Archive important Slack channel context in Ably

Keep a durable real time trail of the Slack updates your team depends on.

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

Get Channel History

This tool retrieves the message history for a specified ably channel. it uses the get /channels/{channelid}/messages endpoint to return a paginated list of messages in chronological order, subject to parameters such as 'channelid', 'limit', 'direction', 'start', and 'end'. the tool is useful for auditing, recovering missed messages, analyzing channel activity, and debugging message flows. authentication is required via basic or token authentication.

Why this helps

Critical context disappears into fast moving channels before anyone can review it.

  • Creates a retrievable event trail
  • Supports later incident review
  • Reduces repeated questions

Setup

Build it in a few focused steps.

  • 1Connect Slackbot and Ably once in Notis.
  • 2Create an automation for archiving selected channel messages.
  • 3Tell Notis to publish qualifying messages to an Ably channel with useful metadata for later history queries.
  • 4Pick the Slack channel message trigger and report destination.
  • 5Test with one message you want retained.

Questions about this workflow

Does the history action write the message itself?

The workflow publishes the selected message to Ably, where channel history can retrieve it later.
