I recently integrated our emailing solution with Cloudflare for SaaS and noticed that Cloudflare’s API documentation specifies that endpoints relating to Custom hostnames are categorized as
Enterprise only (see screenshot below):
I was a bit worried when figuring this out, as Cloudflare for SaaS was made available to all plans about a year ago (see annoucement). It includes general availability for free plan according to the blogpost.
So I made some dummy requests with my free plan and turns out that those endpoints are available with a free plan. So, I assume it just a frontend issue with the API documentation. I hope so at least, because it’s a must-have to be able to query the API. The whole point of vanity domains is that customer can self-serve.
