Freshsales to Syspro integration — real-time, two-way sync

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

Change detection on Freshsales: Polling with updated-at filters through views; outbound webhooks can be configured via workflow automations. On Syspro: Polling; the ERP does not expose a change feed to external consumers. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.

On the Freshsales side: Deals, Tasks, Appointments, Notes, plus custom fields where Freshsales exposes them. On the Syspro side: GL journals, Warehouses, Customers, Suppliers. Stacksync auto-detects both schemas and converts types between the two systems.

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 Syspro: Where Syspro is the finance system of record: money status on the account; One customer master; Where Syspro manages people and org data: keep Freshsales aligned. Invoice and payment state from Syspro shows on the account in Freshsales, so reps see balances before promising the next order.

Freshsales: REST API. Authentication: API key sent as a Token authorization header. Syspro: E.net Solutions business objects, exposed over REST and WCF interfaces in SYSPRO 8. Authentication: SYSPRO operator credentials exchanged for a session token. Stacksync manages authentication, retries, and rate limits on both sides.
