Track Leads - AdsCrush

AdsCrushSDK.trackLead({
  name: "John Doe",
  phone: "+1234567890",
  email: "john@example.com",
  address: "221B Baker Street",
  pincode: "400001",
  city: "Mumbai",
  state: "Maharashtra"
})

The SDK automatically uses the click ID captured from the landing page URL.

name and phone are required — the tracking API rejects leads missing either. email and all other fields are optional.

Examples

With Address Details

AdsCrushSDK.trackLead({
  name: "John Doe",
  phone: "+1234567890",
  email: "john@example.com",
  address: "221B Baker Street",
  pincode: "400001",
  city: "Mumbai",
  state: "Maharashtra"
})

With Sub-Fields

AdsCrushSDK.trackLead({
  name: "John Doe",
  phone: "+1234567890",
  email: "john@example.com",
  sub1: "campaign_123",
  sub2: "variant_a"
})

With Callbacks

AdsCrushSDK.trackLead({
  name: "John Doe",
  phone: "+1234567890",
  email: "john@example.com",
  onSuccess: (response) => console.log("Lead ID:", response.leadId),
  onError: (error) => console.error(error)
})

Key Mapping

Fill lead fields automatically from URL parameters on the current page:

AdsCrushSDK.trackLead({
  name: "John Doe",
  phone: "+1234567890",
  keymapping: ["sub1:aff_sub1", "sub2:utm_campaign"]
})
// → sub1 filled from ?aff_sub1=..., sub2 from ?utm_campaign=...
// Note: name and phone are required — pass them explicitly (or map them via keymapping).

Lead fields: name, phone, email, address, pincode, city, state, sub1–sub5, payout, currency. Explicitly provided values always win over keymapped values.

Postback Method

AdsCrushSDK.trackLead({
  name: "John",
  phone: "+1234567890",
  method: "postback",
  onSuccess: (response) => console.log(response.leadId)
})

Custom Tracking Domain

By default the SDK posts to track.adscrush.com. To use a custom tracking domain, set it once in window.adscrushConfig — it is used by both trackLead() and trackConversion():

<script>
  window.adscrushConfig = {
    domain: "track.yourdomain.com"
  }
</script>
<script src="https://sdk.adscrush.com/v1/index.iife.min.js"></script>

Or pass it directly to trackLead() — this overrides the config value for this call only:

AdsCrushSDK.trackLead({
  name: "John Doe",
  phone: "+1234567890",
  domain: "track.yourdomain.com"
})

Bare hostnames are normalized to https://; full URLs (http:// or https://) are used as-is (trailing slashes are stripped).

Deduplication

The SDK prevents duplicate leads for the same click ID. Second calls are skipped automatically. See also: Track Clicks · Track Conversions · API Reference
