# ETL: Connecting to LinkedIn
> How to create a LinkedIn Marketing connection in Integrate.io ETL and build a data pipeline to read campaign, ad, and lead generation data using OAuth.
Integrate.io ETL can access your LinkedIn data. This article details creating the LinkedIn connection and the process of building a data pipeline to read LinkedIn data in Integrate.io ETL. There are also pre-built templates to read data from LinkedIn. Please see [Create a package from a template](/etl/create-a-package-from-a-template) for instructions on using a template.
## To create a LinkedIn connection in Integrate.io ETL
Click the **Connections** icon (lightning bolt) on the top left menu.
To create a connection, click **New connection.**
Choose LinkedIn.
Click **Authenticate.** (If required, sign in to LinkedIn.)
Click **Authenticate** to authorize Integrate.io ETL access to your LinkedIn account.
In the new LinkedIn connection window, name the connection and click **Create LinkedIn connection.**
## To modify LinkedIn connections in Integrate.io ETL
Click the Connections icon (lightning bolt) on the top left menu.
Click a connection to open it and re-connect if your password has changed or the token has expired. Make any necessary changes, then click Reconnect, and Save changes. To exit the LinkedIn connection window without changes, click Back to connections (grey tab on the left side) on the LinkedIn connection window.
