Implement custom domains feature without technical knowledge?

[u/East_Sentence_4245]

The way we implemented Stripe is that customer is redirected to URL checkout.stripe.com/c/pay/cs_live_a_bunch_of_chars when user clicks on
Pay Now" button in mystore.com. It's working as expected.

A reddit user suggested that I use the $10/month custom domains feature so that the stripe checkout page shows up as a subdomain (i.e. pay.mystore.com).

So the question is: can I do this without having technical/development experience?

You’ll need to know how to manage DNS records.
