• Node: OpenAI
  • Action: Creates a custom assistant named "Travel with us" Assistant using the gpt-4o-mini model.
  • Instructions:
    • Respond only using the provided document (e.g., agency-specific info).
    • Stay friendly, brief, and focused on travel-related queries.
    • Ignore irrelevant questions politely.
  • Credentials: Requires OpenAI API key.

2. Upload Agency Document

• Google Drive Node:
  • Action: Downloads a Google Doc as a PDF.
• OpenAI2 Node:
  • Action: Uploads the PDF to OpenAI with purpose: "assistants".
  • Output: Generates a file_id.

3. Update the Assistant with the Document

• OpenAI Node:
  • Action: Updates the assistant to include the uploaded file.

4. Chat Interaction

• Chat Trigger:
  • Activates when a message is received ("When chat message received").
• OpenAI Assistant Node:
  • Action: Uses the updated assistant to respond to user queries.
  • Memory: Window Buffer Memory retains chat context for coherent conversations.

Set Up Steps

1. Prepare the Document:

   • Store your travel agency guide in Google Drive (e.g., as a Google Doc).

3. Customize the Assistant:

   • Modify the instructions in the OpenAI node to reflect your agency’s needs.
   • Ensure the document includes FAQs, policies, and travel info.
