Mark an Alpha Vantage alert with a Slack reaction
When an external system calls your Notis webhook, check the market data you named and mark the relevant Slack message.
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
Market alert context can get lost when it arrives outside the conversation where the team is coordinating.
- Use an HTTP request as the workflow starting point.
- Check requested Alpha Vantage data before acting.
- Make a matching Slack message easier to spot with a reaction.
Setup
Build it in a few focused steps.
- 1Connect Alpha Vantage and Slack once in the Notis portal.
- 2Create an automation in Automations, New Automation, and name it.
- 3In one instruction, describe the incoming alert, the Alpha Vantage data to check, and when to react to a matching Slack message.
- 4Choose a webhook as the trigger and select a channel for run reports.
- 5Test with one real example and review the Slack result.
Questions about this workflow
What starts this workflow?
An HTTP request to the Notis webhook starts it. Your external system must be configured to send that request.
Can this workflow create a Slack message if none exists?
This package uses the add reaction to message action, which requires an existing message in a channel and its timestamp.
