Every New Channel Gets Documented: Slack to Notion
A new Slack channel gets created. Notis immediately creates a Notion page documenting the channel's purpose, who's in it, and how it should be used.
Trigger
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Action
Create Notion page
Creates a new empty page in a notion workspace.
Why this helps
New Slack channels proliferate but rarely get documented. Neurodivergent founders struggle to keep track of channel purposes and decisions about who belongs where. New team members don't know which channels to join or why they exist, leading to confusion and duplicated channels.
- Maintain a searchable directory of all Slack channels with purpose and guidelines
- Reduce confusion for new team members about which channels to join
- Create a record of why channels were created and how they should be used
Setup
Build it in a few focused steps.
- 1Connect Slack and Notion to Notis in the portal.
- 2Tell Notis: 'Whenever a new Slack channel is created, create a Notion documentation page with the channel name, description (if available), creation date, and space for guidelines and member list.'
- 3Select 'New Channel Created' as your trigger.
- 4Point Notis to your Notion channels documentation folder.
- 5Test by creating a new Slack channel and verify Notion creates a documentation page.
Questions about this workflow
Will Notis pull the channel description from Slack?
Yes. If the Slack channel has a description or topic set, Notis will include it in the Notion page. If not, it leaves space for you to add one.
Can Notis automatically list channel members?
Yes. Your automation can ask Notis to fetch the member list from Slack and add it to the Notion page, which is helpful for onboarding.
What if I want to archive a Slack channel and clean up the Notion page?
You can manually archive the Notion page, or set up a separate automation that listens for archived Slack channels and archives the Notion pages.

Supported Triggers and Actions
Notis builds workflows that link Slack to Notion. A trigger fires from one place; an action lands in another.
Slack triggers
Notion actions
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Add multiple content blocks (bulk, user-friendly)
Efficiently adds multiple standard content blocks to a notion page in a single api call with automatic markdown parsing. the 'content' field in notionrichtext blocks now automatically detects and parses markdown formatting including headers (# ## ###), bold (**text**), italic (*text*), strikethrough (~~text~~), inline code (`code`), links ([text](url)), and more. ideal for bulk content creation, ai agents, and replacing multiple individual add page content calls. supports automatic text formatting, content splitting, and up to 100 blocks per request.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Add content to Notion page
Deprecated: appends a single content block to a notion page or a parent block (must be page, toggle, to-do, bulleted/numbered list, callout, or quote); invoke repeatedly to add multiple blocks.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Append complex blocks (advanced, full control)
Appends complex blocks with full notion block structure to a parent block or page. use for advanced scenarios requiring precise control: code blocks, tables, embeds, nested children within blocks, or when working with pre-built notion block objects. requires full notion api block schema - use add multiple page content for simpler content creation.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Archive Notion Page
Archives (moves to trash) or unarchives (restores from trash) a specified notion page.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Create comment
Adds a comment to a notion page (via `parent page id`) or to an existing discussion thread (via `discussion id`); cannot create new discussion threads on specific blocks (inline comments).
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
Create Notion Database
Creates a new notion database as a subpage under a specified parent page with a defined properties schema; use this action exclusively for creating new databases.
Reaction Removed Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_REMOVED` instead. Triggered when a reaction is removed from a message.
Create Notion page
Creates a new empty page in a notion workspace.
New Bot Message Received Trigger
DEPRECATED: use `SLACK_CHANNEL_MESSAGE_RECEIVED` with `is_bot_message=true` instead. Triggered when a new bot message is posted to a Slack channel.
Delete a block
Archives a notion block, page, or database using its id, which sets its 'archived' property to true (like moving to "trash" in the ui) and allows it to be restored later.
