Shared Blocklist with Automatic STOP and START Handling

Manage one WhatsApp blocklist across automations and the Team Inbox. Customers who reply STOP are opted out, and START opts them back in.

Applies to: WhatFlow Business API, the official Meta Cloud API app

What's new

  • One blocklist for automations, broadcasts and the Team Inbox.
  • Replying STOP opts a customer out and START opts them back in, automatically.
  • Keyword chips and a clear save bar make the blocklist easy to manage from the dashboard.
  • Blocklist enforcement is off by default, so you choose when to turn it on.
  • The template editor explains how to add a marketing opt-out.

Why it matters

Respecting opt-outs keeps you compliant and protects your WhatsApp number's quality rating.
