[Alert Rule; Integrations] Sending notifications through internal integrations spams irrelevant projects.

[bmday]

Self-Hosted Version

25.5.1

CPU Architecture

x86_64

Docker Version

20.10.20

Docker Compose Version

2.36.2

Machine Specification

• My system meets the minimum system requirements of Sentry

Installation Type

up to 25.5.1

Steps to Reproduce

1. Settings - Custom Integrations - Create New Integration - Internal Integration

2. Set Name, Webhook URL (My sentry_to_mattermost exchanger). Switch Alert Rule Action -> enabled.

3. Set read permissions (Issue & Event, Alerts).

4. Select "issue" in webhooks part.

5. Save changes.

6. Add an alert rule with the default settings, but add an action to it that sends notifications using the integration you created earlier. Select project and environment. Click Send Test Notification - it should work. It works for me.

7. Save the alert rule settings.

Expected Result

I expect that whenever new tasks arise in the my_app (id 106) project, I'll receive a notification in my Mattermost via an internal integration. But I also receive notifications from all other projects in my Sentry with other project IDs.
This works as expected with my old Legacy Webhooks. However, I can't create new Legacy Webhooks because my version 25.5.1 blocks their creation as deprecated.

Why is this happening? How can I make sentry send events to my mattermost only from my my_app project?

Actual Result

My Alert Rule:

My internal integration:

Event ID

No response

You need to check your other alerts (from https://sentry.example.com/organizations/REPLACE_ME_YOUR_ORG/issues/alerts/rules/?statsPeriod=24h endpoint). Make sure you don't have this:

@aldy505, thanks for the response!
What exactly should I pay attention to in the screenshot you provided?

My guess:
"Send a notification (for all legacy integrations)". Yes, I have such alerts that use notifications through legacy integrations, but I thought this shouldn't affect other alerts, which I thought were assigned to their own projects using current internal integrations.

If so, then I'm even more confused by this logic in Sentry.

What should the alerts look like then, if I want each of my projects to have their own, individual alerts that use disjoint integrations?

I apologize if I'm asking questions that may have obvious answers. Thank you for your reply.
