Use a Slack reaction to start a grocery list
A single agreed reaction can tell Notis that a message's grocery items are ready to collect.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Create Shopping List Page
Create a shopping list page on instacart + return shareable url. attempts prod first then falls back to dev; errors from prod bubble up if both fail.
Why this helps
A team may agree on items but still leave someone to manually copy them into a shopping list.
- Turns a lightweight reaction into a clear handoff
- Keeps list creation tied to a reviewed message
- Avoids copying grocery details by hand
Setup
Build it in a few focused steps.
- 1Connect Slack and Instacart to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to create an Instacart list from a Slack message marked with the agreed check reaction.
- 3Choose Slack Message Reaction Added as the trigger and select a channel for run reports.
- 4Test by adding the agreed reaction to a real message containing grocery items.
