WhatsApp Cloud API - Block API | Developer Documentation

ChatArchitect availability: WhatsApp blocking and unblocking are not supported. ChatArchitect does not provide these actions through its API or ready-made integrations. Read the customer availability guide before using the technical Meta Block API reference retained below.

A local CRM restriction or exclusion from an audience does not establish that the contact is blocked in WhatsApp. Meta endpoints, credentials and response examples below belong to a separate direct Meta implementation; they cannot be used as ChatArchitect requests by replacing a Bearer token with App key and Secret. The reference is retained for context, without asserting current endpoint parameters or availability through ChatArchitect.
