Review tomorrow's appointment travel times
A short daily planning pass can surface travel gaps before your calendar day begins.
Trigger
Recurring schedule
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Action
Calculate Matrix
Tool to calculate distance, time, or weight matrices via POST. Use when you have multiple origins/destinations or a symmetric point set and need a single batch request.
Why this helps
Checking several appointment journeys one by one adds friction to the end of an already full day.
- Compare several appointment legs in one batch.
- Create a consistent daily travel review.
- Spot demanding travel sequences earlier.
Setup
Build it in a few focused steps.
- 1Connect Slack and GraphHopper to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to set it up conversationally.
- 3In one instruction, ask Notis to read the designated Slack appointment plan and calculate a time matrix for tomorrow's locations.
- 4Pick a daily Notis schedule and the channel for run reports.
- 5Test with a real set of upcoming appointment locations.
Questions about this workflow
Does GraphHopper read my calendar?
This workflow uses Slack as its source. Put or reference the appointment locations in the designated Slack source.
Why use a matrix?
A matrix batches travel-time calculations across multiple origins and destinations.
