# createImportSync

> Create an import job definition that continuously syncs tenant field schemas, tenants, and customers from a connected external service (Attio, HubSpot, or Salesforce). Only one enabled import job definition can exist per service authorization at a time; calling this when one is already enabled returns an error. Use updateImportJobDefinition to disable an existing definition before creating a new one.
