This AI workflow has 33 nodes and runs manually, when you click “Execute workflow” (plus 2 other triggers). Along the way it connects OpenAI Chat Model and Slack.
How it runs
Trigger: Manually, when you click “Execute workflow” (plus 2 other triggers).
- Create a data table (Data table): create (table)
- Get many workflows (n8n): uses n8n
- If: checks a condition and branches into true / false
- Get known workflows (Data table): get
- Merge: merges the data from its input branches
- Switch: routes items into 2 branches
- Loop Over Items (Loop Over Items (Split in Batches)): loops over the items in batches
- Disable scan (Data table): update
- Enable scan (Data table): update
- Filter: keeps only the items that match a condition
…plus 16 more steps. See the full node list below.
Services it uses
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
- Still check Slack Trigger requires a signing secret on the Slack API credential (Slack Trigger).
