Initialize Prime Client

The following code snippet demonstrates how to initialize the Prime client:

namespace CoinbaseSdk.PrimeExample.Example
{
  using CoinbaseSdk.Core.Credentials;
  using CoinbaseSdk.Core.Serialization;
  using CoinbaseSdk.Prime.Client;

  class Example
  {
    static void Main()
    {
      string? credentialsBlob = Environment.GetEnvironmentVariable("COINBASE_PRIME_CREDENTIALS");
      if (credentialsBlob == null)
      {
        Console.WriteLine("COINBASE_PRIME_CREDENTIALS environment variable not set");
        return;
      }

      var serializer = new JsonUtility();

      var credentials = serializer.Deserialize<CoinbaseCredentials>(credentialsBlob);

      if (credentials == null)
      {
        Console.WriteLine("Failed to parse COINBASE_PRIME_CREDENTIALS environment variable");
        return;
      }

      var client = new CoinbasePrimeClient(credentials!);
    }
  }
}

Listing Portfolios

Update the code snippet with the service invocation and call to make your first API call with Prime to List Portfolios.

namespace CoinbaseSdk.PrimeExample.Example
{
  using CoinbaseSdk.Core.Credentials;
  using CoinbaseSdk.Core.Serialization;
  using CoinbaseSdk.Prime.Client;
  using CoinbaseSdk.Prime.Model;
  using CoinbaseSdk.Prime.Orders;
  using CoinbaseSdk.Prime.Portfolios;

  class Example
  {
    static void Main()
    {
      string? credentialsBlob = Environment.GetEnvironmentVariable("COINBASE_PRIME_CREDENTIALS");
      if (credentialsBlob == null)
      {
        Console.WriteLine("COINBASE_PRIME_CREDENTIALS environment variable not set");
        return;
      }

      string? portfolioId = Environment.GetEnvironmentVariable("COINBASE_PRIME_PORTFOLIO_ID");
      if (portfolioId == null)
      {
        Console.WriteLine("COINBASE_PRIME_PORTFOLIO_ID environment variable not set");
        return;
      }

      var serializer = new JsonUtility();

      var credentials = serializer.Deserialize<CoinbaseCredentials>(credentialsBlob);

      if (credentials == null)
      {
        Console.WriteLine("Failed to parse COINBASE_PRIME_CREDENTIALS environment variable");
        return;
      }

      var client = new CoinbasePrimeClient(credentials!);

      var portfoliosService = new PortfoliosService(client);

      var listPortfoliosResponse = portfoliosService.ListPortfolios();

      Console.WriteLine($"Portfolio: {serializer.Serialize(portfolio)}");
    }
  }
}

Installation

The Coinbase Prime Go SDK works with Go 1.19+

Check your Golang version:

go version

Initialize a new Go module and tidy dependencies. Run the following commands in your project directory, replacing example.com/test with a proper project directory:

go mod init example.com/test
go mod tidy
go build

Install the Golang SDK:

go get github.com/coinbase-samples/prime-sdk-go

To use the Prime Go SDK, initialize the Credentials struct and create a new client. The Credentials struct is JSON enabled. Ensure that Prime API credentials are stored in a secure manner.

There are convenience functions to read the credentials as an environment variable (prime.ReadEnvCredentials) and to deserialize the JSON structure (prime.UnmarshalCredentials) if pulled from a different source. The JSON format expected for running this SDK is:

export PRIME_CREDENTIALS='{ "accessKey": "", "passphrase": "", "signingKey": "", "portfolioId": "", "svcAccountId": "" }'

These should be stored in ~/.zshrc or ~/.bashrc. You may proceed initially without knowing your Portfolio ID or Entity ID. The SDK will return these values in the response when you make your first API call below.

Making your first API call

Initialize Prime Client

The following code snippet demonstrates how to initialize the Prime client.

package main

import (
    "net/http"

    "github.com/coinbase-samples/prime-sdk-go"
)

func main() {
    primeCredentials, err := credentials.ReadEnvCredentials("PRIME_CREDENTIALS")
    if err != nil {
        log.Fatalf("unable to load prime credentials: %v", err)
    }

    httpClient, err := client.DefaultHttpClient()
    if err != nil {
        log.Fatalf("unable to load default http client: %v", err)
    }

    client := prime.NewRestClient(primeCredentials, httpClient)
}

Listing Portfolios

Update the code snippet with the service invocation and call to make your first API call with Prime to List Portfolios.

package main

import (
    "context"
    "encoding/json"
    "log"
    "net/http"

    "github.com/coinbase-samples/prime-sdk-go"
)

func main() {
    primeCredentials, err := credentials.ReadEnvCredentials("PRIME_CREDENTIALS")
    if err != nil {
        log.Fatalf("unable to load prime credentials: %v", err)
    }

    httpClient, err := client.DefaultHttpClient()
    if err != nil {
        log.Fatalf("unable to load default http client: %v", err)
    }

    client := prime.NewRestClient(primeCredentials, httpClient)

    ctx := context.Background()
    response, err := client.ListPortfolios(ctx, &prime.ListPortfoliosRequest{})
    if err != nil {
        fmt.Println("Could not make request:", err)
        return
    }

    jsonResponse, err := json.MarshalIndent(response, "", "  ")
    if err != nil {
        log.Fatalf("Could not marshall response to JSON: %v", err)
    }
    log.Println(string(jsonResponse))
}
