### 🛠️ Steps to finalize the connection:

1. **Get Your Business ID and Access Token**\
   You’ll find your Business ID in Meta Business Manager and create a long-lasting Access Token from the Developer Dashboard (you created them previously, following 1a guide).
   * 🔗 [Find your Business ID](https://business.facebook.com/settings/info)
   * 🔗 [Generate a System User Access Token](https://developers.facebook.com/blog/post/2022/12/05/auth-tokens/)<br>
2. **Paste your credentials** (created from the first step of this guide) into the CRM settings:
   * 📱 Business ID
   * 🔑 Access Token
   * 🆔 Meta App ID
   * 🛡️ App Secret
   * 🔐 Webhook Token (you defined this during Meta's App creation)<br>
3. **Click “Save Settings”** to store the values safely in Perfex CRM.<br>
4. **Click “Connect”**\
   This will verify your credentials and automatically fetch your WhatsApp Business Account ID, phone numbers, and current webhook status.
   * ✅ Confirms your access token is valid
   * 📦 Loads your WABA and linked phone numbers<br>
5. **Register Webhooks (Optional)**\
   If you've entered your App ID and App Secret, click “Register Webhook” to start receiving real-time WhatsApp messages in your CRM.

   * 🔔 Enables incoming message notifications
   * 📥 Delivers read receipts, status updates, and more
   * 🔗 [Webhook Setup Guide](https://developers.facebook.com/docs/graph-api/webhooks/getting-started#setup)
   * 🔗 [WhatsApp Webhook Reference](https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks/)<br>

Notes:

* If your Meta App ID and App Secret are provided, the webhook will be registered automatically via Meta’s API. If not, you can register it manually in the Meta Developer Console.
* Your Access Token must come from a **System User** with the correct permissions: `whatsapp_business_management` and `webhooks`.\ <br>

***

🟢 What the Buttons Do

* **Save Settings** – Stores your credentials in Perfex CRM securely.
* **Connect** – Validates your access token and fetches WABA and phone info.
* **Disconnect** – Deletes all saved Meta credentials and disables the sync.<br>

#### ✅ Tips for a Smooth Setup

* Use a **long-lived token** (valid for 60 days or more).
* Make sure your **Webhook URL** and **Webhook Token** match exactly in Meta Developer settings.
* Click **Connect** after saving to verify everything is working.
* **Keep your App Secret and Access Token safe**. Never share them or expose them to users.
