Freshsales to Microsoft Dynamics NAV integration — real-time, two-way sync

Yes. Stacksync provides a managed, real-time two-way integration between Freshsales and Microsoft Dynamics NAV: authenticate both systems, choose the objects to sync (such as Freshsales's Tasks and Appointments), map fields visually, and changes propagate both ways in milliseconds — no code required.

Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.

Common patterns for Freshsales and Microsoft Dynamics NAV: One customer master; Where Microsoft Dynamics NAV manages people and org data: keep Freshsales aligned; Where Microsoft Dynamics NAV handles order-to-cash: closed-won flows through. Where both systems keep customer or organization records, corrections in either propagate to the other, ending dual maintenance.

Freshsales: REST API. Authentication: API key sent as a Token authorization header. Microsoft Dynamics NAV: SOAP and OData web services published from NAV pages and codeunits; direct SQL Server access on-premises. Authentication: Windows authentication or NavUserPassword credentials. Stacksync manages authentication, retries, and rate limits on both sides.

Freshsales: List access runs through views (saved filters): the API returns contacts or deals per view, which shapes how full extracts and incremental pulls are structured. Microsoft Dynamics NAV: Business logic lives in C/AL codeunits; writes through page services run that validation, while raw SQL writes bypass it and are riskier. Stacksync's field mapping accounts for these differences between Freshsales and Microsoft Dynamics NAV without custom code.

Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Freshsales and Microsoft Dynamics NAV records are not retained after a sync operation.
