WhatsApp Business API
You need: a Meta for Developers account, a number not already active on WhatsApp, a published privacy policy. Time: 30-45 minutes.
The card offers Easy Setup (the Meta wizard). Clicking the body of the card instead opens Connect WhatsApp Business API, with manual entry — that is the road to take if the wizard fails or if you want full control.
The fields
| Field | Where to find it |
|---|---|
| Account Name | your choice, it only helps you recognise the connection |
| Phone Number ID | Meta for Developers → WhatsApp → Getting Started |
| Business Account ID | same screen, or business.facebook.com/settings |
| Access Token | permanent token generated on Meta |
| App ID | at the top of the app panel |
| App Secret | Meta → App settings → Basic, press Show |
Next to Access Token there is Test: use it before saving.
Webhook
Talkzen generates two values that have to be copied over to Meta:
- Webhook URL —
https://app.talkzen.io/api/webhooks/whatsapp… - Webhook Verify Token — a hexadecimal string, different for every connection
They go into Meta under WhatsApp → Configuration → Webhook, after which the message field subscriptions have to be switched on. This is the step that gets forgotten most often, and it is the first cause of "nothing is coming in".
At the bottom of the dialog there is Test Webhook Configuration: run it before closing.
The permanent token
The one Meta shows you at the start expires in 24 hours. For the permanent one: open the WhatsApp Manager from the summary page, from the three dots choose to manage the account settings, assign the application as a resource to the system user with full control, then generate a new token with the permissions for business management, catalogue management, WhatsApp business messaging and WhatsApp business management. Copy it straight away.
