React to Browserbase run checkpoints in Slack
When a Browserbase run reaches a checkpoint worth noticing, send a webhook to Notis and let it add the agreed reaction to 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
Useful browser run updates can get buried while you are focused elsewhere, leaving teammates unsure whether anyone has seen them.
- Acknowledge a checkpoint without leaving your current task.
- Keep a lightweight signal attached to the relevant Slack message.
- Use a webhook to start the workflow when the browser run reports an update.
Setup
Build it in a few focused steps.
- 1Connect Browserbase MCP and Slack once in Notis.
- 2Create an automation by telling Notis the outcome you want, or use Automations, New Automation in the portal.
- 3In one instruction, say which reported checkpoint should receive a reaction and how Notis should identify the Slack message.
- 4Pick a webhook trigger and choose where run reports should go.
- 5Test with one real Browserbase checkpoint and confirm the intended Slack message receives the reaction.
Questions about this workflow
Does Browserbase MCP provide a trigger event for this workflow?
No Browserbase trigger events are listed here. A Notis webhook starts the workflow when an HTTP request arrives.
Can the workflow react to a Slack message if the webhook does not identify it?
Notis needs enough information to identify the intended existing Slack message. Include that reference in the webhook payload or instruction; do not assume Notis can infer unavailable history.
