SaveConnectorCustomerGroupsCommandRequestInput

Declaratively replaces the complete set of customer-group mappings of a connector account and pushes the resulting mapping live to the Connector endpoint. The request describes the full desired state - provided assignments are upserted and every mapping not contained in the request is cleared. An EndpointId that is neither already mapped nor currently reported by the Connector endpoint (stale data) is silently ignored, exactly as if it had not been submitted. Persistence of the resulting write always succeeds independently of the later live push outcome; a failed or timed-out live push is reported via LiveSyncStatus/LiveSyncError but does not roll back the persisted assignments or change the response code. This command has no IsDefault input - a customer group’s default flag, like its display name, is reported by the Connector endpoint itself; it is never accepted from or echoed back with authority by this write path, so a GET-modify-PUT round trip cannot change or need to preserve it. For an EndpointId not already mapped, EndpointName/IsDefault are instead resolved with one live read from the Connector endpoint before anything is persisted - unlike the later live push, a failure of this live read does fail the whole request (502/504) and persists nothing, because it is needed to build a valid response. - Request
