Inputs
- phoneNumberId (required) — The connected Kapso WhatsApp number (chosen from a list or set via expression) that will block the users.
- blockedUsers (required) — Repeatable list of users to block. Each entry has a User Phone field in phone mode: 8–15 digits, no plus sign or spaces (e.g. 15551234567).

The exact response fields are not defined in the provided source summary. Invalid phone numbers (not 8–15 digits) are rejected by validation before the request is sent.
Examples

Add multiple User entries, with each phone set via an expression such as {{ $json.phone }}.
