/bff/contact/create

Creates a single contact from a minimal form. Either email OR phone is required (both are allowed). First name, last name and IČO are optional. When IČO is provided, the company name and address are auto-filled from ARES. Optionally triggers the registration workflow with the standard confirmation e-mail (requires email).

Parameters

JSON body

Request body

application/json

emailstringOptional

Contact email address.

The system validates the input as a standard email address and automatically applies normalization and canonicalization.

All API responses return the normalized form, and each email address is unique per organisation within the system.

Phone-only contacts: Since 2026-06-10 a contact may exist without an e-mail when it was registered only by phone (e.g. imports of phone-only records). Responses that expose such contacts use API_EMAIL_NULLABLE instead, where this field can be null. Endpoints that accept e-mail as input still require a valid value here — phone-only creation goes through admin-only import / BFF flows.
