Workflow Overview

A 4-node linear pipeline that runs automatically when a business card photo is shared in Slack:

Fetch Image → Analyse Image → Extract Details → Add to CRM

Node Breakdown

1. Fetch Image

• Type: Slack Trigger
• Event: file_share in the #connections channel
• Behaviour: Listens for new file uploads and downloads the attached image automatically

2. Analyse Image

• Type: Google Gemini (LangChain)
• Model: gemini-3-flash-preview
• Input: Binary image from the Slack trigger
• Behaviour: Sends the image to Gemini with a structured prompt requesting a flat JSON object with the following fields:

full_name · job_title · company · email · phone · website · address · linkedin · twitter · other_social · notes

• Prompt rules:
  • Every field must be present (null if not on card)
  • If multiple phone numbers exist, the main one goes in phone, the rest in notes
  • Any extra card text goes in notes
  • Output must be raw JSON only - no markdown, no code fences

3. Extract Details

• Type: Code (JavaScript)
• Behaviour: Parses the Gemini response text into a usable JSON object:
  • Strips any markdown code fences that Gemini may still include
  • Converts all null values to empty strings (prevents errors in downstream Notion writes)
  • Returns a clean flat object ready for property mapping

4. Add to CRM

• Type: Notion (Create Database Page)
