# Click Tracking Recipes

> Copy-paste EF.click() templates for every supported landing page scenario.

These are the maintained reference templates for placing `EF.click()` on a landing page. Each recipe is a complete, copy-paste snippet — pick the one that matches your funnel, replace the `INSERT_*` placeholders, and paste it before the closing `</body>` tag.

For what each option does under the hood, see [Configuration](/sdk/configuration) (organic fallback, cross-subdomain cookies) and [Click Tracking](/sdk/click-tracking) (parameters reference).

## Choosing a recipe

Answer two questions: **where does the script run**, and **what does your funnel need**?

The EF-to-EF recipes are for pages tracked by **two Everflow accounts** (a brand network forwarding clicks to a partner network).

<Note>
  If your scenario needs a combination that isn't listed here (for example Cross-Site without Organic), reach out to your CSM — these templates are maintained as a set, and we'll help you adapt one safely.
</Note>

## Basic

A standard tracking link landing on a single page. No cross-domain redirects, no organic fallback, no chained partner attribution.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
EF.click({
    offer_id: EF.urlParameter('oid'),
    affiliate_id: EF.urlParameter('affid'),
    sub1: EF.urlParameter('sub1'),
    sub2: EF.urlParameter('sub2'),
    sub3: EF.urlParameter('sub3'),
    sub4: EF.urlParameter('sub4'),
    sub5: EF.urlParameter('sub5'),
    uid: EF.urlParameter('uid'),
    source_id: EF.urlParameter('source_id'),
    transaction_id: EF.urlParameter('_ef_transaction_id'),
});
</script>
```

**Setup:**

1. Replace `INSERT_TRACKING_DOMAIN` with your network tracking domain.
2. Paste both `<script>` blocks before the closing `</body>` tag on the landing page.
3. Test by clicking through a tracking link with `?oid=N&affid=M` URL params.

## Shopify (Custom Pixel)

For Shopify checkouts using the Custom Pixel feature. There are no outer `<script>` tags (Shopify wraps the pixel itself), `__cc` carries Shopify's coupon-code parameter, and the call chains `.then(x => {})` for pixel-sandbox compatibility.

```javascript theme={null}
EF.click({
    offer_id: EF.urlParameter('oid'),
    affiliate_id: EF.urlParameter('affid'),
    transaction_id: EF.urlParameter('_ef_transaction_id'),
    sub1: EF.urlParameter('sub1'),
    sub2: EF.urlParameter('sub2'),
    sub3: EF.urlParameter('sub3'),
    sub4: EF.urlParameter('sub4'),
    sub5: EF.urlParameter('sub5'),
    uid: EF.urlParameter('uid'),
    source_id: EF.urlParameter('source_id'),
    creative_id: EF.urlParameter('creative_id'),
    coupon_code: EF.urlParameter('__cc')
}).then(x => {});
```

**Setup:**

1. In your Shopify admin: **Customer events → Add custom pixel**.
2. Paste this snippet into the pixel body (no outer `<script>` tags — Shopify adds them).
3. Set the pixel to fire on **Page viewed**.
4. Test by clicking a tracking link with `?oid=N&affid=M&__cc=PROMO`.

## Organic

A landing page that receives both tracked traffic and direct/organic traffic. Untagged visitors get attributed to a default offer and affiliate so conversions from organic sources aren't lost. See [Organic tracking](/sdk/configuration#organic-tracking) for how the fallback works.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
EF.configure({
    organic: {
        offer_id: INSERT_ORGANIC_OFFER_ID,
        affiliate_id: INSERT_ORGANIC_AFFILIATE_ID,
    }
});
EF.click({
    offer_id: EF.urlParameter('oid'),
    affiliate_id: EF.urlParameter('affid'),
    sub1: EF.urlParameter('sub1'),
    sub2: EF.urlParameter('sub2'),
    sub3: EF.urlParameter('sub3'),
    sub4: EF.urlParameter('sub4'),
    sub5: EF.urlParameter('sub5'),
    uid: EF.urlParameter('uid'),
    source_id: EF.urlParameter('source_id'),
    transaction_id: EF.urlParameter('_ef_transaction_id'),
});
</script>
```

**Setup:**

1. Replace `INSERT_TRACKING_DOMAIN`, `INSERT_ORGANIC_OFFER_ID`, and `INSERT_ORGANIC_AFFILIATE_ID`.
2. The organic fallback fires only when no `?oid` / `?affid` params are present.
3. Visit the page directly (no URL params) to verify a click is recorded against the organic offer.

