Overview
This article is for website owners who want to integrate their website with Trackier using Server-to-Server (S2S) postback tracking. It covers how to capture Trackier's click ID in your web URL and fire it back via a postback when a user converts — enabling accurate, server-level conversion attribution.
What is S2S Integration?
Server-to-Server (S2S) integration is a method of tracking conversions directly between two servers your website's server and Trackier's server without relying on browser cookies or JavaScript pixels.
When a user clicks a Trackier tracking link and lands on your website, Trackier generates a unique click ID that gets stored on your end. When the user completes a conversion action (such as a registration or purchase), your server fires a postback to Trackier containing that click ID, allowing Trackier to attribute the conversion accurately.
Example of campaign URL: https://www.yourwebsite.com?xyz={click_id}
Why Use S2S Integration?
Most reliable conversion tracking method — not affected by ad blockers, browser restrictions, or cookie loss
Real-time conversion reporting in your Trackier panel
No third-party JavaScript or pixel required on your website
Accurate attribution even across multiple redirects or sessions
Steps to set up S2S integration
Step 1: Setting Up the Web URL Correctly.
This is the first step in the process, where you must ensure that you collect the click ID that Trackier is responsible for generating and store it on your end as a user session.
Add the parameter in the URL where you want to store the click IDs generated by Trackier. Against that parameter, place the {click_id} macro
For instance:
Campaign setup with your web URL: In your web URL, add an appropriate parameter, let's say XYZ. If you want to receive click ids in this parameter, place the macro {click_id} against it, as visible in the screenshot below.
Redirection and click-id generation
Whenever the Trackier URL is hit, redirection happens, and that URL is redirected to the campaign URL that you set up. During that redirection, the {click_id} macro gets replaced with the 24-character click ID, which will be unique for each click. This click ID will be stored in your XYZ parameter.
In the screenshot URL, you can see:
The Trackier URL is getting redirected to your web URL.

Step 2: Firing Postback with the click ID
Once you get the click ID through Trackier and get a confirmation that the user completed the registration, you have to send the click ID back to Trackier through postback.
You will get a Postback from Trackier once a campaign is created
You need to fire a postback with the same click ID that you received in the web URL.
For instance: Sample postbacks
You will get a postback in the below format:
You will receive the post back in this format
You need to replace CLICK_ID with the parameter you have used in the web URL for Trackier Click ID.
In this case, we have taken the example of XYZ
So you need to make sure that when you fire the postback, the 24-character click ID you have received via web URL under the XYZ parameter will fire the same when the user completes the registration.
Postback Parameter Reference
Parameter | Description |
| The 24-character click ID generated by Trackier and stored in your web URL parameter |
| Your unique security token — provided by Trackier when the campaign is created |
Note: The same call you need to make through your server in real-time, you will get response from our end as {"success":true,"message":"QUEUED"}
Common Mistakes to Avoid
Not storing the click ID from the URL parameter when the user first lands on your website
Firing the postback from the browser (JavaScript) instead of the server, this makes it a pixel, not an S2S integration
Using a different parameter name in the postback than the one used to capture the click ID in Step 1
Delaying the postback fire it should be triggered at the exact moment the conversion occurs
Broaden your knowledge:
Conclusion
S2S integration with Trackier gives you the most reliable and accurate method for tracking conversions from your website. By capturing the click ID when users land on your page and returning it via a server postback when they convert, you ensure that every conversion is attributed correctly — with no dependency on browser cookies or third-party scripts.
