# JsTopologyTransaction
## Properties
**update_id** | **String** | Assigned by the server. Useful for correlating logs. Must be a valid LedgerString (as described in ``value.proto``). Required |
**offset** | **i64** | The absolute offset. The details of this field are described in ``community/ledger-api/README.md``. It is a valid absolute offset (positive integer). Required |
**synchronizer_id** | **String** | A valid synchronizer id. Identifies the synchronizer that synchronized the topology transaction. Required |
**record_time** | **String** | The time at which the changes in the topology transaction become effective. There is a small delay between a topology transaction being sequenced and the changes it contains becoming effective. Topology transactions appear in order relative to a synchronizer based on their effective time rather than their sequencing time. Required |
**events** | [**Vec<models::TopologyEvent>**](TopologyEvent.md) | A non-empty list of topology events. Required: must be non-empty |
**trace_context** | Option<[**models::TraceContext**](TraceContext.md)> | | [optional]
