Hi there!
WooCommerce core doesn’t include built-in functionality to add videos to the product gallery, whether via the admin interface or the REST API. By default, the product gallery supports images only.
Since your request involves adding custom video support through the REST API, this would require custom development, which is outside our usual scope of support.
If you’re not comfortable writing custom code, you may want to explore third-party plugins that allow product gallery videos Via rest API.
If you need more in-depth support or want to consider professional assistance for customization, I can recommend WooExperts and Codeable.io as options for getting professional help.
Alternatively, you can also ask your development questions in the WooCommerce Community Slack
Thank you
