You can change the default marketplace subdomain generated for you. Navigate to the Embed -> Settings section. As shown in the screenshot below, you can update the subdomain and custom domain to meet your requirement.

If you are using the subdomain URL there is no additional setup needed. You can immediately start using the subdomain URL ex: https://acme.apifuse.io

If you want to use a custom domain you need to have a load balancer or reverse proxy. 

  1. Update your custom domain and subdomain in the settings sections as shown below.
  2. Setup your load balancer or reverse proxy to map your custom domain with <subdomain>.apifuse.io
