acc-service-sdk 1.2.3

acc-service-sdk for C#

1) Installation

See nuget package) https://www.nuget.org/packages/acc-service-sdk

2) Features

A standard development kit provided for interworking with a decentralized loyalty point system. This SDK can be used in the following places.

1. It can be used when implementing the function of delivering purchase information paid by a KIOSK or POS.
2. It can be used when implementing the ability to purchase products using loyalty points.
3. It can be used when implementing a method in which partners deposit tokens and then provide points to users.
4. Provides information on shops registered with the settlement manager and the ability to withdraw settlement money into tokens.

3) How to save purchase data

See API Docs - https://save.test.acccoin.io/docs/ See Sample Code https://github.com/acc-coin/acc-service-sdk/blob/v0.x.x/csharp/sample/Sample/SavePurchaseClientSample.cs

This is a function used by partners that support the payment system.
The test net of the loyalty system is ready.
You can proceed with the development using the test net and switch to the main net at the time the development is completed.
Please create a wallet to be used for this feature, and forward the address of the wallet to the operations team of the loyalty system.
The private key of the wallet, which can be used on testnet, is " 0x8acceea5937a8e4bb07abc93a1374264dd9bd2fc384c979717936efe63367276".
Please make the wallet of the main net yourself and deliver only its address to the operation team. The system adds purchase information received from a trusted partner to the block. Validators verify this. For verified data, the system gives the buyer a percentage of the purchase amount as points.

3.1) Create Client Module

var SavePurchaseClient client = new SavePurchaseClient(
    NetWorkType.TestNet, 
    "0x8acceea5937a8e4bb07abc93a1374264dd9bd2fc384c979717936efe63367276", // The private key of wallet
    "0x85EeBb1289c0d0C17eFCbadB40AeF0a1c3b46714" //  The address of wallet, This is the address where token assets are stored
    );

3.2) Save New Purchase Data

var purchaseId = CommonUtils.GetSamplePurchaseId();
var timestamp = CommonUtils.GetTimeStamp();
await client.SaveNewPurchase(
        purchaseId, 
        timestamp,
        0,
        "10000",
        "10000",
        "php",
        shopId,
        userAccount,
        "",
        new PurchaseDetail[]{ new PurchaseDetail("2020051310000000", "10000", 10) }
    );

3.3) Save Cancel Purchase Data

await client.SaveCancelPurchase(purchaseId, timestamp, 3600);

4) How to use loyalty points

See API Docs - https://relay.test.acccoin.io/docs/
See Sample Code https://github.com/acc-coin/acc-service-sdk/blob/v0.x.x/csharp/sample/Sample/PaymentClientSample.cs

This is a necessary function to build a point payment system.
Please create a wallet to be used for payment, and forward the address of the wallet to the operations team of the loyalty system.
The private key of the wallet, which can be used on testnet, is " 0x8acceea5937a8e4bb07abc93a1374264dd9bd2fc384c979717936efe63367276".
Please make the wallet of the main net yourself and deliver only its address to the operation team.

4.1) Create Client for Payment

// This is the private key of the wallet to be used for payment.
var privateKeyForPayment = "0x8acceea5937a8e4bb07abc93a1374264dd9bd2fc384c979717936efe63367276";
var paymentClient = new PaymentClient(NetWorkType.TestNet, privateKeyForPayment);

4.2) Implement Event Listener

public class TestEventListener : ITaskEventListener
{
    public void OnNewPaymentEvent(
        string type,
        int code,
        string message,
        long sequence,
        PaymentTaskItem paymentTaskItem
    )
    {
        Console.WriteLine($"  -> OnNewPaymentEvent {type} - {code} - {message} - {sequence}");
    }

    public void OnNewShopEvent(
        string type,
        int code,
        string message,
        long sequence,
        ShopTaskItem shopTaskItem
    )
    {
        Console.WriteLine($"  -> OnNewShopEvent {type} - {code} - {message} - {sequence}");
    }
}

4.3) Create Event Collector

var listener = new TestEventListener();
collector = new TaskEventCollector(paymentClient, listener);

4.4) Start Event Collector

collector.Start();

4.5) Open New Payment

var purchaseId = CommonUtils.GetSamplePurchaseId();
var paymentItem = await paymentClient.OpenNewPayment(
    purchaseId,
    temporaryAccount,
    Amount.Make("1_000").Value,
    "php",
    shopId,
    terminalId
);

4.6) Close New Payment

await paymentClient.CloseNewPayment(paymentItem.PaymentId, true);

4.7) Open Cancel Payment

await paymentClient.OpenCancelPayment(paymentItem.PaymentId, terminalId);

4.8) Close Cancel Payment

await paymentClient.CloseCancelPayment(paymentItem.PaymentId, true);

4.9) Stop Event Collector

collector.Stop();

5) How to provide loyalty points

See API Docs - https://relay.test.acccoin.io/docs/
See Sample Code https://github.com/acc-coin/acc-service-sdk/blob/v0.x.x/csharp/sample/Sample/ProviderClientSample.cs

This is the functionality you need to provide points.
You first need to deposit more than 100,000 tokens through the app.
And you have to ask the system operation team for a partner.
You must register first in your app.
And if you register the agent's address, you don't have to provide the private key of the wallet with the assets.~~

