How it works
How it works Send personalized WhatsApp campaigns to hundreds of contacts imported directly from a Google Sheet. This workflow creates a contact group in MoltFlow, launches a bulk send job with smart anti-spam delays, and reports campaign progress — all in one click. You click "Execute" when ready to launch a campaign Contacts are read from your Google Sheet (phone, name, and optional custom message per contact) A custom group is created in MoltFlow with all valid contacts A bulk send job is launched — MoltFlow handles message delivery with smart delays to protect your WhatsApp number After 30 seconds, the workflow checks progress and shows a summary (sent, failed, remaining) Set up steps Setup takes about 5 minutes: Create a MoltFlow account and connect your WhatsApp by scanning the QR code Generate an API key from Sessions > API Keys tab (select the "Outreach" scope preset) Prepare your Google Sheet with columns: phone, name, message_override (optional) In n8n, connect your Google Sheets OAuth2 credential and your MoltFlow API Key (Header Auth with header name X-API-Key) Open the Read Contacts from Sheet node and paste your Google Sheet URL Open the Format Contacts code node and replace YOUR_SESSION_ID with your MoltFlow session ID Customize the default message template if needed Click Execute Workflow to launch Google Sheet format Your sheet needs these columns (headers in row 1): phone** — phone number with country code, digits only (e.g. 1234567890) name** — contact name message_override** — (optional) custom message for this contact; if empty, the default template is used Prerequisites A MoltFlow account with a connected WhatsApp session A Google Sheet with contact data MoltFlow API key with custom-groups:manage, bulk-send:manage, bulk-send:read scopes.
