Keep source coverage honest when your tracker evolves
Reworking a tracker's columns is exactly when things quietly slip. When your Notion data source schema changes, Notis re-verifies that the news sources you rely on are still monitored, so a structural edit never leaves an unnoticed coverage gap.
Trigger
Data Source Schema Updated
Fires when a data source’s columns are added, removed, or renamed.
Action
Search News Sources
Find monitored news sources by partial name and view their URLs and languages.
Why this helps
Restructuring a tracker feels like progress, but it is also when assumptions about what is covered silently break.
- Re-verifies coverage exactly when the tracker is edited.
- Catches gaps introduced by a structure change.
- Keeps a maturing tracker trustworthy over time.
Setup
Build it in a few focused steps.
- 1Connect Notion and World News API to Notis once from the portal.
- 2In Automations, click New Automation and name it 'Schema change coverage check'.
- 3Write the plain-language prompt, for example: 'When this tracker's schema changes, re-check that its listed sources are still monitored and flag any that are not.'
- 4Choose the Data Source Schema Updated trigger and scope it to your tracker.
- 5Set the reporting channel, then rename a column to test the re-check.
Questions about this workflow
What counts as a schema change?
Adding, removing, or renaming a column in the data source fires this trigger.
Can I scope it to one tracker?
Yes. The trigger accepts a data source filter so only your chosen tracker runs the check.
Will editing rows trigger it?
No. This is a structural signal, so ordinary row edits do not fire it.
