Ways Notis can move work from Slack to Heyzine
Turn approved proposals into shareable flipbooks
When a team shares an approved proposal PDF in Slack, create a Heyzine flipbook link for easy client sharing.
Convert finalized launch decks immediately
Use a Slack post marking a launch deck final to create a Heyzine flipbook synchronously and return its links.
Queue large report conversions
When Slack shares a large report URL for publication, start an asynchronous Heyzine conversion and report its progress.
Refresh event guide sharing details
When Slack announces an updated event guide, update its Heyzine social title, description, or thumbnail details.
Password-protect a confidential board packet
When Slack marks a board packet as confidential, update the identified flipbook's password protection settings.
Retrieve an approved campaign embed
Use a designated Slack reaction on a campaign message to retrieve the flipbook embed code for the identified Heyzine publication.
Check a flipbook's social preview
When a Slack message asks for a share-preview check, retrieve the named flipbook's current social metadata.
Retrieve press kit embed details
When Slack shares a Heyzine press kit URL for embedding, retrieve its oEmbed data and HTML.
Replace investor update access list
When Slack clearly authorizes an access change, replace the named flipbook's Heyzine user access list in bulk.

Four ways to start an automation.
A trigger is the event that kicks a workflow off. Notis supports four kinds: an event in a connected app, an inbound webhook, a recurring schedule, and soon, your own database.
Integration triggers
Fire when something happens inside a connected app. New Notion page, Stripe charge, Linear issue: any of 1,000+ apps can start a workflow.
Webhook triggers
A unique URL per workflow. Anything that can send an HTTP POST can start an automation, including no-code tools that speak webhooks.
Recurring triggers
Cron-style schedules run a workflow on the clock. Daily standups, hourly syncs, business-hours-only digests: the workhorse of Notis.
Database triggers
Watch a row, query, or threshold in your own database and fire the moment the data changes. Row inserted, value crosses a limit, query starts matching.
Classic automation breaks. AI adapts.
Same triggers and actions, smarter middle. AI handles the fuzziness that breaks traditional Zapier-style workflows the moment a field gets renamed.
Describe it. Notis builds it.
Skip the visual builder. Tell Notis what you want, in plain English. It writes the workflow, you review and deploy.
You · in the Notis Builder
NEW“When a row gets added to the Q4 OKRs Notion database and the status is Blocked, send a Telegram message to the owner with a summary of what's blocking, and ping me if there's no reply within 24 hours.”
