I'm currently trying to setup Prometheus and Alertmanager, the issue I have come to and haven't found solution yet, is that I want alert to be send to our custom application with oauth2 authorization.
Is there any way how to build/configure own reciever ?
Let's assume that alerts have to be sent to url https://reciever.com/pm-alert/
In this case you will need to use the webhook receiver, and implement a daemon that can take in the webhook notifications and convert them to a format that your custom application can handle.
