Steps
CSMS calls GetLocalListVersionRequest to read the station's current localListVersion (0 means the list is empty).
CSMS builds a SendLocalListRequest with a new versionNumber and updateType Full (complete replacement) or Differential (add/update/remove specific entries), each localAuthorizationListEntry containing an idToken and optional idTokenInfo.
For large fleets, split Full updates across the max list size the station's device model advertises, since a single message can exceed transport limits.
Station applies the update and responds SendLocalListStatus: Accepted, Failed, or VersionMismatch — VersionMismatch means the CSMS's versionNumber doesn't follow the station's current version and the whole update is rejected.
On VersionMismatch, re-run GetLocalListVersion to resync before retrying, rather than blindly incrementing the version and resending.
Known gotchas
Differential updates are cumulative against the station's list state, not against what the CSMS thinks it last sent — if a station reboots and reverts to a persisted older version, later differential updates from the CSMS's newer baseline will VersionMismatch until a Full resync happens.
Local list authorization only takes effect if the station's offline-authorization configuration variables are enabled — teams frequently push a list successfully and then find offline transactions still get rejected because that variable was never set.
The station may cap the max number of list entries far below what a large-fleet RFID population needs, requiring server-side pruning or per-station list tailoring.
