Keep an active E2B sandbox available
Send a request when work still depends on a sandbox and let Notis refresh it to extend its lifetime.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Refresh Sandbox
Extend a sandbox's lifetime to prevent it from timing out.
Why this helps
Active work can be disrupted when a needed sandbox expires before anyone remembers to refresh it.
- Extend a sandbox TTL when a task needs more time.
- Tie refreshes to an explicit incoming request.
- Reduce interruptions caused by sandbox expiration.
Setup
Build it in a few focused steps.
- 1Connect Agenty and E2B once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to refresh the E2B sandbox identified in each incoming request and report the outcome.
- 4Choose the Notis webhook trigger and select where run reports should go.
- 5Test with one real request for an active sandbox.
Questions about this workflow
Does refresh set a custom timeout?
No. Refresh Sandbox extends the TTL. Use Set Sandbox Timeout when you need to specify a timeout.
What should the request include?
It should identify the E2B sandbox that needs a TTL refresh.
