user3029: In the Ardor platform, there are different types of transactions. What do each number type represent? Some are asset transfers, send transaction, and voting. Where can I find a list of these types of transactions? 


user18874: Use the getConstants API and check the "transactionSubTypes" JSON array for a mapping of transaction types and sub types to their display name.
"transactionSubTypes": {
    "AssetIssuance": {
        "isPhasable": true,
        "subtype": 0,
        "mustHaveRecipient": false,
        "name": "AssetIssuance",
        "canHaveRecipient": false,
        "isGlobal": true,
        "type": 2,
        "isPhasingSafe": true
