Main methods

The principal public methods exposed by the component.

Quick Start

Drop the component on a form, configure the properties below and activate it. The snippet that follows shows the typical Coinbase | Connect WebSocket API configuration sourced from the online help.

Delphi (VCL / FireMonkey)

oClient := TsgcWebSocketClient.Create(nil);
oCoinbase := TsgcWSAPI_Coinbase.Create(nil);
oCoinbase.Client := oClient;
oClient.Active := True;

C++ Builder

TsgcWebSocketClient oClient = new TsgcWebSocketClient();
TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase();
oCoinbase->Client = oClient;
oClient->Active = true;

.NET (C#)

TsgcWebSocketClient oClient = new TsgcWebSocketClient();
TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase();
oCoinbase.Client = oClient;
oClient.Active = true;

Common scenarios

The following scenarios are lifted verbatim from the online help. Each shows the configuration and method calls needed to drive the component through a specific real-world flow.

1 · Coinbase | Subscribe WebSocket Channel

Coinbase offers a variety of channels where you can subscribe to get real-time updates of market data, orders... Find below a sample of how subscribe to a Ticker:

oClient := TsgcWebSocketClient.Create(nil);
oCoinbase := TsgcWSAPI_Coinbase.Create(nil);
oCoinbase.Client := oClient;
oCoinbase.SubscribeTicker('ETH-USD');

procedure OnCoinbaseMessage(Sender: TObject; aType, aRawMessage: string);
begin
// here you will receive the ticker updates
end;

TsgcWebSocketClient oClient = new TsgcWebSocketClient();
TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase();
oCoinbase->Client = oClient;
oCoinbase->SubscribeTicker("ETH-USD");

void OnCoinbaseMessage(TObject *Sender, string aType, string aRawMessage)
{
// here you will receive the ticker updates
}

TsgcWebSocketClient oClient = new TsgcWebSocketClient();
TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase();
oCoinbase.Client = oClient;
oCoinbase.SubscribeTicker("ETH-USD");	

void OnCoinbaseMessage(TObject Sender, string aType, string aRawMessage)
{
// here you will receive the ticker updates
}

2 · Coinbase Pro SandBox Account

Coinbase allows you to use a SandBox account where you can trade without real funds. This account requires creating API keys different from the production account.

oCoinbase := TsgcWSAPI_Coinbase.Create(nil);
oCoinbase.Coinbase.ApiKey := 'your api key';
oCoinbase.Coinbase.ApiSecret := 'your api secret';
oCoinbase.Coinbase.SandBox := True;
ShowMessage(oCoinbase.REST_API.ListAccounts);

TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase(this);
oCoinbase->Coinbase->ApiKey = "your api key";
oCoinbase->Coinbase->ApiSecret = "your api secret";
oCoinbase->Coinbase->SandBox = true;
ShowMessage(oCoinbase->REST_API>ListAccounts);

TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase();
oCoinbase.Coinbase.ApiKey = "your api key";
oCoinbase.Coinbase.ApiSecret = "your api secret";
oCoinbase.Coinbase.SandBox = true;
MessageBox.Show(oCoinbase.REST_API.ListAccounts);

3 · Coinbase Pro | Get Market Data

Coinbase offers public Market Data through REST Endpoints, when you call one of these endpoints, you will get a snapshot of the market data requested.

oCoinbase := TsgcWSAPI_Coinbase.Create(nil);
ShowMessage(oCoinbase.REST_API.GetPublicProductBook('BTC-USD'));

TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase(this);
ShowMessage(oCoinbase->REST_API->GetPublicProductBook("BTC-USD"));

TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase();
MessageBox.Show(oCoinbase.REST_API.GetPublicProductBook("BTC-USD"));

4 · Coinbase Pro | Place Orders

In order to place new orders in Coinbase, you first need your API keys to access your private data. Check the following article: How to Use Private REST API.

oCoinbase := TsgcWSAPI_Coinbase.Create(nil);
oCoinbase.Coinbase.ApiKey := 'your api key';
oCoinbase.Coinbase.ApiSecret := 'your api secret';
oCoinbase.Coinbase.ApiPassphrase := 'your passphrase';
ShowMessage(oCoinbase.REST_API.PlaceMarketOrder(coisBuy, 'BTC-USD', 0.002, 0));

TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase(this);
oCoinbase->Coinbase->ApiKey = "your api key";
oCoinbase->Coinbase->ApiSecret = "your api secret";
oCoinbase->Coinbase->ApiPassphrase = "your passphrase";
ShowMessage(oCoinbase->REST_API>PlaceMarketOrder(coisBuy, "BTC-USD", 0.002</code><code class="delphi">, 0</code><code class="cpp">));

TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase();
oCoinbase.Coinbase.ApiKey = "your api key";
oCoinbase.Coinbase.ApiSecret = "your api secret";
oCoinbase.Coinbase.ApiPassphrase = "your passphrase";
MessageBox.Show(oCoinbase.REST_API.PlaceMarketOrder(coisBuy, "BTC-USD", 0.002</code><code class="delphi">, 0</code><code class="csharp">));

5 · Coinbase Pro | Private REST API

The Coinbase REST API offers public and private endpoints. The Private endpoints require that messages are signed to increase the security of transactions.

oCoinbase := TsgcWSAPI_Coinbase.Create(nil);
oCoinbase.Coinbase.ApiKey := '<your api key>';
oCoinbase.Coinbase.ApiSecret := '<your api secret>';
ShowMessage(oCoinbase.REST_API.ListAccounts);

TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase(this);
oCoinbase->Coinbase->ApiKey = "<your api key>";
oCoinbase->Coinbase->ApiSecret = "<your api secret>";
ShowMessage(oCoinbase->REST_API->ListAccounts);

TsgcWSAPI_Coinbase oCoinbase = new TsgcWSAPI_Coinbase();
oCoinbase.Coinbase.ApiKey = "<your api key>";
oCoinbase.Coinbase.ApiSecret = "<your api secret>";
MessageBox.Show(oCoinbase.REST_API.ListAccounts);
