Never Lose Slack Context Again: Threads to Notion Pages
A critical discussion happens in Slack. Weeks later, the channel is archived. With Notis, that conversation is already a searchable Notion page that your team can reference forever.
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 Notion page
Creates a new empty page in a notion workspace.
Why this helps
Slack conversations are ephemeral by design. Important context, lessons learned, and decision rationales vanish when channels are pruned or when you need to search back months later. Neurodivergent founders struggle especially when critical information lives nowhere but in distributed channel archives.
- Build a permanent, searchable knowledge base from ephemeral Slack chatter
- Recover context months later without wading through archived Slack
- Keep critical team knowledge in one discoverable location
Setup
Build it in a few focused steps.
- 1Connect Slack and Notion to Notis in the portal.
- 2Tell Notis: 'When a message with a certain keyword or emoji reaction is posted in a Slack channel, create a new Notion page with that message and any replies'.
- 3Choose 'Channel Message Received' as your trigger, then specify the channel and keyword (or set up 'Message Reaction Added' with a specific emoji like 'bookmark').
- 4Point Notis to the Notion folder where it should create the archive pages.
- 5Test by posting a sample message and verify the Notion page appears with the full thread.
Questions about this workflow
Will Notis capture the entire thread or just the first message?
Your automation prompt controls that. Tell Notis to include replies, and it will capture the full thread context. You can also ask it to format the conversation for readability.
Can I automatically tag or organize Notion pages by topic?
Yes. Your Notis prompt can ask it to analyze the Slack message and add relevant tags, categories, or properties to the Notion page automatically.
What if someone posts off-topic messages I don't want archived?
Set specific triggers, like 'only messages from a certain channel' or 'only messages with a specific emoji reaction.' Notis will ignore the rest.

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.
