-Custom Domain is a fully-managed service that enables you to configure a first-party subdomain over HTTPS to track event requests through your domain (for example, cdp.mydomain.com), instead of tracking events through Segment's default domain (segment.com). Tracking events through your domain lets you reclaim some of the first-party data lost to end user ad-blockers and browser privacy controls that block Segment's default domain. With more complete first-party data comes a more complete view of your customer's behaviors, and can lead to more robust profiles, more accurate attribution, and, ultimately, greater ROAS.

 ### What sources can I use with Custom Domain?
-Custom Domain was largely developed to support JavaScript sources. It helps with comprehensive data collection from your website when accessed over any platform (desktop, mobile, and more). You can use the subdomain for all other non-JavaScript sources as well, for consistency, but it will have no impact on data collection for those sources.

 Once Custom Domain is enabled for your workspace, the Segment app generates a new JavaScript source code snippet for you to copy-paste into the header of your website. For non-JavaScript sources, you can use the sub-domain as an endpoint when using the Tracking API.
