As far as I know, this isn’t possible via the Slack integration. If Amplitude allowed us to build custom monitors that sent alerts each time the value on a chart increased, you could possibly use that custom monitor to then trigger a custom webhook to Slack to send a slack message with the alert, but the functionality of custom monitors is currently too limited to achieve what you are looking to do. 

Hello @cavalheiro! Thanks for your question. Happy to help.

At this time, there isn’t a way to set up Slack notifications for every time a specific event is fired in your project. In this case, I have filed a feature request to our Product Team on your behalf.

The closest functionality we have to what you are looking for would be what @SheenaGreen recommended which is to create a custom monitor for a value that is either above or below a particular value or percentage and then use webhooks to trigger a Slack notification. Here is the link to our documentation on custom monitors. You can also read more on webhooks in the article linked here.

I hope this helps! Let us know if you have more questions.

Appreciate the help ^^

I would love to +1 this feature request. The alert option only works for daily reporting from what I saw. I would like to send a slack notification anytime one specific event is fired as close to real time as possible.
