Check existing lifecycle webhooks as a project starts
Before adding another notification endpoint, check the webhook registrations already in place for the team's E2B sandboxes.
Trigger
Project Created
Fires when a new Linear project is created. Covers projects in both public and private teams — polls with the connected user's token, so visibility matches what the connected user can see in Linear.
Action
List All Webhooks
Tool to retrieve all registered webhooks for your team. Use when you need to view all webhook configurations, audit webhook settings, or manage multiple webhooks.
Why this helps
Project setup can spawn duplicate notification work when existing webhook configuration is hard to find.
- Review registered webhooks during project setup.
- Reduce duplicate endpoint work and configuration confusion.
- Make lifecycle notification readiness easier to discuss with the team.
Setup
Build it in a few focused steps.
- 1Connect Linear and E2B to Notis once in the portal.
- 2Create an automation or ask Notis to list E2B webhooks for projects that need sandbox lifecycle notifications.
- 3Describe in one instruction which new projects require a webhook inventory.
- 4Select the Linear Project Created trigger and choose where run reports should appear.
- 5Test with a real project that will use E2B sandbox lifecycle events.
