Quick Context: Fetch Slide and Slack History On-Demand
You jump into a meeting and need context on recent updates. Instead of switching between tabs and scrolling through history, Notis fetches the last week of presentation changes and Slack conversation in seconds via a webhook.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Fetch conversation history
Fetches a chronological list of messages and events from a specified slack conversation, accessible by the authenticated user/bot, with options for pagination and time range filtering.
Why this helps
Jumping into discussions without context wastes everyone's time—finding recent changes requires tab-switching and manual scrolling.
- Context arrives instantly without manual searching
- Perfect for joining meetings late or switching between projects
- Reduces cognitive load of context-switching
Setup
Build it in a few focused steps.
- 1Connect Google Slides and Slack.
- 2Create an automation named 'Fetch presentation context'.
- 3Enter: 'When triggered via webhook, fetch the last 7 days of updates to [presentation-name] and recent Slack messages from [channel-name].'
- 4Select 'Webhook' as the trigger type.
- 5Before a meeting, call the webhook URL and get a summary—no tab-switching needed.
