">
    You have two options:

    1. Add a rollup property to the database which uses a formula to get the related page's title. This works well if you have access to updating the database's schema.
    2. Otherwise, [retrieve the individual related pages](/reference/retrieve-a-page) using each page ID.
  </Accordion>

  <Accordion title="Are there limitations on the number of requests that can be made per second?">
    Yes, the API has [rate limits](/reference/request-limits#rate-limits). Your connection can gracefully handle these limits by slowing down when the API responds with a HTTP status 429 or 529.
  </Accordion>

  <Accordion title="How do database property type changes work in the update database endpoint?">
    All properties in pages are stored as rich text. Notion will convert that rich text based on the types defined in a database's schema. So when a type is changed both in the Notion and in the API, the data will continue to be available, it is just presented differently.

    For example, a multi select property value is represented as a comma-separated list of strings (eg. "1, 2, 3") and a people property value is represented as a comma-separated list of IDs. These are compatible and the type can be converted.

    Note that not all type changes work. In some cases data will no longer be returned, such as people type → file type.
  </Accordion>

## API limitations

<AccordionGroup>
  <Accordion title="How can I upload files?">
    Use the [file upload API](/guides/data-apis/working-with-files-and-media) to upload files such as images and PDFs to your workspace. [Notion MCP](/guides/mcp/overview) does not currently support file uploads.
  </Accordion>

  <Accordion title="Does the API support filtering users by their email and/or name?">
    Not currently, but we're open to your feedback on this. [Get in touch](/page/) and tell us a little more about your problem.
  </Accordion>
</AccordionGroup>

<Accordion title="I have a different question">
  If you have a programming question, like in a specific programming language or framework, you can ask on [StackOverflow](https://stackoverflow.com/questions/tagged/notion-api). Use the tag `notion-api` so the rest of the community can help answer your question.
