Mark expense questions where the conversation lives
When an expense needs a second look, Notis can use the incoming update to find the relevant Slack message and mark it for review.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Expense questions can sit in a conversation without a visible signal that someone should review them.
- Make review requests visible in Slack
- Keep the discussion attached to its existing message
- Reduce the need to repeat expense context
Setup
Build it in a few focused steps.
- 1Connect Altoviz and Slack once in Notis.
- 2Create an automation from Automations, New Automation, or tell Notis in plain language from any channel.
- 3In one instruction, ask Notis to identify expense updates needing review, find the matching Slack message using the available context, and add a review reaction.
- 4Choose the Altoviz webhook as the trigger and select where run reports should go.
- 5Test with one real expense update and verify the reaction appears on the intended message.
Questions about this workflow
How does Notis identify the Slack message?
The incoming update or available conversation context needs to provide enough information to locate the matching message.
Does this create an expense in Slack?
No. It adds a reaction to an existing Slack message that Notis identifies.
What if there is no matching message?
The instruction should tell Notis how to handle a missing match, such as reporting it without reacting. A reaction requires an existing message.
