application/jsonemailstringRequiredContact 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.
jan@barasek.comsourcestringOptionalSignup source identifier for analytics.
webfootersocialgroupsstring[]OptionalNewsletter group tags to assign to the contact.
phonestringOptionalContact phone number in international (national) format.
Preferred format: +<country_code> <local_number>
- Leading plus sign (
+) is required - Followed by the country calling code (e.g.
420) - One space after the country code
- Full local number without spaces
Example: +420 777123456
This format ensures unambiguous storage, validation, and compatibility with SMS, calling, and third-party integrations (e.g. Twilio, WhatsApp, CRM systems).
