- First Name — The contact's first name; if empty or whitespace only, the field will be omitted from the update.
- Last Name (required) — The contact's last name.
- Type (required) — The type of contact, either Natural Person or Legal Entity.
- Additional Fields — Optional fields to update such as academic titles, addresses, bank accounts, comments, contact persons, date of birth, email addresses, favorites, fax numbers, insurance number, legal form, legal protection insurance status, legal representatives, letter salutation, name prefix, nationality, occupation, salutation, tax number, telephone numbers, and VAT identification number. Each subfield is conditionally included if provided and non-empty.
Output shape
a single updated contact record
The operation returns the updated contact data as a single record. Input fields that are empty strings or equivalent empty collections will not be sent to the API, thus not updating those fields. The contact ID is mandatory to identify which contact to update.
