Verify Domain

New payment addresses need a callback URL on a verified domain. Verify the domain your callback URLs use here, once per domain. Addresses you already created keep working.

Verifying example.com by DNS also covers its subdomains, such as api.example.com. Verifying by HTTPS file covers that exact host only.A subdomain that is a CNAME can't hold a TXT record, so verify its parent domain instead.Shared hosting domains, such as up.railway.app or herokuapp.com, can't be verified. Enter your app's own host instead, such as myapp.up.railway.app, and verify it with the HTTPS file.IP addresses can't be verified here, please contact support.