## Cross-Subdomain

When your funnel spans multiple subdomains of the same site (e.g. `www.example.com` → `checkout.example.com`), the tracking cookie must be stored at the root domain so every subdomain shares attribution. The `tld` option does exactly that. See [Cross-subdomain tracking](/sdk/configuration#cross-subdomain-tracking-tld) for details.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
EF.configure({
    tld: "INSERT_TOP_LEVEL_DOMAIN"
});
EF.click({
    offer_id: EF.urlParameter('oid'),
    affiliate_id: EF.urlParameter('affid'),
    sub1: EF.urlParameter('sub1'),
    sub2: EF.urlParameter('sub2'),
    sub3: EF.urlParameter('sub3'),
    sub4: EF.urlParameter('sub4'),
    sub5: EF.urlParameter('sub5'),
    uid: EF.urlParameter('uid'),
    source_id: EF.urlParameter('source_id'),
    transaction_id: EF.urlParameter('_ef_transaction_id'),
});
</script>
```

**Setup:**

1. Replace `INSERT_TOP_LEVEL_DOMAIN` with the apex domain (e.g. `"example.com"`, including quotes).
2. Paste before `</body>` on every page in the funnel that needs to share the tracking cookie.

<Warning>
  Always load pages on a fully qualified subdomain (`www.example.com`, not `example.com`) to avoid cookie scoping issues.
</Warning>

## Organic + Cross-Subdomain

Combines the [Organic](#organic) and [Cross-Subdomain](#cross-subdomain) recipes. Use when you have organic traffic on a multi-subdomain funnel.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
EF.configure({
    tld: "INSERT_TOP_LEVEL_DOMAIN",
    organic: {
        offer_id: INSERT_ORGANIC_OFFER_ID,
        affiliate_id: INSERT_ORGANIC_AFFILIATE_ID,
    }
});
EF.click({
    offer_id: EF.urlParameter('oid'),
    affiliate_id: EF.urlParameter('affid'),
    sub1: EF.urlParameter('sub1'),
    sub2: EF.urlParameter('sub2'),
    sub3: EF.urlParameter('sub3'),
    sub4: EF.urlParameter('sub4'),
    sub5: EF.urlParameter('sub5'),
    uid: EF.urlParameter('uid'),
    source_id: EF.urlParameter('source_id'),
    transaction_id: EF.urlParameter('_ef_transaction_id'),
});
</script>
```

