Pause Sandbox
Tool to pause a running E2B sandbox preserving its filesystem and memory state. Use when you need to temporarily suspend a sandbox while maintaining its state for later resumption. Takes approximately 4 seconds per 1 GiB of RAM to pause. Paused sandboxes can be stored for up to 30 days.
Why this helps
A sandbox can keep running during a pause in work when nobody remembers to suspend it.
- Pause an identified running sandbox through a request.
- Preserve filesystem and memory state for later resumption.
- Receive a report showing the result.
Setup
Build it in a few focused steps.
- 1Connect E2B once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis: when a webhook request includes a sandbox ID and requests a pause, pause that running sandbox and report the result; flag missing IDs.
- 4Choose a webhook as the trigger and select where run reports go.
- 5Test with one real request for a sandbox that is safe to pause.

Message Status Updated
Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
