# SAC 360º Automation – 24h Follow-up to avoid losing the WhatsApp window

In WhatsApp service (Meta's official API), there is a **24-hour window**.\
This means you can only send free-form messages while the customer interacted in the last 24 hours. After that period, it is only possible to send **template messages** approved.

To prevent the conversation from “cooling off” or the window from closing, you can create a **follow-up automation before completing 24 hours**.

### ⚙️ How to set up the 24h Follow in SAC 360º

#### 1️⃣ Access SAC 360º

You can access it in two ways:

**Menu >> General >> SAC 360º**\
or\
Type **SAC** in the **Find services**.

***

#### 2️⃣ Go to SAC Automations

Inside the module:

Click on **Automations** (or Automation Flow, if enabled for SAC).

***

#### 3️⃣ Configure the Trigger

Select the trigger:

**The time of day is**

Set a strategic time (e.g.: 09:00, 14:00 or 17:00).\
The system will perform a daily check of the services that match the rule.

***

#### 4️⃣ Configure the Condition

Add the condition:

**The date of the Lead's last message was more than 12 hours ago**\
(or the time you want before reaching 24h)

This ensures that:

* The customer is inactive
* We are still within the WhatsApp 24-hour window (Meta's official API)

***

#### 5️⃣ Configure the Action

Select:

**Send message in Service**

Example:

> Hello, {name}.\
> Can we continue with your service?\
> Give me an *OK* please!

The goal is to get the customer to write again, automatically renewing the 24-hour window.

***

### 📌 Important

* Configure so that if the customer responds, they exit the automation
* Avoid multiple sends in the same service
* Test before activating

This way you keep services active and reduce the need to send a template.
