Any automation/webhook app/tool for automatic Sales notifications?

Is there any already automated solutions for marketplace APIs to get notified via email/slack about new sales/evaluations/churn/downgrade/cancellation?

We are aware of the marketplace APIs:

Just wondering if somebody implemented/opensourced anything like this, or implemented a Slack app for example for this?

What are your practices getting notified by such thing? How did you solve this?

Prerequisite:

  • Found it a bit mundane logging into marketplace every day and check these manually.
