Check a travel limit from a direct message
Quickly assess whether a place fits a travel boundary mentioned in a private conversation.
Trigger
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Action
Get Isochrone
Tool to compute isochrone polygons for a given point. Use when you need to determine areas reachable within time or distance constraints.
Why this helps
A simple travel feasibility question can otherwise turn into manual map searching.
- Respond to a travel-boundary question with a calculated reachable area.
- Use the location and limit already shared in the DM.
- Reduce unstructured map checks while coordinating.
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 tell Notis the desired outcome.
- 3Use one plain-language instruction to calculate an isochrone for DMs containing a location and time or distance limit.
- 4Pick the Slack direct message trigger and a channel for run reports.
- 5Test with a real DM that includes a starting location and a limit.
Questions about this workflow
Can a message ask about time or distance?
Yes. The isochrone action computes reach within a time or distance constraint; specify which one in the DM.
What if the DM leaves out the limit?
State a suitable default in the automation prompt or ask for complete location and limit details in the message.

Supported Triggers and Actions
Notis builds workflows that link Slack to Graphhopper. A trigger fires from one place; an action lands in another.
Slack triggers
Graphhopper actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Capacity Clustering
Tool to solve capacity clustering problem. Use when assigning a set of customers to clusters to minimize total distance synchronously.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
GraphHopper Geocoding
Tool to perform forward or reverse geocoding. Use when converting between textual addresses and latitude/longitude coordinates.
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Get Isochrone
Tool to compute isochrone polygons for a given point. Use when you need to determine areas reachable within time or distance constraints.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Get Custom Profiles
Tool to retrieve a list of all user-defined routing profiles. Use when you need to list custom profiles.
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
POST Route
Tool to calculate complex routes via POST /route. Use when you need advanced route planning with custom parameters.
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Upload GPX File
Tool to upload a GPX file to a public file hosting endpoint. Returns a public URL which can be used where a 's3key' is required.
Reaction Added Trigger
DEPRECATED: use `SLACK_MESSAGE_REACTION_ADDED` instead. Triggered when a reaction is added to a message in Slack.
GraphHopper VRP POST
Tool to initiate VRP optimization. Use when you need to solve vehicle routing problems synchronously.
