Preview Trigger Outputs Before Building Workflows
Your team debates what data a Stack AI trigger will provide before committing to build a workflow. Stop guessing. This automation fetches the trigger output schema instantly when someone reacts with an emoji, letting the team see exactly what fields are available.
Trigger
Message Reaction Added
Triggers when a reaction is added to a message.
Action
Get Trigger Outputs
Retrieves the output schema for a trigger.
Why this helps
Engineers design workflows without knowing what data a trigger provides, leading to redesigns and wasted planning time when the output doesn't match expectations.
- Make informed decisions about workflow feasibility before building
- Reduce redesign cycles by understanding data availability upfront
- Embed trigger specs in planning conversations to keep context in Slack
Setup
Build it in a few focused steps.
- 1Connect Stack AI and Slack to Notis.
- 2Create an automation with the prompt: 'When someone reacts to a message mentioning a Stack AI trigger with a bookmark emoji, fetch the trigger output schema and reply with a formatted list of all available output fields.'
- 3Set the trigger to 'Message Reaction Added' and pick your lookup emoji (e.g., bookmark).
- 4Choose the Slack channel(s) where trigger lookups happen.
- 5Test by reacting to a message about a Stack AI trigger and verify the output schema appears.
Questions about this workflow
How does Notis know which trigger output to show?
Notis reads the message thread to infer the trigger being discussed. If the team mentions a specific trigger by name (e.g., 'on new email'), Notis fetches that trigger's schema. You can also ask explicitly in the reply.
Can I see data types and field descriptions?
Yes. The output schema includes field names, data types (string, integer, boolean, etc.), and descriptions of what each field represents.
What if the trigger output has many fields?
Notis can format the output as a threaded summary or collapsible list, keeping the main message clean while giving access to full details.
