# Post-Delivery Followup

> Automated WhatsApp messages sent after order delivery

## What is Post-Delivery Followup?

Post-Delivery Followup is an **automated** WhatsApp message sent a configurable number of days after an order is marked as delivered. It encourages customers to share their referral link after they've had time to use and enjoy the product.

Unlike manual [Nudges](/docs/features/nudges), post-delivery followups are **fully automatic** — once configured, they run without any manual intervention.

## How It Works

```mermaid theme={null}

    A[Order Delivered] --> B[Wait X Days]
    B --> C[Send WhatsApp Message]
    C --> D[Customer Shares Referral]
```

1. A customer's order is marked as **Delivered** in Shopify.
2. Referbro schedules a follow-up message for **X days** later.
3. A background job sends the WhatsApp message at the scheduled time.
4. The message includes the customer's unique referral code and link.

## Configuration

### 1. Enable the Template

Go to **Apps → Referbro → WhatsApp Settings** and configure the **Post Delivery Followup Template**:

* **Template ID** — The approved template name from your WhatsApp provider.
* **Template Parameters** — JSON parameter mapping (see [Template Reference](/docs/features/whatsapp/overview#template-parameters)).
* **Days after delivery** — How many days to wait after delivery before sending (default: `7` days).

### 2. Ensure Delivery Status Syncs

<Important>
  Orders must be marked as **Delivered** in Shopify Admin for follow-ups to trigger. If you use a 3PL or shipping service, ensure delivery status syncs back to Shopify under **Orders → Fulfillment**.
