# Balance Activation

eSIMPAY sends notifications via **POST** webhook when a data balance is activated. This helps you track the moment a user starts using mobile data — especially in **FIRST\_USE** and **ON\_DEMAND** activation modes.

{% hint style="info" %}
Specify your server's URL in eSIMPAY. Only HTTPS addresses are allowed.
