A connector is the definition StackOne uses to know how to interact with a provider. Connectors are scoped to a [project](/gateway/concepts/organizations-and-projects): every project has access to all StackOne-authored connectors, while any [custom connector](/connector-building/overview) you build is available only in the project it belongs to.

These are the objects you work with on every connector:

    Reusable credentials and config — the authentication and enabled actions for a connector.
  </Card>

  <Card title="Linked Accounts" icon="link" href="/gateway/concepts/linked-accounts">
    An end-user's authenticated connection to a provider.
  </Card>

  <Card title="Actions" icon="bolt" href="/gateway/concepts/actions">
    The core unit of work an agent can perform.
  </Card>

  <Card title="Events" icon="webhook" href="/gateway/concepts/events">
    Real-time notifications from your connectors and from StackOne.
  </Card>
</CardGroup>

## Explore your connectors

The <a href="https://app.stackone.com/connectors" target="_blank">**Connectors page**</a> in the dashboard shows a summary of every connector — the actions and events available, and the profiles and accounts configured for each. Opening a particular connector also shows all logs related to it.
