Turn External Form Submissions Into Slack Channels
User submits a form. Webhook fires. Slack channel created instantly. Your team has a space to discuss the request before they know it's coming.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Create channel
Initiates a public or private channel-based conversation
Why this helps
External submissions (support requests, feature proposals, intake forms) arrive but don't automatically create team spaces—coordination happens via email or DMs instead of organized channels.
- Automatically creates team spaces for incoming requests without manual setup
- Routes different types of submissions (support, features, projects) to separate channels
- Reduces time from submission to first response by having a channel ready
- Keeps external communication organized and searchable
Setup
Build it in a few focused steps.
- 1Connect Slack to Notis.
- 2Create automation: 'Webhook channels from form submissions.'
- 3Tell Notis: 'When I send a webhook with form data, create a Slack channel based on the submission details.'
- 4Select 'Webhook' as the trigger and get your unique webhook URL.
- 5Configure your external form or system to send webhooks to that URL (e.g., Zapier, n8n, custom script).
Questions about this workflow
What information should the webhook payload contain?
Mention what's available: 'the form includes name, email, and description,' and Notis will use those to create the channel name and initial details.
Can I route different submission types to different channels?
Yes. In your prompt, describe the routing: 'if type is support, create a channel in #support-hub; if it's a feature request, create in #features.'
Can I auto-invite the form submitter or a team to the channel?
Yes. Mention this in your prompt: 'invite the submitter's email as a guest' or 'add the support team to every ticket channel.'
