Why teams connect Gainsight and Kustomer
Sync what happens in Gainsight with the customer records in Kustomer, in real time and in both directions.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever Gainsight holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Scorecard Fact, Timeline Activity, Success Plan, Task and Playbook in Gainsight to Tags, Notes, Customers, Conversations in Kustomer with bi-directional, real-time sync. Activity and record changes in Gainsight update the matching contact or account in Kustomer, and CRM data flows the other way wherever Gainsight can store and use it.
Common use cases
- 01 Keep Relationship records aligned with a billing system or ERP so multi-product customers map to the correct contracts and invoices.
- 02 Read Timeline Activities and Success Plan objectives into a reporting database for churn, QBR, and CSM-productivity dashboards.
- 03 Sync customers bi-directionally with the CRM and ERP so agents see deal, billing, and subscription context on the timeline
- 04 Push order and shipment records from commerce systems into Kustomer custom objects so agents answer order-status questions without switching tools
Common sync patterns
Where Gainsight processes payments
Charges, refunds, and subscription changes appear on the account in Kustomer, so revenue context lives with the relationship.
Where Gainsight can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Kustomer sync into Gainsight, so people working there have the context without switching tools.
Where Gainsight handles support or shared inboxes
Tickets and conversations attach to the right contact and account in Kustomer, so sales sees open issues before the next call.
What you can sync between Gainsight and Kustomer
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.
| Gainsight objects | Kustomer objects | How this pairing syncs | |
|---|---|---|---|
| Company Customer/account master in Gainsight CS; two-way synced with CRM and warehouse customer tables to keep ARR, owner, and renewal fields aligned. | Companies Organization records group customers and map to CRM accounts. | Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions. Custom fields on either side are included in the mapping. | |
| Custom Objects Org-specific MDA tables with the __gc suffix; discoverable via the Describe API so field mappings can be generated automatically. | Notes Internal annotations carry context alongside synced conversations. | Custom Objects is specific to Gainsight and Notes to Kustomer — each maps to any object or custom field on the other side. | |
| Person (People) Contacts associated to companies through the Company Person junction; synced two-way with CRM contacts and warehouse person records. | Customers The central record whose timeline aggregates every interaction; external attributes sync onto it. | Person (People) is specific to Gainsight and Customers to Kustomer — each maps to any object or custom field on the other side. | |
| Relationship Sub-units within a company for multi-product or multi-team accounts; synced so each maps to the right contract in billing or an ERP. | Conversations Support threads across channels sync outward for analytics and CRM context. | Relationship is specific to Gainsight and Conversations to Kustomer — each maps to any object or custom field on the other side. | |
| CTA (Call to Action) Risk and expansion alerts that drive CSM plays; often synced to ticketing or project tools so follow-up work is tracked where teams operate. | Messages Individual messages within conversations support full-thread replication. | CTA (Call to Action) is specific to Gainsight and Messages to Kustomer — each maps to any object or custom field on the other side. | |
| Scorecard Fact Health scores and measures per Company or Relationship; usage metrics from a warehouse are written in so scores reflect live telemetry. | Custom Objects (Klasses) Structured external records such as orders and subscriptions synced in to appear on the customer timeline. | Scorecard Fact is specific to Gainsight and Custom Objects (Klasses) to Kustomer — each maps to any object or custom field on the other side. |
How changes propagate between Gainsight and Kustomer
Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.
Gainsight Kustomer Interval-based propagation
DetectionStacksync polls Gainsight for changes on an incremental schedule, reading only records changed since the previous pass. Polling on the ModifiedDate (GS Modified Date) system field, which is filterable and sortable on every object.
DeliveryEach detected change is written to Kustomer through its API, with automatic retries and rate-limit backoff.
Kustomer Gainsight Sub-second propagation
DetectionKustomer notifies Stacksync of record changes through webhook events. Outbound webhooks on record events, plus polling for backfill.
DeliveryEach detected change is written to Gainsight through its API, with automatic retries and rate-limit backoff.
Rate-limit considerations
- Gainsight: Synchronous APIs are capped near 100 calls/min and 50,000/day; the asynchronous Bulk API allows 10 calls/hour and 100/day. Both are fixed-window limits, and the applicable per-hour and per-day limits are returned in the x-ratelimit-limit response header.
- Kustomer: Subject to the platform's API rate limits.

FAQ
Gainsight and Kustomer integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Gainsight and Kustomer: authenticate both systems, choose the objects to sync (such as Gainsight's Company and Custom Objects), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Gainsight and Kustomer connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Gainsight–Kustomer integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Gainsight and Kustomer. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Gainsight: Polling on the ModifiedDate (GS Modified Date) system field, which is filterable and sortable on every object; Rules Engine Real-Time Rules can optionally push specific object events (e.g., a Company stage change) to an external endpoint. 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 Gainsight side: Scorecard Fact, Timeline Activity, Success Plan, Task and Playbook, plus custom fields where Gainsight 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.
