Resolve crypto date questions from Notion comments
When someone flags an event question in a Notion comment, ask Notis to check CoinMarketCal and return relevant dates in its report.
Trigger
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Action
List Cryptocurrency Events
Tool to retrieve list of cryptocurrency events. Use when you need to fetch upcoming or past crypto events filtered by date range, coins, categories, or other criteria. Note: Cannot retrieve events before 25/11/2017. The can_occur_before field is important as some events may happen before their stated date.
Why this helps
Questions buried in project comments can go unanswered when nobody remembers to open a separate event calendar.
- Turns a discussion question into a defined research step.
- Keeps event context connected to the page conversation.
- Reduces the chance that a date question gets dropped.
Setup
Build it in a few focused steps.
- 1Connect Notion and CoinMarketCal to Notis once; ensure the Notion connection can read comments.
- 2Create an automation in the portal or ask Notis to create it conversationally.
- 3In one instruction, ask Notis to recognize comments that ask about a crypto event or date, retrieve matching CoinMarketCal events, and report the findings.
- 4Choose the Notion Comment Created trigger and a channel for run reports.
- 5Test with one real comment containing a clear coin and event question.
Questions about this workflow
Does this need a specific page filter?
No. The comment trigger can run workspace-wide; use a page filter if you want to limit where comments are considered.
What if the comment does not name a coin?
Ask Notis to use the surrounding page context when clear, and say when it cannot identify a coin confidently.

Supported Triggers and Actions
Notis builds workflows that link Notion to Coinmarketcal. A trigger fires from one place; an action lands in another.
Notion triggers
Coinmarketcal actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
List Coins
Tool to retrieve list of all available coins/cryptocurrencies in CoinMarketCal database. Use when you need to fetch coin information including IDs, names, symbols, and event counts.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
List Event Categories
Tool to list all event categories. Use when you need to fetch available event categories.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
List Cryptocurrency Events
Tool to retrieve list of cryptocurrency events. Use when you need to fetch upcoming or past crypto events filtered by date range, coins, categories, or other criteria. Note: Cannot retrieve events before 25/11/2017. The can_occur_before field is important as some events may happen before their stated date.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
