Hyperline to Kustomer integration — real-time, two-way sync

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

Change detection on Hyperline: Webhooks for billing events, with polling as a fallback. On Kustomer: Outbound webhooks on record events, plus polling for backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.

On the Hyperline side: Credit notes, Customers, Subscriptions, Products / prices, plus custom fields where Hyperline exposes them. On the Kustomer side: Tags, Notes, Customers, Conversations. 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 Hyperline and Kustomer: Collections with context; Where Kustomer tracks deals: closed-won creates the finance record; Payment status on the account. Finance sees the account owner and relationship history from Kustomer when chasing a balance, and sales sees that the chase is happening.

Hyperline: REST API. Authentication: API key (bearer token). Kustomer: REST API. Authentication: API key used as a bearer token, scoped by role. Stacksync manages authentication, retries, and rate limits on both sides.
