See the conversation around important messages

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.
