Quick overview This workflow captures details via an n8n form, uses OpenAI to generate structured proposal copy, and then produces a client-ready proposal either by filling a Google Slides template or by creating a PandaDoc document with pricing, before emailing the proposal to the prospect via Gmail. How it works Triggers when a sales rep submits the built-in n8n “Sales Call Logging Form” with the prospect and deal details. Sends the submitted company, problem, solution, scope, timeline, and cost to OpenAI (GPT‑4o) to generate proposal fields as a single JSON object. For the PandaDoc path, creates a PandaDoc document from a template via the PandaDoc API and injects the OpenAI-generated text plus a pricing table based on the form’s Cost value. Emails the PandaDoc proposal to the prospect using Gmail. For the Google Slides path, copies a proposal template in Google Drive and names it using the OpenAI-generated proposal title. Replaces placeholder tokens in the copied Google Slides presentation with the OpenAI-generated proposal sections. Emails the Google Slides proposal link to the prospect using Gmail.

Handle WhatsApp support text and voice messages with OpenAI GPT-5 Mini
Quick overview This workflow responds to incoming WhatsApp Business messages, handling both text and voice notes by transcribing audio with OpenAI and replying with an OpenAI chat agent that uses per-contact conversation memory and answers only from the business information you provide. How it works Triggers when a new WhatsApp message is received. Routes the incoming message by type, sending text messages directly to the support flow, audio messages to a voice-transcription flow, and other message types to a fallback reply. For voice notes, retrieves the WhatsApp media URL, downloads the audio file, and transcribes it to text with OpenAI. Sends the customer’s text (original or transcribed) to an OpenAI chat agent configured to answer only using your provided business information. Stores and reuses a per-contact conversation history keyed by the sender’s WhatsApp number to maintain context across messages. Sends the agent’s response back to the customer as a WhatsApp text message. Setup Connect WhatsApp Business Cloud credentials for both receiving messages (trigger) and sending replies, and ensure your WhatsApp webhook is configured to point to the trigger URL.

Verify Japanese invoice registration numbers from Gmail using Gemini, NTA API, Sheets and Slack
Quick Overview This workflow monitors Gmail for unread invoice emails with PDF attachments, extracts invoice details with Google Gemini, verifies Japanese qualified invoice registration numbers against the National Tax Agency (NTA) Invoice Web-API, logs results to Google Sheets, and sends Slack alerts for invalid, missing, or inconclusive checks. How it works Polls Gmail hourly for unread emails matching “has:attachment invoice” and downloads the first attachment. Extracts text from the attached invoice PDF. Uses Google Gemini to parse the invoice text into structured fields such as the T-registration number, issuer name, invoice date, and amounts. Normalizes and validates the registration number to ensure it matches the required “T + 13 digits” format. If the format is valid, calls the NTA Invoice Web-API to verify the registration number and interprets the response as valid, invalid, or not found. Appends the invoice details and verification status to a Google Sheets worksheet. Routes the outcome by sending the appropriate Slack alert for invalid/not found/inconclusive results or marking the invoice email as read when the number is valid.
