Manual domain verification for Supabase-hosted callback domain (supabase.co)

App Marketplace Domain Validation
1

Hi Marketplace team,

I’m preparing a General app (user-level OAuth, single scope) for submission. My legal-documents domain is already verified, but domain verification is also asking me to verify the domain of my managed backend provider (Supabase), where my OAuth callback and deauthorization endpoints are hosted. I control my own project subdomain there, but I can’t add a TXT/HTML/meta record to the provider’s shared apex domain, which I don’t own — so I can’t self-verify it.

Could a specialist advise on completing manual verification for a backend-provider-hosted callback domain? I’m happy to share the specific subdomain, endpoint URLs, and my app ID privately. Thank you!
