It looks like you already found the answer. Thanks for coming back to share it!
I’m going to summarize it here to help anyone else looking for this info:
- The
verifiedproperty on the/v10/projects/{idOrName}/domainsadd a domain response indicates whether additional domain access verification steps are needed. - The
verificationproperty lists the TXT value needed to verify the domain for use with the project. It does not include A and CNAME record requirements for standard domain setup. - Apex domains need A records with value
76.76.21.21and subdomains need CNAME records with valuecname.vercel-dns.com(or use Vercel nameservers instead when appropriate) - The
/v6/domains/{domain}/configlets you get a domain’s configuration to check if it’s correctly configured for use with the project. Look for themisconfiguredproperty in the response.
