Loza CRM·Updated: October 2, 2026

Quick answer

Pick a tracker, fill in the domain or API key, paste your affiliate network's macros into the parameters — get a ready postback URL. Macros are inserted raw, without encoding.

Parameters
Postback URL
https://api.connect.lozacrm.pro/postback/

Paste your affiliate network macros into the parameter values — they are not URL-encoded.

How to use

  1. Choose your tracker from the list (or Custom URL for anything else)
  2. Fill the placeholders — tracker domain or API key
  3. Paste your affiliate network's macros ({clickid}, {payout}, {sum}) into parameter values
  4. Copy the URL and paste it into the offer settings on the network side

Why you need it

A postback URL is a server-to-server callback: when a conversion happens, the affiliate network calls this URL and your tracker records the deposit. A single wrong parameter and the conversion never lands — your stats show clicks and leads, but no revenue. Getting the URL right is one of those boring tasks that decides whether a campaign looks profitable at all.

Every tracker has its own postback structure. Keitaro expects clickid and payout in the query, Voluum uses cid and txid, Loza CRM routes postbacks through a per-key endpoint. The builder holds templates for the common trackers — pick one, fill in your domain or API key, and paste the affiliate network's macros into the values.

The critical detail: macros are inserted raw. If your network uses {external_id} for the click id, that is exactly what goes into the URL — not %7Bexternal_id%7D. URL-encoding the braces makes the network send the literal text instead of the real value, which is the most common reason postbacks silently fail. This tool keeps {…}, {{…}} and __NAME__ macros untouched while still encoding ordinary characters like spaces.

For Loza CRM specifically, the postback endpoint is https://api.connect.lozacrm.pro/postback/{api_key} — drop your API key into the placeholder, map clickid to the network's click-id macro, payout to its payout macro, and optionally status for conversion states. Test it with the network's "test postback" button before launching; a fired test conversion should appear in the tracker within a minute.

FAQ

What is a postback URL?
A server-to-server URL the affiliate network calls when a conversion fires. The network replaces the macros with real values, and your tracker attributes the deposit to the original click.
Which macros are required?
At minimum a click-id macro and a payout macro. Without clickid the tracker cannot match the conversion to a click.
Why aren't the macros URL-encoded?
The network expands {clickid} before sending the request. Encoding the braces (%7Bclickid%7D) makes the macro invisible to the network — it would send literal text instead.
Where do I find my network's macros?
In the network's docs or offer settings — each uses its own syntax: {external_id}, {sum}, #s1#. Paste them into the parameter values verbatim.
How do I test a postback?
Most networks have a "test postback" button in offer settings. Fire it and confirm a test conversion appears in your tracker before spending real budget.
