# Buy Links

> Add purchase links to enable direct product sales from your pages

Buy links let customers purchase products directly from your page.

## Add a Product

### Step 1: Create Product

1. Go to "Products" → "Add Product"
2. Fill out all necessary information and define a product code
3. Include cost of goods if you want reporting

### Step 2: Embedding the Buy Link

1. Create a link tag and insert `[BUY=product_code]` or `[UPSELL=product_code]`
2. You can pass more data, e.g., `[BUY=product_code extra=abcd]`

### Step 3: Merchant Information

1. If you have a different code on Buygoods, Clickbank, or Digistore24, go to the "Merchant Information" tab
2. Associate the correct product ID from that platform

## Buy Link Formats

### Basic Buy Link

```
[BUY=your_product_code]
```

### Upsell Link

```
[UPSELL=your_product_code]
```

### Advanced Parameters

```
[BUY=product_code extra=campaign_data]
```

## Parameter Options

### Standard Parameters

* **extra**: Additional tracking data
* **quantity**: Pre-set purchase quantity
* **discount**: Apply discount codes

### Platform-Specific Affiliate Parameters

Affiliate parameters are typically passed via URL query strings to the landing page, not in buy links. The system automatically captures and tracks them:

* **ClickBank**: `hop` or `affiliate` (affiliate ID), `tid` (tracking ID/sub-affiliate)
* **Buygoods**: `aff_id` (affiliate ID), `subid` (sub-affiliate tracking)
* **Digistore24**: `aff` (affiliate ID)

<Note>
  **CBFID** (ClickBank Pitch Flow ID) is configured at the funnel level and automatically included in purchase links. You don't need to add it manually to buy links.
</Note>
