Is it possible to support Webhook?
To make it easier for https://api.telegram.org to receive notification messages
Thank you very much

You can customize actions with /data/actions.d/sendmail-common.local.
The default is at /etc/fail2ban/sendmail-common.conf.

All you need is to call your webhook in python.

Alternatively, set up Apprise-API and Mailrise to use any notification system you want. You send notification emails to Mailrise triggering calls to Apprise which can call most notification systems.
