n8n Salesforce + Gmail Deal Knowledge Graph to Neo4j

Turn Salesforce + Gmail interactions into a searchable Neo4j knowledge graph

This n8n workflow runs every 6 hours to pull your Salesforce contacts, accounts, and opportunities, enrich them with recent Gmail messages and Google Calendar meetings, then writes a deal + stakeholder knowledge graph into Neo4j for fast relationship analysis.

What this workflow does

• Scheduled sync: executes on a 6-hour schedule.
• Normalize Salesforce data: fetches Contacts, Accounts, and Opportunities from Salesforce and standardizes them into consistent records.
• Enrich with Gmail: builds a Gmail search query from the first 20 unique Salesforce contact email addresses, retrieves matching Gmail messages from the last 30 days, and normalizes email metadata.
• Enrich with Google Calendar: pulls Google Calendar events using a 30-day lookback and 30-day lookahead, then normalizes them into meeting records with attendee details.
• Compute engagement profiles: combines normalized Salesforce + Gmail + Calendar data to produce a per-contact relationship profile, including engagement metrics and interaction history.
• Write to Neo4j as a graph: creates graph nodes (Contact, Account, Opportunity, Email, Meeting) and relationship edges such as BELONGS_TO, OWNS, INVOLVED_IN, SENT_OR_RECEIVED, and ATTENDED.
• Neo4j persistence: inserts nodes first, then writes relationships using the Neo4j Query API.

Use cases

• Analyze which contacts are most engaged with specific Opportunities based on email and meeting activity.
• Map stakeholder involvement across accounts using graph traversal in Neo4j.
• Build a relationship intelligence layer for SaaS sales teams using Salesforce + Gmail + Calendar data.

Technical details

• Auth/Connections: add credentials for Salesforce, Gmail, Google Calendar, and Neo4j (HTTP Basic Auth for the Neo4j Query API).
• Neo4j setup: update the Neo4j Query API URLs to your Neo4j AuraDB endpoint and database path.
