Target Origins {#ctp-cc-target-origin}
======================================

The [target origin](https://developer.mozilla.org/en-US/docs/Glossary/Origin "") is defined by the scheme (protocol), hostname (domain), and port number (if used).  
You must use the https:// protocol. Sub domains must also be included in the target origin.  
Any valid top-level domains, such as .com, .co.uk, and .gov.br, are supported. Wildcards are not supported.  
For example, if you are launching `Unified Checkout` on example.com, the target origin could be any of the following:

* [https://example.com](https://example.com/ "")
* [https://subdomain.example.com](https://subdomain.example.com/ "")
* [https://example.com:8080](https://example.com:8080/ "")

When you use `Unified Checkout` in an iframe, you must include the domain for the URL that loads the iframe and the iframe URL in the targetOrigins field.
