Request Structure

Each tracking request sent to Mapp Intelligence follows the same structure, regardless of whether it originates from the client-side pixel or from a server-to-server integration.

The key element of the request is the parameter p, which combines several pieces of information into a single, comma-separated string.

Structure Overview

A tracking request consists of the tracking domain, the tracking ID, and the p parameter that bundles the core information.

http[s]://[track-domain]/[track-id]/wt?p=[version],[page-name],[javascript],
    [screen-resolution],[color-depth],[cookies],
    [client-time],[referrer],[screen-size],[java]

Each value inside the p parameter is separated by a comma (,).

If a value is missing, use 0 as a placeholder.

Request Example

https://track.webtrekk.net/111111111111111/wt?p=600,home,1,1024x768,32,1,1730181123123,https%3A%2F%2Fwww.google.de,1000x700,1

This example represents a standard server-to-server pageview request sent to the Mapp Intelligence tracking server.

All values are transmitted in UTF-8 encoding.

home,                        # page name (formerly content ID)
1,                           # JavaScript active (1) / inactive (0)

Note

All parameters must be transmitted using UTF-8 encoding.

Values that include special characters (such as URLs) must be URL-encoded.

Additional Parameters

Beyond the p parameter, additional information such as IP address, referrer, or user agent can be passed as header or URL parameters — for example:

X-WT-IP=212.5.8.2
X-WT-UA=Mozilla/5.0 (Windows NT 10.0; WOW64)
X-WT-RQ=https%3A%2F%2Fsub.domain.tld%2Fhome.html

See Specific Parameters for more details.
