I tried to send alerts from Sumologic
to Slack. But when I test the connection, it always failed and return 400 http
code. I used the connection type as Webhook
When test the connection, it should pass
If you are using WebHook and testing the connection, you must use a valid payload. If you don't provide a valid payload, the connection test will not succeed.
You can use the connection type as SLACK over WebHook. Still, you are using a webhook URL.
This link shows how to integrate Sumologic with Slack. https://www.youtube.com/watch?v=qEz8dcp9SgI
