Attribution and Affiliate Partners
Attribution platforms tell you which marketing touchpoint earned a sale. Affiliate networks pay partners for the sales they send you. Both need the same thing from your StoreFront: a reliable signal when an order completes.
You configure all of them in one place. Go to Main Menu → StoreFronts, choose your StoreFront host, then open Privacy & Tracking → Other. Each partner has its own section on that tab. Paste the credentials the partner gave you, then select Save.
Most of these integrations are server-to-server, which means UltraCart calls the partner's API after payment succeeds rather than relying on a browser pixel. Server-to-server tracking keeps reporting accurate when a shopper blocks scripts or closes the tab early.
Every server-to-server call is recorded. When a partner's numbers disagree with yours, open the Integration Log Health Report and look at the actual request and response for the order in question.

Everflow
Everflow is a partner marketing platform. The integration tracks inbound clicks and reports conversions back after payment.
- Go to Privacy & Tracking → Other → Everflow.
- Enter your Everflow domain and any parameter overrides you need.
- Select Save.

Your StoreFront watches inbound traffic for Everflow's parameters, typically
_ef_transaction_id, and stores the associated information against the session. Once payment
processes, UltraCart makes a server-to-server call to Everflow with the order details.
Attributing an upsell to Everflow
Each upsell can carry its own Everflow advertiser event ID, set in the upsell's advanced settings. When a customer takes that upsell, UltraCart records the advertiser event ID as an item property on the order and includes it in the transmission to Everflow.

Hyros
Hyros is a tracking and attribution tool for digital businesses.
- Get your API key from Hyros.
- Go to Privacy & Tracking → Other → Hyros.
- Paste the API key into the configuration field, then select Save.
Hyros publishes its own API documentation if you need to understand what the platform does with the data it receives.
Northbeam
Northbeam is an attribution platform built on first-party data.
- Go to Privacy & Tracking → Other → Northbeam.
- Enter your Data Client Id and API Key.
- Select Save.

The Northbeam integration uses the server-to-server Orders API for both initial orders and rebill orders, alongside a tracking pixel injected into the checkout. Rebills are included, so subscription revenue is attributed rather than counted only at the first purchase.
ReferralCandy
ReferralCandy runs referral and affiliate programs, tracking sales through referral links and coupon codes.
Before you start, collect two values from your ReferralCandy account:
- Access Id
- Secret Key
Then go to Privacy & Tracking → Other → ReferralCandy, enter both values, and select Save.

UltraCart then sends server-to-server conversion information to ReferralCandy. Every call to the ReferralCandy Conversion API appears in the Integration Log Health Report.
Share-A-Sale
Share-A-Sale is an affiliate marketing network.
- Go to Privacy & Tracking → Other.
- Scroll to Share-A-Sale Merchant Id.
- Enter your merchant ID, then select Save at the bottom of the page.

Configuring Share-A-Sale here rather than pasting a snippet into your receipt footer means a theme update cannot overwrite it.
If you are not using StoreFronts, configure Share-A-Sale through the legacy checkout instructions instead.
RTB House
RTB House receives order information through a webhook rather than a pixel. Provide a webhook URL in Privacy & Tracking → Other, in the RTB House section. UltraCart calls it once per order, after payment succeeds.

The webhook receives a JSON payload in this shape:
{
"date": "2024-09-08T14:30:15.123Z",
"order_id": "DEMO-12345",
"order_value": 149.99,
"device": "Desktop",
"browser": "Chrome 118.0.5993.70",
"host": "shop.example.com",
"custom_field_4": "some tracking information here",
"items": [
{
"item_id": "PROD-001",
"description": "Wireless Bluetooth Headphones",
"quantity": 1
},
{
"item_id": "PROD-002",
"description": "USB-C Charging Cable",
"quantity": 2
}
]
}
