Hi, I am new to Cloudflare. I use Namecheap for my nameserver, I see that I am asked to move the DNS. Also, it says it will take 24 hours. If I set up nameserver to Cloudflare will this interrupt my service to my user? I am worried to move to Cloudflare’s nameservers.

Before you move to Cloudflare’s name servers, you need to make sure all your DNS records are here, just like they are at Namecheap. And make sure any mail-related DNS entries are set to DNS Only, as Cloudflare does not proxy email.
If all your DNS records match, there will be no interruption during the transition.
If you’re going to use a hostname not covered by Cloudflare SSL, you’d have to use ACM. Personally, I advise you to not use the ‘www’ subdomain in front of another subdomain. Just go with stickycart. Then you won’t have the SSL problem.
Create advice already said before… One thing I wanted to add was that when you do go to move DNS, FIRST update your TTL’s on your current registrar forr ALL dns settings to their minimum values. If you can do 60 seconds, great, al low as possible. THEN, when it’s time, update your nameservers to Cloudflare’s, Then, AND DON’T SKIP THIS STEP, go into your CF dash, go to DNS for the domain in question, and click the “Check Nameservers” button.
Most of the time Cloudflare will automatically monitor for DNS updates, but sometimes this doesn’t happen, then you have downtime to deal with while DNS propagates.
