Spot Changes to Dates on Important Pages
Let a scheduled page check surface a changed date and the calendar entry that may need attention.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Find event
Finds events in a specified google calendar using text query, time ranges (event start/end, last modification), and event types; ensure `timemin` is not chronologically after `timemax` if both are provided.
Why this helps
When an event date changes on a webpage, the old calendar entry can remain unnoticed.
- Check a known page on a recurring schedule.
- Compare the page's stated date with a reference date you provide.
- Find a likely related event in Google Calendar for review.
Setup
Build it in a few focused steps.
- 1Connect Cloudflare browser rendering and Google Calendar once in the Notis portal.
- 2Create an automation named Recurring Page Date Change Check.
- 3In one instruction, provide the page URL and reference date, and tell Notis to extract the current date, compare it with that reference, and find a related calendar event when a change appears.
- 4Choose the recurring schedule trigger and select where run reports should go.
- 5Test with one real page and a matching calendar event.
Questions about this workflow
Can Notis know the page's earlier date automatically?
Only if you supply the reference date or another available source for the prior value. The page renderer does not provide missing history by itself.
Does this automatically change the calendar event?
This workflow finds the likely event for review. You can separately configure an update action if you want Notis to make changes automatically.
