dapi-csharp

A client library that talks to the Dapi API.

Quickstart

Configure Project

  1. First add the library from nuget to your project.
<PackageReference Include="Dapi" Version="1.0.0"/>
  1. Import Dapi's library in your code.
using Dapi;
using Dapi.Products;
using Dapi.Response;
using Dapi.Types;

Configure Library

  1. Create a Dapi app with your App Secret
namespace TestConsoleApp {
    public class TestClass {
        private DapiApp myApp;

        public TestClass() {
            myApp = new DapiApp("YOUR_APP_SECRET");
        }
    }
}
  1. Now you can use any of the functions of the DapiApp instance, myApp, to call Dapi with your appSecret.
namespace TestConsoleApp {
    public class TestClass {
        public void TestFunc() {
            var resp = myApp.getAccounts("YOUR_ACCESS_TOKEN", "YOUR_USER_SECRET");
            // do something with the resp
        }
    }
}
  1. Or, you can use it inside your endpoint. Our code will basically update the request to add your app's appSecret to it, and forward the request to Dapi, then return the result.
namespace TestConsoleApp {
    public class TestClass {
        public void HandlerFunc(string requestBodyJson, ICollection<KeyValuePair<string, string>> requestHeaders) {
            var resp = myApp.handleSDKRequest(requestBodyJson, requestHeaders);
            //resp = myApp.handleSDKRequest(requestBodyJson); // or with no headers
            // do something with the resp
        }
    }
}

Complete Example

You need to replace the placeholders in this code snippet(appSecret, accessToken, userSecret) with your own values, and to handle the response got.

using System.Collections.Generic;
using Dapi;
using Dapi.Products;
using Dapi.Response;
using Dapi.Types;


namespace TestConsoleApp {
    public class TestClass {
        private DapiApp myApp;

        public TestClass() {
            myApp = new DapiApp("YOUR_APP_SECRET");
        }

        public void TestFunc() {
            var resp = myApp.getAccounts("YOUR_ACCESS_TOKEN", "YOUR_USER_SECRET");
            // do something with the resp
        }

        public void HandlerFunc(string requestBodyJson, ICollection<KeyValuePair<string, string>> requestHeaders) {
            var resp = myApp.handleSDKRequest(requestBodyJson, requestHeaders);
            //resp = myApp.handleSDKRequest(requestBodyJson); // or with no headers
            // do something with the resp
        }
    }
}
