Seller type on seller information

Changes to the API since 042.

Added

The seller information endpoint now accepts an optional sellerType field.

This field identifies the legal category of the seller and accepts one of the following values: INDIVIDUAL, HOUSING_COOPERATIVE, DEVELOPER, ESTATE, LEGAL_GUARDIAN, or ORGANISATION.

The field is optional — existing integrations that omit it continue to work unchanged.

How does Hemnet differentiate seller information and billing information?

These are two separate write-only endpoints on every listing:

• Seller information (PUT /listings/{id}/seller_information) captures the identity of the seller — their name, email address, and personal or organisation ID number. Hemnet stores this for internal identification purposes and it cannot be retrieved after submission.
• Billing information (PUT /listings/{id}/billing_information) captures where to send invoices — a recipient name and postal address. The invoice recipient is not necessarily the seller: for example, a housing cooperative (HOUSING_COOPERATIVE) may be the seller while invoices go to the brokerage firm.

sellerType belongs to seller information because it describes the legal category of the seller, not the billing recipient.
