Freshworks CRM to Kustomer integration — real-time, two-way sync

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

Common patterns for Freshworks CRM and Kustomer: Divisional or regional split; Where both track pipeline: deal visibility across systems; Post-acquisition consolidation. Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.

Freshworks CRM: REST API. Authentication: API key sent as a Token authorization header. Kustomer: REST API. Authentication: API key used as a bearer token, scoped by role. Stacksync manages authentication, retries, and rate limits on both sides.

Freshworks CRM: Contacts and accounts expose lifecycle stages and custom fields through the API, so one record serves both sales and marketing workflows. Kustomer: Custom object types are called Klasses, and they are the standard mechanism for landing external data like orders and subscriptions where agents work. Stacksync's field mapping accounts for these differences between Freshworks CRM and Kustomer 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 Freshworks CRM and Kustomer records are not retained after a sync operation.

Stacksync pricing is usage-based and starts at $1,000/month, including the managed Freshworks CRM and Kustomer connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Freshworks CRM–Kustomer integration in-house.
