📍 Where to find it: Inboxes → (your WhatsApp inbox) → Settings → "Configuration" tab

After connecting, the Configuration tab of a WhatsApp inbox lets you sync your message templates, update the API key, review the webhook and verify token, or relaunch the guided sign-in.

How it works

Madyis Hub queries Meta to retrieve your approved WhatsApp templates (used for campaigns and follow-ups outside the 24-hour window). For inboxes connected manually, the webhook, the verify token and the API key are displayed and editable. For inboxes using guided sign-in, a button lets you relaunch/reconfigure the connection. An "Account status" tab also shows the number's health (sending tier, etc.).

Step by step

  1. Inboxes → Settings of your WhatsApp inbox → "Configuration" tab.
  2. Click "Sync templates" to retrieve your templates approved by Meta.
  3. For a manual connection: copy the displayed webhook/token, or paste a new API key then "Update".
  4. For a guided connection: use "Reconfigure" to relaunch the Meta window.
  5. Check the "Account status" tab to verify the health and sending tier of your number.

Good to know

  • Sync your templates before launching a WhatsApp campaign, otherwise your templates will not be offered.
  • An image header is often mandatory for certain templates: an incomplete template can fail silently.
