The goal is to make reports in Matomo, with link directory service customized by visitors.

Ametys would only gather, compute and send stats to Matomo through "events".

Matomo would do the reporting on his side.

Here is an example of http request to send to matomo (one for each customizable service ). Here we have 34 people who have customized them service "Mes Applications":

// GET https://your-matomo-domain/matomo.php
?idsite=1
&rec=1
&apiv=1
&e_c=engagement
&e_a=customization_count
&e_n=Mes%20Applications
&e_v=34
&cdt=2025-04-24%2000:00:00
&token_auth=your_token_here

Note that Matomo offers javascript and java SDK : https://developer.matomo.org/api-reference/tracking-java
