If you're setting up the Clipchamp API, have successfully embedded a Clipchamp button on your website but are seeing a button text of "unavailable" when you click it, there is a high chance that you haven't set your production domain in the API settings yet.
To get the button to work, go to the API settings at clipchamp.com/api-settings, go to Production Website Domain and enter the URL of the website where you want to embed the button.
After entering the production domain, click the Apply Changed Settings button.
In this example, the production domain is clipchamp.com. Make sure to enter the production domain of your own website. Our sample embedded Clipchamp button can be seen at https://clipchamp.com/blog/2016/new-clipchamp-video-sharing-plugin-wordpress/
Please contact us at firstname.lastname@example.org if the button on your website still does not appear after you entered and saved the production domain.
