# Sample Use Cases & Flows: Domain DNS

This article shares a possible use case your implementation could support, as
well as a sample flow. You're not limited to this use case, but it can be a
helpful jumping off point for your planning.

## Update DNS records for a domain

You can update the MX and TXT records for a domain purchased through Wix, and connect it to an external (non-Wix) site.

To update the DNS records for a domain:

1. Prompt the site owner for the relevant domain name, DNS record type, and host name of the registered domain. 
1. Call [Update DNS Zone](https://dev.wix.com/docs/rest/account-level/domains/domain-dns/update-dns-zone.md)
   to change the MX and TXT records in Google's Cloud DNS.
1. Connect the domain to the external site.

## Connect an external domain by nameservers to a Wix site

You could help Wix site owners connect an external domain by nameservers to
their site. Note that you can't use
[Update DNS Zone](https://dev.wix.com/docs/rest/account-level/domains/domain-dns/update-dns-zone.md)
for external domains that are connected by pointing.

To connect an external domain by nameservers to a Wix site:

1. If the relevant site is a free Wix site, call
   [Resellers Create Package v2](https://dev.wix.com/docs/api-reference/account-level/resellers/packages-and-product-instances/create-package-v2.md)
   to assign a Premium plan to it.
1. Register the domain through an external provider.
1. Call [Create Connected Domain](https://dev.wix.com/docs/api-reference/account-level/domains/connected-domains/connected-domain-v1/create-connected-domain.md)
   to start the connection process. Make sure to use
   `{"connectionType": "NAMESERVERS"}`.
1. Call [Get Connected Domain Setup Info](https://dev.wix.com/docs/api-reference/account-level/domains/connected-domains/connected-domain-setup-info-v1/connected-domain-setup-info-object.md)
   to retrieve the new DNS record values. You find them in
   `connectedDomainSetupInfo.pointingRecords.aRecord.values`
   and `connectedDomainSetupInfo.pointingRecords.cnameRecord.value`.
1. Call [Update DNS Zone](https://dev.wix.com/docs/rest/account-level/domains/domain-dns/update-dns-zone.md)
   to change the A and CNAME records in Google's Cloud DNS.
1. Call [Get Connected Domain](https://dev.wix.com/docs/api-reference/account-level/domains/connected-domains/connected-domain-v1/get-connected-domain.md)
   to monitor the connected domain's `dnsPropagationStatus` and confirm that it
   changes to `"COMPLETED"`.
