Why this helps
Follow-up signals in chat are easy to miss when nobody turns them into a concrete next step.
- Turns a lightweight reaction into a clear market follow-up.
- Keeps the original message as context for the requested asset.
- Avoids manually reopening a conversation to search for a price.
Setup
Build it in a few focused steps.
- 1Connect Slack and CoinMarketCap to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to create it conversationally.
- 3Give Notis one plain-language instruction to find the asset named in the reacted-to message and retrieve its latest quote.
- 4Choose the Slack reaction-added trigger and select a channel for run reports.
- 5Test by reacting to a real message that names a cryptocurrency.
