Box API usage with custom domain


My team has a custom domain enabled for our Box account, such that when we access Box, the domain is https://{company_name}
I am now trying to create a feature to programmatically generate an embed link for files in our company’s Box storage.

However, as far as I can tell, this is only shown with the default API URL ( Given that we use a custom domain, what would the API URL be to get the shared link of a file?
