What it does
Workflow Overview This workflow automates the creation and management of a custom OpenAI Assistant for a travel agency ("Travel with us"), leveraging Google Drive for document storage. --- How It Works 1. Create the OpenAI Assistant - 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 fileid. 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). - Update the Google Drive node with your document’s ID. 2. Configure Credentials: - Google Drive: Connect via OAuth2 (googleDriveOAuth2Api). - OpenAI: Add your API key to all OpenAI nodes. 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. 4. Test the Workflow: - Trigger manually ("Test workflow") to create the assistant and upload the file. - Send a chat message (e.g., "What are your travel packages?") to test responses. --- Dependencies - Google Drive Account: To store and retrieve the agency document. - OpenAI API Access: For assistant creation and file uploads. --- Need help customizing?