5.1) Create Client for provide without agent

If the agent is not used, the private key of the provider in which the asset is stored should be provided to the development team

var providerClient = new ProviderClient(NetWorkType.TestNet,
    "0x70438bc3ed02b5e4b76d496625cb7c06d6b7bf4362295b16fdfe91a046d4586c");

5.2) Provide to wallet address without agent

var receiver = "0xB6f69F0e9e70034ba0578C542476cC13eF739269";
var amount = Amount.Make("100").Value;
await providerClient.ProvideToAddress(providerClient.Address, receiver, amount);

5.3) Provide to phone number hash without agent

var phoneNumber = "+82 10-9000-5000";
var amount = Amount.Make("100").Value;
await providerClient.ProvideToPhone(providerClient.Address, phoneNumber, amount);

5.4) Create Client for provide with agent

With agent, you only need to provide the address of the provider to the development team.

var providerAddress = "0x64D111eA9763c93a003cef491941A011B8df5a49";
var agentClient = new ProviderClient(NetWorkType.TestNet,
    "0x44868157d6d3524beb64c6ae41ee6c879d03c19a357dadb038fefea30e23cbab"); // address: 0x3FE8D00143bd0eAd2397D48ba0E31E5E1268dBfb

5.5) Provide to wallet address with agent

var providerAddress = "0x64D111eA9763c93a003cef491941A011B8df5a49"
var receiver = "0xB6f69F0e9e70034ba0578C542476cC13eF739269";
var amount = Amount.Make("100").Value;
await agentClient.ProvideToAddress(prviderAddress, receiver, amount);

5.6) Provide to phone number hash with agent

var providerAddress = "0x64D111eA9763c93a003cef491941A011B8df5a49"
var phoneNumber = "+82 10-9000-5000";
var amount = Amount.Make("100").Value;
await agentClient.ProvideToAddress(prviderAddress, phoneNumber, amount);

6) How to settlement of shops

See API Docs - https://relay.test.acccoin.io/docs/
See Test Code https://github.com/acc-coin/acc-service-sdk/blob/v0.x.x/csharp/test/Test/SettlementClientUsingAgent.cs

The shop that acts as an agent for the settlement of shops is the settlement-shop.
This SDK provides the features you need for this settlement-shop.
First, the settlement-shop needs to secure the store ID by installing the shop app.
And register the address of the settlement agent and withdrawal agent on the app.
The wallet's private key of the settlement agent is managed by the development team, and the wallet's private key of the withdrawal agent is managed by the accounting team.
Owners of settlement-shop can set up these two addresses.

6.1) Create Client for settlement-shop

var ownerPrivateKey = "0xd72fb7fe49fd18f92481cbee186050816631391b4a25d579b7cff7efdf7099d3";
var managerShopId = "0x000108bde9ef98803841f22e8bc577a69fc47913914a8f5fa60e016aaa74bc86";
var settlementClientForManager = new SettlementClient(network, ownerPrivateKey, managerShopId);

6.2) Create Client for refund agent

This agent accumulates the settlement of all registered shops into the settlement of the settlement-shop, and exchanges the settlement for tokens.

var refundAgentPrivateKey = "0x70438bc3ed02b5e4b76d496625cb7c06d6b7bf4362295b16fdfe91a046d4586c";
var managerShopId = "0x000108bde9ef98803841f22e8bc577a69fc47913914a8f5fa60e016aaa74bc86";
var refundAgent = new SettlementClient(network, refundAgentPrivateKey, managerShopId);

6.3) Create Client for withdrawal agent

This agent is authorized to perform the function of withdrawing tokens to the main chain.

var withdrawalAgentPrivateKey = "0x44868157d6d3524beb64c6ae41ee6c879d03c19a357dadb038fefea30e23cbab";
var managerShopId = "0x000108bde9ef98803841f22e8bc577a69fc47913914a8f5fa60e016aaa74bc86";
var withdrawalAgent = new SettlementClient(network, withdrawalAgentPrivateKey, managerShopId);

6.4) Register the refund agent

This can only be registered by the owner of the settlement-shop.

await settlementClientForManager.SetAgentOfRefund(refundAgent.Address);

6.5) Register the withdrawal agent

This can only be registered by the owner of the settlement-shop.

await settlementClientForManager.SetAgentOfWithdrawal(withdrawalAgent.Address);

6.6) Collect Settlement Amount

You have to get the number of stores first, and if the number of stores is too high, you have to do it several times.
The maximum number of stores that can be processed at once is 10.

var count = await refundAgent.GetSettlementClientLength();
var clients = await refundAgent.GetSettlementClientList(0, count);
refundAgent.CollectSettlementAmountMultiClient(clients);

6.7) Refund Settlement Amount

Exchange the settlement amount into tokens.

var refundableData = await settlementClient.GetRefundable();
await refundAgent.Refund(refundableData.RefundableAmount);

6.8) Withdrawal token

Withdraw tokens to the main chain.

var accountOfShop = await settlementClient.GetAccountOfShopOwner();
var res = await settlementClient.GetBalanceAccount(accountOfShop);
var balanceOfToken = res.Token.Balance;
await withdrawalAgent.Withdraw(balanceOfToken);

6.9) Transfer of tokens

Owners of settlement-shop can transfer tokens withdrawn to the main chain from the app to other addresses
