Get events by event handle This API uses the given account `address`, `eventHandle`, and `fieldName` to build a key that can globally identify an event types. It then uses this key to return events emitted to the given account matching that event type.

Parameters:

  • address - Hex-encoded 32 byte Aptos account, with or without a 0x prefix, for which events are queried. This refers to the account that events were emitted to, not the account hosting the move module that emits that event type.
  • eventHandle - Name of struct to lookup event handle e.g. 0x1::account::Account
  • fieldName - Name of field to lookup event handle e.g. withdraw_events
  • start - Starting sequence number of events. If unspecified, by default will retrieve the most recent
  • limit - Max number of events to retrieve. If unspecified, defaults to default page size
  • cancelToken - A CancelToken that can be used to cancel the operation
  • headers - Can be used to add additional headers to the request
  • extras - Can be used to add flags to the request
  • validateStatus - A ValidateStatus callback that can be used to determine request success based on the HTTP status of the response
  • onSendProgress - A ProgressCallback that can be used to get the send progress
  • onReceiveProgress - A ProgressCallback that can be used to get the receive progress

Returns a Future containing a Response with a BuiltList<VersionedEvent> as data Throws DioError if API call or serialization fails
