Avoid repeating booking updates in Slack
Check what the team has already discussed before adding another Appointo booking update.
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
Repeated booking messages add noise and make it harder for a busy team to see what still needs attention.
- Review recent accessible conversation history before posting.
- Reduce repetitive booking updates.
- Share only context that adds value to the discussion.
Setup
Build it in a few focused steps.
- 1Connect Appointo and Slack once in the Notis portal.
- 2Create an automation in Automations, or tell Notis in plain language from any channel.
- 3Ask Notis to retrieve relevant recent conversation history, check the booking details, and post an update only if it adds information not already present.
- 4Choose the webhook trigger and a channel for run reports.
- 5Test with one real booking and a channel with existing conversation history.
Questions about this workflow
