Request

Request Structure

{ // parameters common for all requests "MethodApi" : "string_value", // API method name to form and process a transaction "PublicKey":"string_value", // Sender public key in Base58 "ReceiverPublicKey":"string_value", // Recipient public key in Base58 “Amount”:decimal, // Transaction amount "Fee":decimal, // Maximum fee approved by the user "SmartContractSource":"String_value", //Source code of smart contract “UserData”:”string_value” // If needed extra information can be stored inside UserData }

Request Parameters

MethodApi: string value - it’s vital to specify the API method to pack the transaction: "TransferToken", "TransferCs", "Delegation", "SmartDeploy", "SmartMethodExecute";

PublicKey: string_value - sender public key in base58

ReceiverPublicKey: string_value - recipient public key in base58

Amount: decimal - transaction amount as a decimal or integer number

Fee: decimal - maximum fee approved by the user as a decimal or integer number

UserData: string_value - data the user sent with the transaction including the data about deployment and initiation of a smart contract

Response
