FAQ
How do I trigger a OpenAI Chat action from HTTP Request?
Most workflows in this list use either a HTTP Request webhook trigger (real-time) or a polling trigger (every N minutes). From there, downstream OpenAI Chat nodes handle the action. Open any workflow's detail page to see the exact node graph.
Do I need both a HTTP Request and a OpenAI Chat account?
Yes — n8n connects to each integration via your own credentials. AutomationFlows strips credential IDs before publishing, so you'll add your own.
Are these HTTP Request → OpenAI Chat workflows free?
Yes — every workflow on AutomationFlows is free to browse and copy. Pro adds a multi-signal QualityScore on every workflow plus bulk JSON download.
