The workflow triggers upon a new form submission containing file data. 2. It extracts the file contents and sends them to an external API to calculate a repair score. 3. The workflow parses the AI score and saves the lead details into GoHighLevel. 4. Finally, it retrieves the original image and sends a summary notification to the lead technician via WhatsApp.\n\n### Setup steps\n\n- Configure the Form Trigger to receive appropriate file fields.\n- Ensure the AI API credentials are set for the repair score calculation.\n- Connect your GoHighLevel account to save lead information.\n- Authenticate your WhatsApp Business account for notifications.\n\n### Customization\n\nYou can modify the notification message template to include additional CRM fields or change the communication channel from WhatsApp to Email." }, "typeVersion": 1 }, { "id": "dfaa406d-19a8-4cf2-931f-da526416d57a", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ 1136, 96 ], "parameters": { "color": 7, "width": 464, "height": 272, "content": "## Trigger and extract input data\n\nReceives input and extracts file data." }, "typeVersion": 1 }, { "id": "f3264a8b-2d29-4435-ba26-7a4fd432db61", "name": "Sticky Note2", "type": "n8n-nodes-base.stickyNote", "position": [ 1680, 96 ], "parameters": { "color": 7, "width": 384, "height": 272, "content": "## Calculate automated repair score\n\nPerforms AI analysis on extracted data." }, "typeVersion": 1 }, { "id": "bfd1321a-c7ab-4d1d-b1ab-71a680a18d16", "name": "Sticky Note3", "type": "n8n-nodes-base.stickyNote", "position": [ 2112, 96 ], "parameters": { "color": 7, "width": 704, "height": 288, "content": "## Update CRM and notify technician\n\nSaves result to CRM and notifies technician." }, "typeVersion": 1 }, { "id": "cd263103-ba33-46cd-9af5-7ae34d1a4b18", "name": "When Form Submitted", "type": "n8n-nodes-base.formTrigger", "position": [ 1184, 208 ], "parameters": { "options": { "customCss": ":root {\n\t/* Fonts */\n\t--font-family: 'Inter', 'Helvetica Neue', Helvetica, Arial, sans-serif;\n\t--font-weight-normal: 400;\n\t--font-weight-bold: 600;\n\t--font-size-body: 12px;\n\t--font-size-label: 14px;\n\t--font-size-test-notice: 12px;\n\t--font-size-input: 14px;\n\t--font-size-header: 22px;
