A map of token IDs that you want to retrieve data from.
Include Metadata (Boolean)
Enable this flag if you want to receive token metadata in the response.
Supplies (SeqGetTokenSuppliesMapReturn Struct)
Contains a SeqTokenSupply array for each specified ID in the ‘Token Map’. ” + “Each element contains a ‘supply’ value. If ‘Include Metadata’ is set to true, token metadata is also included.
Get Transaction History Retrieve the transaction history for a wallet- or token address.
For example, here we get all transactions for the current user.
const TSuccessCallback < FSeqGetTransactionHistoryReturn > OnApiSuccess = [ this , OnSuccess ]( const FSeqGetTransactionHistoryReturn & TransactionHistory ) { }; const FFailureCallback OnApiFailure = [ this , OnFailure ]( const FSequenceError & Error ) { }; FSeqGetTransactionHistoryArgs Args; Args . filter = Filter; Args . page = Page; Args . includeMetaData = IncludeMetadata; USequenceIndexer * Indexer = NewObject < USequenceIndexer >(); Indexer -> GetTransactionHistory ( SequenceSdk :: GetChainId (), Args, OnApiSuccess, OnApiFailure);
Account Address (FString)
