Get nearby channel context when a message matters, so you can respond with less backtracking.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
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
A single message may not make sense without the conversation around it, prompting extra tab switching and searching.
- Adds surrounding conversation context
- Reduces manual backtracking
- Helps responses account for prior discussion
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Slack to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to fetch context for significant messages.
- 3Describe which messages need recent channel history and what context is useful.
- 4Select the channel-message trigger and choose a channel for run reports.
- 5Test with one real message and confirm the retrieved history provides useful context.
