I want to create a simple domain parking service. At a mimimum I want users to be able to point their site to my parking site (parkedforgood.com). Preferably, I want to allow users to have their own customized version of the page.
I tried to use Vercel's wildcard domain and generated a specific subdomain for each users domain similar to their example. Then users could point their domain to that subdomain and it would show their specific parking page. However, I've been told that's not how it works the DNS wouldn't map from example.com to example.parkedforgood.com.
I've spent a while googling how to create a domain parking service without any real results. From what I gathered I could use Route 53 to automate the process of mapping DNS records, but even that is hard to find any info on.
What is the simplest way to create a simple domain parking service like this?
Edit: I also found this post where a comment explains that Netlify may allow you to do this via an API but I can't find any info on that either:
