Can you integrate Folk CRM with Kustomer?

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

Can the Folk CRM–Kustomer 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 Folk CRM and Kustomer integration?

Common patterns for Folk 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.

What should I know about the two APIs?

Folk CRM: 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.

What makes Folk CRM's data model different?

Folk CRM: Custom fields are defined per group, which means field mappings can differ across groups within the same workspace. Kustomer: API keys are issued as role-scoped bearer tokens, so integration access can be limited to the specific object types a sync touches. Stacksync's field mapping accounts for these differences between Folk CRM and Kustomer without custom code.

Is the Folk CRM–Kustomer 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 Folk CRM and Kustomer records are not retained after a sync operation.

Why teams connect Folk CRM and Kustomer

Run Folk CRM and Kustomer side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.

Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.

Stacksync syncs Reminders, People, Companies, Groups in Folk CRM with Notes, Customers, Conversations, Messages in Kustomer in real time and in both directions, with field-level mapping and matching on identifiers you choose. Update a record in either CRM and the other reflects it within seconds.

Common use cases

Keep folk and a billing or customer success tool aligned on company records as deals close.
Sync folk people and companies with a marketing or outbound tool so outreach lists stay current.
Mirror conversations and satisfaction data into a warehouse for support analytics and agent performance reporting
Keep customer attributes updated from billing systems so routing rules and SLAs reflect account value

Divisional or regional split

Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.

Where both track pipeline: deal visibility across systems

Deal stage and value on shared accounts stay visible from either CRM.

Post-acquisition consolidation

Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.

What you can sync between Folk CRM and Kustomer