**Setup:**

1. Replace all four `INSERT_*` placeholders.
2. Paste before `</body>` on every page in the funnel.

## Cross-Site

When the click and the conversion happen on different domains (e.g. landing page on `brand.com`, checkout on `cart.com`). The script appends the EF transaction ID to outbound links pointing at the cross-site domain, so attribution survives the domain change.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
var siteUrl = "INSERT_CROSS_DOMAIN_URL";
var advertiserId = INSERT_ADVERTISER_ID;
var elems = document.body.getElementsByTagName("a");
EF.click({
    offer_id: EF.urlParameter('oid'),
    affiliate_id: EF.urlParameter('affid'),
    sub1: EF.urlParameter('sub1'),
    sub2: EF.urlParameter('sub2'),
    sub3: EF.urlParameter('sub3'),
    sub4: EF.urlParameter('sub4'),
    sub5: EF.urlParameter('sub5'),
    uid: EF.urlParameter('uid'),
    source_id: EF.urlParameter('source_id'),
    transaction_id: EF.urlParameter('_ef_transaction_id'),
}).then(function(transactionId) {
    if (transactionId) {
        for (var i = 0; i < elems.length; i++) {
            if (elems[i].href.includes(siteUrl)) {
                var url = new URL(elems[i].href);
                url.searchParams.set("_ef_transaction_id", transactionId);
                elems[i].href = url.href;
            }
        }
    } else if (EF.getAdvertiserTransactionId(advertiserId)) {
        for (var i = 0; i < elems.length; i++) {
            if (elems[i].href.includes(siteUrl)) {
                var url = new URL(elems[i].href);
                url.searchParams.set("_ef_transaction_id", EF.getAdvertiserTransactionId(advertiserId));
                elems[i].href = url.href;
            }
        }
    }
});
</script>
```

**Setup:**

1. Replace `INSERT_CROSS_DOMAIN_URL` with the URL fragment that identifies cross-site links (e.g. `"checkout.example.com"`).
2. Replace `INSERT_ADVERTISER_ID` with the advertiser ID used for the fallback path ([`EF.getAdvertiserTransactionId()`](/sdk/overview#helper-methods)).
3. Paste before `</body>` on the landing page only — outbound links automatically inherit the transaction ID.

## Cross-Site + Organic + Cross-Subdomain

[Cross-Site](#cross-site) tracking with organic fallback and a shared cross-subdomain cookie. Use when your funnel spans multiple domains **and** you receive organic traffic **and** your tracked subdomains need shared attribution.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
var siteUrl = "INSERT_CROSS_DOMAIN_URL";
var advertiserId = INSERT_ADVERTISER_ID;
var elems = document.body.getElementsByTagName("a");
EF.configure({
    tld: "INSERT_TOP_LEVEL_DOMAIN",
    organic: {
        offer_id: INSERT_ORGANIC_OFFER_ID,
        affiliate_id: INSERT_ORGANIC_AFFILIATE_ID,
    }
})
EF.click({
    offer_id: EF.urlParameter('oid'),
    affiliate_id: EF.urlParameter('affid'),
    sub1: EF.urlParameter('sub1'),
    sub2: EF.urlParameter('sub2'),
    sub3: EF.urlParameter('sub3'),
    sub4: EF.urlParameter('sub4'),
    sub5: EF.urlParameter('sub5'),
    uid: EF.urlParameter('uid'),
    source_id: EF.urlParameter('source_id'),
    transaction_id: EF.urlParameter('_ef_transaction_id'),
}).then(function(transactionId) {
    if (transactionId) {
        for (var i = 0; i < elems.length; i++) {
            if (elems[i].href.includes(siteUrl)) {
                var url = new URL(elems[i].href);
                url.searchParams.set("_ef_transaction_id", transactionId);
                elems[i].href = url.href;
            }
        }
    } else if (EF.getAdvertiserTransactionId(advertiserId)) {
        for (var i = 0; i < elems.length; i++) {
            if (elems[i].href.includes(siteUrl)) {
                var url = new URL(elems[i].href);
                url.searchParams.set("_ef_transaction_id", EF.getAdvertiserTransactionId(advertiserId));
                elems[i].href = url.href;
            }
        }
    }
});
</script>
```

**Setup:**

1. Replace all six `INSERT_*` placeholders.
2. Paste before `</body>` on the landing page.

## Cross-Site + Hidden Field + Organic + Cross-Subdomain

Cross-site tracking that also writes the EF transaction ID into a hidden form field on the page. Use when the conversion is sent server-side and a form POST is the trigger.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
var siteUrl = "INSERT_CROSS_DOMAIN_URL";
var advertiserId = INSERT_ADVERTISER_ID;
var elems = document.body.getElementsByTagName("a");
var field_id = "INSERT_HIDDEN_FIELD_ID";
var field = document.getElementById(field_id);
EF.configure({
    tld: "INSERT_TOP_LEVEL_DOMAIN",
    organic: {
        offer_id: INSERT_ORGANIC_OFFER_ID,
        affiliate_id: INSERT_ORGANIC_AFFILIATE_ID,
    }
})
EF.click({
    offer_id: EF.urlParameter('oid'),
    affiliate_id: EF.urlParameter('affid'),
    sub1: EF.urlParameter('sub1'),
    sub2: EF.urlParameter('sub2'),
    sub3: EF.urlParameter('sub3'),
    sub4: EF.urlParameter('sub4'),
    sub5: EF.urlParameter('sub5'),
    uid: EF.urlParameter('uid'),
    source_id: EF.urlParameter('source_id'),
    transaction_id: EF.urlParameter('_ef_transaction_id'),
}).then(function(transactionId) {
    if (transactionId) {
        for (var i = 0; i < elems.length; i++) {
            if (elems[i].href.includes(siteUrl)) {
                var url = new URL(elems[i].href);
                url.searchParams.set("_ef_transaction_id", transactionId);
                elems[i].href = url.href;
            }
        }
        field.value = transactionId;
    } else if (EF.getAdvertiserTransactionId(advertiserId)) {
        for (var i = 0; i < elems.length; i++) {
            if (elems[i].href.includes(siteUrl)) {
                var url = new URL(elems[i].href);
                url.searchParams.set("_ef_transaction_id", EF.getAdvertiserTransactionId(advertiserId));
                elems[i].href = url.href;
            }
        }
        field.value = EF.getAdvertiserTransactionId(advertiserId);
    } else {
        field.value = "No EFTID";
    }
});
</script>
```

**Setup:**

1. Replace all seven `INSERT_*` placeholders. `INSERT_HIDDEN_FIELD_ID` is the `id` attribute of an `<input type="hidden">` in your form.
2. Add the hidden input to your form: `<input type="hidden" id="ef_tid" name="ef_tid">`
3. Paste before `</body>`. The script populates the hidden field on page load; the form POST carries it server-side.

## Cross-Site + Hidden Field + Organic + Cross-Subdomain + Async

Same as the [previous recipe](#cross-site-hidden-field-organic-cross-subdomain) but loads the SDK asynchronously so it never blocks page render. Use when the landing page has page-speed concerns or the SDK shouldn't block above-the-fold content.

