Kustomer to SQL Server integration — real-time, two-way sync

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

On the Kustomer side: Conversations, Messages, Companies, Custom Objects (Klasses), plus custom fields where Kustomer exposes them. On the SQL Server side: Databases, Schemas, Tables, Views. 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 Kustomer and SQL Server: Query the CRM like a database; Product events onto CRM records; Internal tools without API code. Accounts, contacts, and custom objects from Kustomer become tables in SQL Server you can join with application data directly.

Kustomer: REST API. Authentication: API key used as a bearer token, scoped by role. SQL Server: SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers. Authentication: Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page. Stacksync manages authentication, retries, and rate limits on both sides.

Kustomer: API keys are issued as role-scoped bearer tokens, so integration access can be limited to the specific object types a sync touches. SQL Server: Change Tracking is a lower-overhead alternative that records which rows changed, but not intermediate values, so it suits net-change syncs. Stacksync's field mapping accounts for these differences between Kustomer and SQL Server without custom code.
