# Activation Request

To approve an eSIM activation via SDK, you need to implement this callback on your server. If the client is allowed to install an eSIM, a successful response is expected from our backend. Gigastore is sending the webhook as a POST request.

{% hint style="info" %}
Please provide your server URL to your Gigastore contact. \
Only **HTTPS** server URLs are allowed. 
{% endhint %}
