Mark the right Slack thread when Apify data is ready
Give a research handoff a clear visual cue when an Apify data-ready request reaches Notis and identifies the message to update.
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
A ready result can be missed in a busy channel when the original research discussion has moved on.
- Make ready-for-review status visible on the relevant message.
- Keep the handoff attached to the existing discussion.
- Reduce repeated checks for collection readiness.
Setup
Build it in a few focused steps.
- 1Connect Apify and Slack once in the Notis portal.
- 2Create an automation and describe when to add a review reaction.
- 3Choose a webhook trigger that receives the ready status and target message details.
- 4Choose where Notis should send run reports.
- 5Test with one real message and data-ready request.
Questions about this workflow
Will this find the correct Slack message automatically?
The webhook request or prompt context must identify the relevant channel and message. Notis cannot infer a missing message timestamp or target.
Does adding a reaction post a new Slack message?
No. This action adds a specified reaction to an existing message.
