I’ve setup a notification channel using Slack and while it is working well, I’d like to use the option to include the image.
My grafana server is not available from the internet, so I’ve added a Slack bot token so it can use the upload API and include the image, however, this isn’t working.
I’ve setup this bot (https://slack.com/apps/A0F7YS25R-bots) and put the token into the Grafana config.
When I test the alert, Grafana shows an error, however, the alert still gets sent, although without an image.
Has anybody successfully got Slack alerts working from an internal server with image uploads?
