## Business Verification / API

### Added International Business Verification

Middesk verifies businesses registered outside the United States and returns their registrations in the same format used for US Secretary of State data. Add an `international_business_verification` order when you create a business, optionally supply known registration numbers in the `registrations` array, and use `POST /v1/businesses/{id}/registrations` to add a registration to an existing business. Available to accounts with International Business Verification enabled. [View the international verification guide](/verify-business/international).

### Changed the registration object for international registrations

The registration object now includes `country_code`, `jurisdiction_details`, and `submitted`. For international registrations, `jurisdiction` can return `HOME`, `EXTRA_PROVINCIAL`, `UNKNOWN`, or `null` in addition to `DOMESTIC` and `FOREIGN`; `state`, `source`, `entity_type`, `registered_agent`, and `registration_date` can also be `null`. Confirm your integration tolerates null values on these fields. US registrations are unchanged. [View the Registration object reference](/reference/registration).

## Credit Risk / API

### Clarified the collateral contract for lien filing

Lien filing requests take `collateral` as a string describing the assets that secure the lien. `collateral_type` is a categorization Middesk returns on the lien object, not a request input. The lien filing and lien search guides now show the string form and list the `collateral_type` values returned in responses. [View the lien filing guide](/assess-risk/file-lien).
