How this service works
Detected changelog update history for one tracked vendor.
Output
A JSON array of changelog change records for the Notion vendor, each including the change type (new_release, version_changed, date_changed, title_changed, breaking_signal), detection timestamp, and relevant metadata about what changed in Notion's changelog.
Example use cases
Track Notion breaking changes for integration
“Show me any breaking_signal changes detected in Notion's changelog since March 1, 2025 — I need to know if anything might break our Notion integration.”
Daily digest of Notion version updates
“Get me the latest Notion changelog updates from the past 24 hours, up to 20 results, so I can see if there were any new version releases today.”
Audit Notion changelog history for reporting
“Fetch up to 100 changelog change records for Notion going back to the start of the year — I want a full picture of all their updates for a vendor change report.”
Technical details
Endpoint
GEThttps://changelog-state-api.replit.app/api/monitors/notion/changesWhen to prefer
Use this endpoint when you need the raw detected change history for Notion's changelog — including all change event types and timestamps — rather than structured release summaries. Prefer this over the releases sibling endpoint when you need fine-grained event filtering by type (e.g. breaking_signal only) or time window, or when auditing exactly when and how Notion's changelog was updated.
Side effects
- Invalid or unrecognized vendor slug returns 404 or empty result
- Malformed since timestamp (not ISO 8601) returns 400 validation error
- limit out of range (below 1 or above 200) returns 400
- No changes found for the given filter criteria returns empty array
- Service unavailable on Replit hosting returns 5xx
