Your credential needs domains:contacts. Resolve the current domain identifier, read its contacts and check the TLD's current requirements. Confirm the owner has approved any registrant identity change and understands any verification or transfer-lock consequence.

The current connector uses role objects with fields such as first_name, last_name, company_name, email, phone_e164, address1, city, state, postal_code and country_code. Use the roles and mandatory values accepted for that domain.

This illustrates the payload shape, not a substitute for the customer's real contact details or the registry's complete requirements. Do not copy sample identities into a live registration.

1. Submit the reviewed JSON using the authentication helper and a stored idempotency key.
2. Retain the operation reference and inspect its final status.
3. Complete any registrar verification requested through the approved process.
4. Read the assigned contacts again and compare the accepted values with the intended change.

Updating a reusable contact profile alone does not necessarily change a registered domain. Conversely, changing the registrant for one domain should not be treated as permission to replace every customer's contact profile.

For multiple domains, use a reviewed portfolio workflow and account for different registry requirements. Avoid a bulk replacement that erases technical or billing roles the owner intended to retain.

Read validation errors for the specific field or role. For a timeout or pending state, inspect the original operation before retrying. Keep personal data out of support logs; provide the operation reference and redacted field names unless an approved support channel requires more detail.
