# Data Library

> Connect and manage data sources for your workspace

The Data Library is where you connect external apps and files to your workspace. Each connection syncs one or more **collections** — datasets like Deals, Contacts, or Invoices — that you can use in projects.

## Add a source

1. Open **Data Library** from the sidebar.
2. Click **Add source** and choose an integration.
3. Complete the setup (OAuth, credentials, or file upload).
4. Grapple provisions the sync and discovers available collections.

You'll receive an email when the first sync succeeds.

## Manage sources

The Data Library shows each source with record counts, last updated time, and sync status.

From a source detail page you can:

* **Refresh** — trigger a manual sync
* **Toggle collections** — choose which datasets to sync
* **View schemas** — see available fields for each collection

<Info>
  Only workspace **owners** and **editors** can add and manage sources. Viewers and guests cannot access the Data Library.
</Info>

## How syncing works

1. Data syncs from your source into Grapple's warehouse.
2. Schemas are generated from your data.
3. Projects using that data re-materialize automatically.

You can't start a new sync while one is already running.

## Use data in projects

Once a source has synced, its collections are available when you create or edit projects. Use the `/map` skill in a project to join additional collections.
