Resolve invoice currency questions with the dated rate
A question on an invoice can prompt a historical rate lookup for its transaction date, keeping the follow-up grounded in the right period.
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
Get Historical Exchange Rates
Tool to retrieve historical exchange rate data for past dates going back to 1996. Use when you need to access exchange rates for a specific historical date with a base currency.
Why this helps
A comment about an old invoice can lead to a context switch just to find which rate applied on the relevant date.
- Look up the rate tied to the invoice date under discussion.
- Reduce back-and-forth over which day to check.
- Keep a useful rate reference with the invoice conversation.
Setup
Build it in a few focused steps.
- 1Connect Notion and CurrencyScoop to Notis once.
- 2Create an automation in the portal or tell Notis what invoice comments should prompt a lookup.
- 3Write one instruction asking for the historical rate based on the invoice date, base currency, and quote currency stated on the page.
- 4Select the Notion Comment Created trigger, scope it to the invoice page if useful, and choose a channel for run reports.
- 5Test by adding a comment to an invoice with a date and currency pair.
Questions about this workflow
Does the comment need to include all invoice details?
The invoice page or comment should make the relevant date and currency pair clear to Notis.
Can the trigger cover all invoice comments?
The comment event can be scoped to a page or left workspace-wide, subject to the integration's comment access.

Supported Triggers and Actions
Notis builds workflows that link Notion to CurrencyScoop. A trigger fires from one place; an action lands in another.
Notion triggers
CurrencyScoop actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Convert Currency
Tool to perform a single currency conversion from one currency to another for a specified amount. Use when you need to convert a specific amount between two currencies using mid-market rates.
Webhook trigger

Get Historical Exchange Rates
Tool to retrieve historical exchange rate data for past dates going back to 1996. Use when you need to access exchange rates for a specific historical date with a base currency.
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.
Get Latest Exchange Rates

New Comment
Triggers when a new comment is added to a specified Notion block or page.
Get Timeseries Exchange Rates
Tool to retrieve historical exchange rates for a given time period between start and end dates. Use when you need exchange rates for multiple dates in a date range for trend analysis or historical comparisons.
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.
