Other Alert Channel


I am a beginner with InfluxDB, telegraf, chronograf and Grafana.

Telegraf + influxDB + chronograf with Kapacitor work well
Telegraf+influxDB + Grafana work well
A can send Email alert with grafana but I do not find myself in all the alerts channel solutions

>>Is it possible to send an alert on a channel that is a simple TCP port via a json or anything else ?
Is there a channel that allows simple TCP in the list : https://grafana.com/docs/alerting/notifications/ (I don’t see that) ?
or can we create a custom channel ?

it is to send alerts on a third-party manager.

Thanks in advance
