Automated Trello Board Summarization with GPT-5-Nano

This workflow pulls a Trello board → lists → cards , maps key fields (board, list, task names/descriptions), and asks OpenAI to summarize the board.

3. In n8n → Credentials → New → Trello API , paste API Key and Token , save.
4. Open each Trello node (Get Board , Get Lists , Get Cards) and select your Trello credential.
