Conversion tracking

A conversion is recorded when a transaction_id from a click is matched to a postback or pixel fire from the advertiser. Integr8 supports three methods: server-to-server postback, image pixel, and clickless postback. This page explains how matching works and helps you pick the right method.

Why it matters

Section titled “Why it matters”

Accurate conversion tracking is the foundation of every payout, every fraud signal, and every report. A misconfigured method silently loses revenue and erodes trust with publishers.

How conversion matching works

Section titled “How conversion matching works”
  1. A user clicks your tracking link. Integr8 generates a unique transaction_id.
  2. The transaction_id is passed to the advertiser’s destination URL, for example ?clickid={transaction_id}.
  3. When the user converts, the advertiser fires a postback to Integr8 with the same transaction_id.
  4. Integr8 matches the postback to the original click and records the conversion.

When to use which method

Section titled “When to use which method”
Method Use when Trade-off
S2S postback The advertiser’s system can fire a server-side request on conversion. Most reliable. Recommended default.
Image pixel S2S is not available and the advertiser controls the thank-you page HTML. Requires a custom tracking domain. Vulnerable to ad blockers.
Clickless postback Conversions have no associated click, for example direct app installs attributed by IDFA. Loses click-to-conversion attribution. Use only when no click exists.

S2S postback (server-to-server)

Section titled “S2S postback (server-to-server)”

The advertiser’s server sends a GET request to your Integr8 postback URL when a conversion occurs. Two URL forms are available.

Global postback URL works with all offers on your account:

  1. Go to Offers > Global Tracking.
  2. Expand the Conversion Global Postback card.
  3. Select the offer and copy the Server Side postback URL.
  4. Send the URL to the advertiser to fire on each conversion.

Offer-level postback URL is tied to a single offer:

  1. Go to Offers > Offers Management and open the offer.
  2. On the General tab, expand the Conversion Tracking card.
  3. Copy the postback URL and send it to the advertiser.

The URL format:

https://your.domain.com/?secure=YOUR_TOKEN&transaction_id=REPLACE

Replace REPLACE with the placeholder your advertiser uses for the click ID they received.

Image pixel

Section titled “Image pixel”

Use a 1x1 transparent image tag on the thank-you page when S2S is not available. Requires a custom tracking domain to be configured first.

<img src="https://track.yourdomain.com/event-tx?img=1" width="1" height="1" />

Generate the exact pixel URL from the Image Pixel tab in the Conversion Tracking card or from Global Tracking.

Clickless postback

Section titled “Clickless postback”

For conversions with no associated click, use the clickless postback endpoint. Include the publisher and attribution data directly in the request:

Parameter Description
publisher Publisher ID
sub_id Sub-publisher ID
session_time Timestamp of the session
conversion_ip User IP at conversion
user_agent User agent string
revenue Revenue amount
payout Publisher payout amount
external_transaction_id Publisher’s click ID
user_email Hashed or raw user email

Common pitfalls

Section titled “Common pitfalls”
  • Forgetting to include {transaction_id} in the offer redirect URL. Without it, the advertiser has nothing to pass back.
  • Hardcoding the secure token in publisher-shared URLs. The token belongs in postback URLs only.
  • Mixing global and offer-level postbacks for the same integration. Pick one path to avoid duplicate conversions.
