The Kit (formerly ConvertKit) connector syncs your email marketing data – subscribers, broadcasts, forms, sequences, tags, custom fields, purchases, and email templates – into PostHog.

## Adding a data source

1.  Go to the [sources tab](https://app.posthog.com/data-management/sources) of the data pipeline section in PostHog.
2.  Click **\+ New source** and then click **Link** next to ConvertKit.
3.  Next, you need a v4 API key from Kit. You can create one in your [Kit account settings](https://app.kit.com/account_settings/developer_settings) under developer settings. Copy the API key value (it starts with `kit_`).
4.  Back in PostHog, enter the credentials and click **Next**.
5.  Select the tables you want to sync, set the sync method and frequency, then click **Import**.

Once the syncs are complete, you can start using Kit data in PostHog.
