Tag promising candidates from Slack reactions
A single team signal can keep Ashby organized without another data entry task.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Add Candidate Tag
Add a tag to a candidate in Ashby. Use this to categorize and organize candidates with existing tags from the system. This action allows you to apply labels/tags to candidates for filtering, searching, and organizational purposes. Tags must already exist in the system - use LIST_CANDIDATE_TAGS to view available tags or CREATE_CANDIDATE_TAG to create new ones. The response includes the full updated candidate object when successful, showing the newly added tag in the candidate's tags array. If a candidate already has the tag, the operation will still succeed idempotently.