```html theme={null}
<script type="text/javascript">
var script = document.createElement('script');
script.src = "https://INSERT_TRACKING_DOMAIN/scripts/main.js";
script.defer = true;
script.onload = function() {
    var siteUrl = "INSERT_CROSS_DOMAIN_URL";
    var advertiserId = INSERT_ADVERTISER_ID;
    var elems = document.body.getElementsByTagName("a");
    var field_id = "INSERT_HIDDEN_FIELD_ID";
    var field = document.getElementById(field_id);
    EF.configure({
        tld: "INSERT_TOP_LEVEL_DOMAIN",
        organic: {
            offer_id: INSERT_ORGANIC_OFFER_ID,
            affiliate_id: INSERT_ORGANIC_AFFILIATE_ID,
        }
    })
    EF.click({
        offer_id: EF.urlParameter('oid'),
        affiliate_id: EF.urlParameter('affid'),
        sub1: EF.urlParameter('sub1'),
        sub2: EF.urlParameter('sub2'),
        sub3: EF.urlParameter('sub3'),
        sub4: EF.urlParameter('sub4'),
        sub5: EF.urlParameter('sub5'),
        uid: EF.urlParameter('uid'),
        source_id: EF.urlParameter('source_id'),
        transaction_id: EF.urlParameter('_ef_transaction_id'),
    }).then(function(transactionId) {
        if (transactionId) {
            for (var i = 0; i < elems.length; i++) {
                if (elems[i].href.includes(siteUrl)) {
                    var url = new URL(elems[i].href);
                    url.searchParams.set("_ef_transaction_id", transactionId);
                    elems[i].href = url.href;
                }
            }
            field.value = transactionId;
        } else if (EF.getAdvertiserTransactionId(advertiserId)) {
            for (var i = 0; i < elems.length; i++) {
                if (elems[i].href.includes(siteUrl)) {
                    var url = new URL(elems[i].href);
                    url.searchParams.set("_ef_transaction_id", EF.getAdvertiserTransactionId(advertiserId));
                    elems[i].href = url.href;
                }
            }
            field.value = EF.getAdvertiserTransactionId(advertiserId);
        } else {
            field.value = "No EFTID";
        }
    });
}
document.body.append(script);
</script>
```

**Setup:**

1. Replace all seven `INSERT_*` placeholders.
2. Paste this single block before `</body>` — note this version is one combined `<script>`, not two.
3. The SDK loads with `defer` so it doesn't block render; tracking fires once the SDK finishes loading.

## EF to EF

When a brand network forwards clicks to a partner network on the same page (e.g. a brand running a partner program through another Everflow instance). The partner click fires first; its transaction ID becomes `sub5` on the brand click.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_BRAND_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
if (EF.urlParameter("affid2")) {
  EF.click({
    tracking_domain: "https://INSERT_PARTNER_TRACKING_DOMAIN",
    offer_id: EF.urlParameter("oid2"),
    affiliate_id: EF.urlParameter("affid2"),
    sub1: EF.urlParameter("sub1"),
    sub2: EF.urlParameter("sub2"),
    sub3: EF.urlParameter("sub3"),
    sub4: EF.urlParameter("sub4"),
    sub5: EF.urlParameter("sub5"),
  }).then(function (transaction_id) {
    EF.click({
      tracking_domain: "https://INSERT_BRAND_TRACKING_DOMAIN",
      offer_id: EF.urlParameter("oid"),
      affiliate_id: EF.urlParameter("affid"),
      sub1: EF.urlParameter("sub1"),
      sub2: EF.urlParameter("sub2"),
      sub3: EF.urlParameter("sub3"),
      sub4: EF.urlParameter("sub4"),
      sub5: transaction_id,
      uid: EF.urlParameter("uid"),
      source_id: EF.urlParameter("source_id"),
    });
  });
} else {
  EF.click({
    tracking_domain: "https://INSERT_BRAND_TRACKING_DOMAIN",
    offer_id: EF.urlParameter("oid"),
    affiliate_id: EF.urlParameter("affid"),
    sub1: EF.urlParameter("sub1"),
    sub2: EF.urlParameter("sub2"),
    sub3: EF.urlParameter("sub3"),
    sub4: EF.urlParameter("sub4"),
    sub5: EF.urlParameter("sub5"),
    uid: EF.urlParameter("uid"),
    source_id: EF.urlParameter("source_id"),
    transaction_id: EF.urlParameter("_ef_transaction_id"),
  });
}
</script>
```

