What this workflow does
This AI workflow has 19 nodes and runs on a schedule (every day at 05:00). Along the way it connects OpenAI Chat Model, Slack and Google Drive.
How it runs
Trigger: On a schedule (every day at 05:00).
- Normalize Poll Window (Edit Fields (Set)): sets or maps fields
- Fetch Segments Due & Inspector Notes (HTTP Request): calls an HTTP API (GET)
- Classify Defect Severity (Text Classifier): classifies text into categories with AI, with model: Classifier Model
- Tag No Defect (Edit Fields (Set)): sets or maps fields
- Tag Minor (Edit Fields (Set)): sets or maps fields
- Tag Serious (Edit Fields (Set)): sets or maps fields
- Tag Immediate Halt (Edit Fields (Set)): sets or maps fields
- Compute FRA Speed Restriction & Remedial Timeframe (Code): runs custom JavaScript code
- Requires Immediate Tag-Out? (If): checks a condition and branches into true / false
- Request Supervisor Tag-Out Approval (Slack): send and wait for a reply (message)
…plus 7 more steps. See the full node list below.
