It waits 20 seconds between status checks, returns the deck link and project PID on success, and stops with an error if Encelade reports a failed generation.\n\n### Setup steps\n\n- Configure the Encelade credentials/API key used by the Encelade nodes.\n- Set the prompt and any deck generation options in the \u201cGenerate Presentation Deck\u201d node.\n- Ensure the \u201cCheck Deck Status\u201d node uses the session ID returned by \u201cGenerate Presentation Deck\u201d.\n- Verify the IF conditions in \u201cIf Deck Ready\u201d and \u201cIf Generation Failed\u201d match the phase values returned by Encelade.\n\n### Customization\n\nAdjust the wait interval, retry behavior, prompt content, and returned fields such as deckLink or projectPid to fit your deck generation process."

About this workflow
This workflow starts a presentation generation job in Encelade from a prompt and outline hints, polls Encelade for completion, and outputs the finished deck link (or stops with an error if generation fails). Starts when you manually execute the workflow in n8n. Sends the topic,…
