Can you integrate Microsoft Dynamics NAV with PostgreSQL?

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

Can the Microsoft Dynamics NAV–PostgreSQL sync run one-way instead of two-way?

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.

How do teams use the Microsoft Dynamics NAV and PostgreSQL integration?

Common patterns for Microsoft Dynamics NAV and PostgreSQL: Where Microsoft Dynamics NAV is the HR system of record: people data for internal systems; Controlled write-back; Read ERP records with a query. Worker and org records stay current in PostgreSQL for provisioning, access, and reporting systems that read from the database.

What should I know about the two APIs?

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. PostgreSQL: SQL wire protocol (PostgreSQL frontend/backend protocol). Authentication: Database credentials (connection string or parameters), with optional SSL root certificate upload and optional SSH tunnel (SSH user + host); a least-privilege DB user. Stacksync manages authentication, retries, and rate limits on both sides.

What makes PostgreSQL's data model different?

PostgreSQL: Logical decoding of the write-ahead log (wal_level=logical) provides row-level change capture without adding triggers to user tables. 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 Microsoft Dynamics NAV and PostgreSQL without custom code.

Is the Microsoft Dynamics NAV–PostgreSQL integration secure?

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 Microsoft Dynamics NAV and PostgreSQL records are not retained after a sync operation.

Why teams connect Microsoft Dynamics NAV and PostgreSQL

Give your engineers Microsoft Dynamics NAV's data in PostgreSQL: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors Vendors, Items, Sales Orders & Invoices, Purchase Orders from Microsoft Dynamics NAV into PostgreSQL and keeps both sides consistent in real time. Whatever Microsoft Dynamics NAV is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in PostgreSQL sync back into Microsoft Dynamics NAV with its validations respected.

Common use cases

Let an application write to its own database and have those rows appear as records in business systems in near real time
Consolidate data from several microservice databases into one operational Postgres store
Replicate G/L and ledger entries into a warehouse for consolidated finance reporting.
Keep inventory availability current in storefronts and customer portals.

Where Microsoft Dynamics NAV is the HR system of record: people data for internal systems

Worker and org records stay current in PostgreSQL for provisioning, access, and reporting systems that read from the database.

Controlled write-back

Choose exactly which tables and fields may flow from PostgreSQL back into Microsoft Dynamics NAV, keeping the ERP authoritative.

Read ERP records with a query

Records from Microsoft Dynamics NAV live in PostgreSQL as ordinary tables or collections, joinable with the rest of your data.

What you can sync between Microsoft Dynamics NAV and PostgreSQL

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Microsoft Dynamics NAV objects		PostgreSQL objects
Items Item cards and availability mirrored to ecommerce and planning systems.	⇄	Views Read-side projections used to expose joined or filtered data to a sync.
Sales Orders & Invoices Sales documents created from external orders and read back for posting status.	⇄	Materialized Views Precomputed result sets synced outward on a refresh schedule.
Purchase Orders Purchasing documents reconciled with receiving and vendor systems.	⇄	Schemas Namespaces that scope which tables a sync reads and writes.
G/L Entries Posted ledger entries replicated to warehouses for finance reporting.	⇄	Columns Field-level mapping targets; types are mapped to the connected system's field types.
Item Ledger Entries Inventory movement history read for stock and costing analytics.	⇄	Primary and Unique Keys Used as match keys for idempotent upserts and conflict resolution.
Dimensions Analytical codes carried on documents and entries for reporting splits.	⇄	JSONB Columns Hold semi-structured payloads such as nested SaaS objects or metadata.