**Setup:**

1. Replace `INSERT_BRAND_TRACKING_DOMAIN` and `INSERT_PARTNER_TRACKING_DOMAIN`.
2. Tracking links from the partner network must include `?affid2=` and `?oid2=` params.
3. Visitors with `affid2` get the chained pattern; visitors without it are attributed only to the brand network.

<Note>
  The chained pattern reserves `sub5` on the brand click for the partner transaction ID — it overrides any incoming `sub5` value. Plan your sub-placement usage accordingly.
</Note>

## EF to EF + Organic + Cross-Subdomain

The [EF to EF](#ef-to-ef) chain plus organic fallback and a shared cross-subdomain cookie. The else branch (no `affid2`) gets the full Organic + Cross-Subdomain configuration.

```html theme={null}
<script type="text/javascript"
    src="https://INSERT_BRAND_TRACKING_DOMAIN/scripts/main.js"></script>

<script type="text/javascript">
if (EF.urlParameter("affid2")) {
  EF.click({
    tracking_domain: "https://INSERT_PARTNER_TRACKING_DOMAIN",
    offer_id: EF.urlParameter("oid2"),
    affiliate_id: EF.urlParameter("affid2"),
    sub1: EF.urlParameter("sub1"),
    sub2: EF.urlParameter("sub2"),
    sub3: EF.urlParameter("sub3"),
    sub4: EF.urlParameter("sub4"),
    sub5: EF.urlParameter("sub5"),
  }).then(function(transaction_id) {
    EF.configure({
      tld: "INSERT_TOP_LEVEL_DOMAIN",
    })
    EF.click({
      tracking_domain: "https://INSERT_BRAND_TRACKING_DOMAIN",
      offer_id: EF.urlParameter("oid"),
      affiliate_id: EF.urlParameter("affid"),
      sub1: EF.urlParameter("sub1"),
      sub2: EF.urlParameter("sub2"),
      sub3: EF.urlParameter("sub3"),
      sub4: EF.urlParameter("sub4"),
      sub5: transaction_id,
      uid: EF.urlParameter("uid"),
      source_id: EF.urlParameter("source_id"),
    });
  });
} else {
  EF.configure({
    tld: "INSERT_TOP_LEVEL_DOMAIN",
    organic: {
      offer_id: INSERT_ORGANIC_OFFER_ID,
      affiliate_id: INSERT_ORGANIC_AFFILIATE_ID,
    }
  })
  EF.click({
    tracking_domain: "https://INSERT_BRAND_TRACKING_DOMAIN",
    offer_id: EF.urlParameter("oid"),
    affiliate_id: EF.urlParameter("affid"),
    sub1: EF.urlParameter("sub1"),
    sub2: EF.urlParameter("sub2"),
    sub3: EF.urlParameter("sub3"),
    sub4: EF.urlParameter("sub4"),
    sub5: EF.urlParameter("sub5"),
    uid: EF.urlParameter("uid"),
    source_id: EF.urlParameter("source_id"),
    transaction_id: EF.urlParameter("_ef_transaction_id"),
  });
}
</script>
```

**Setup:**

1. Replace all five `INSERT_*` placeholders.
2. Same setup as the basic [EF to EF](#ef-to-ef) chain; the else branch handles untagged and organic traffic.
