You need to setup a CNAME record. See our docs: https://docs.railway.com/guides/public-networking

Go daddy ask me for CNAME & IP address

Is that necessary

I only got the CNAME

This depends on the domain being a root (domain.com) or subdomain (example.domain.com)

Godaddy does not support cname flattening; you may need to use cloudflare to handle DNS for you: https://docs.railway.com/guides/public-networking#adding-a-custom-domain -> search for "godaddy"

is there any option to contact u directly to guide me ?

Im on it for 3 days

I will very appreciate it.

thanks

Hey eyalyehiely, everything you need can be found in the public networking documentation that itsrems linked above.

Here are the steps necessarily to add your root/apex domain with GoDaddy:

1. Change your domain's nameservers to Cloudflare's by adding your domain to Cloudflare (you will need a Cloudflare account, create one if you haven't already). Cloudflare's docs regarding this: https://developers.cloudflare.com/dns/zone-setups/full-setup/setup/.
2. Add the root/apex domain to the desired Railway service and add the requested CNAME record for your root/apex domain via Cloudflare.
3. If you have enabled Cloudflare's proxy, change the SSL/TLS settings to Full. Railway's docs regarding this: https://docs.railway.com/guides/public-networking#provider-specific-instructions.
