Unable to create client id for Embed adobe pdf

When I try to create client id using https://documentservices.adobe.com/dc-integration-creation-app-cdn/main.html?api=pdf-embed-api I get an error .

I have app with http://example/netsuite where I am trying to give example as domain to create client id . When I give example.com it creates one but that doesnt work . When I tried localhost it did go thorugh but I wanted to generate one for example not example.com
