Meta Cloud API

Callduck is ready to connect to the Meta Cloud API once credentials are provided. This page is the quick reference for the values themselves; for the full account walkthrough see Meta Cloud API onboarding.

What you need

• WhatsApp Business Account (WABA) ID — used to sync templates
• Phone Number ID — used to send messages (not the phone number itself)
• Permanent access token — from a Meta System User
• Verify token — a secret you choose for the webhook handshake
• App secret (optional) — enables webhook signature verification

See Phone Number ID to tell the IDs apart.

Where to add them

Enter everything under Channels → WhatsApp. Callduck stores credentials securely server-side and never sends them to the browser. Once saved, switch the channel's provider to Cloud API.

How a send works

1. You send a session reply or an approved template from Callduck.
2. Callduck calls Meta's Graph API using your Phone Number ID and access token.
3. Meta returns a message ID; delivery and read receipts arrive back via your webhook.

> Reminder: business-initiated messages outside the 24-hour customer service window must use a Meta-approved template. See Message template approval.
