Start an E2B sandbox from a Slack request
Ask in Slack for a fresh coding environment and let Notis launch an E2B sandbox for the work.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Create Sandbox
Tool to create a new E2B sandbox from a template. Use when you need to launch a fresh sandbox environment for code execution, testing, or development purposes.
Why this helps
A request for a new environment can get buried while you stop what you are doing to create one.
- Reduces the steps between asking for an environment and getting started.
- Keeps the request in the channel where the team is already coordinating.
Setup
Build it in a few focused steps.
- 1Connect Slack and E2B to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to make one in plain language.
- 3Instruct Notis to create a new E2B sandbox when someone requests a fresh coding environment in Slack.
- 4Choose the Slack channel message trigger and a channel for run reports.
- 5Test it with one real request for a fresh environment.
Questions about this workflow
Does this start a sandbox for every channel message?
Describe the intended request clearly in the automation prompt so Notis can recognize the relevant messages.
Do I need to map Slack fields to E2B fields?
No. The automation uses a plain-language instruction rather than a field-mapping screen.
