Queue a bulk domain contact update

POST /api/v2/domains/bulk/contacts

Queue an asynchronous contact update for multiple domains.

Send public dom_... IDs in domainIds and a flat contact patch object in contacts, for example contacts.email or contacts.phoneNumber.

Do not nest fields under contact roles such as contacts.registrant; this bulk route applies the same ordinary contact fields to each selected domain.

Use POST /api/v2/domains/{id}/contacts when you need role-specific registrant, admin, tech, or billing changes.

Do not use this bulk route to change a registrant personal or organisation number; that requires the per-domain contacts route plus the identity-verification/ownership flow described by GET /api/v2/domains/{id}/contacts and POST /api/v2/domains/{id}/contacts.

The API verifies every submitted domain before queuing, so a foreign or invalid ID rejects the whole batch with Problem Details.

contacts object required

Flat contact fields to apply to the selected domains. Use camelCase v2 names directly under contacts, for example contacts.email, contacts.phoneNumber, and contacts.countryCode. Do not send role wrappers such as contacts.registrant; use the per-domain contacts route for role-specific updates. registrationIdentifier is not part of this bulk operation.
