Webhook_Config not sending any message

[suvendunayak]

We have created a custom webhook url. This url supposed to send message in slack (Not using slack web hook, rather custom webhook). I see from the alertmanager log that, the message has been sent successfully but I do not see the delivery of message in slack.

Config

• name: webhookD
  webhook_configs:
  • send_resolved: true
    url: https://webhookurl
    http_config:
    proxy_url: "http://proxyhost:port"

Hi! Please use https://groups.google.com/g/prometheus-users for help. GitHub issues are for feature requests and bug reports. If you want to use webhook_configs with Slack, you need to translate the JSON into something that is compatible with chat.postMessage. I would recommend using slack_configs instead.
