C# Api Client Library with OAuth2

Features

• Makes structured calls to the DigiKey API from .NET projects
• Logs in users using the OAuth2 code flow

Basic Usage

var settings = ApiClientSettings.CreateFromConfigFile();
var client = new ApiClientService(settings);
var postResponse = await client.KeywordSearch("P5555-ND");
Console.WriteLine("response is {0}", postResponse);

Project Contents

• ApiClient - Client Library that contains the code to manage a config file with OAuth2 settings and classes to do the OAuth2 call and an example call to DigiKey's KeywordSearch Api.
• ApiClient.ConsoleApp - Console app to test out programmatic refresh of access token when needed and also check if access token failed to work and then refresh and try again.
• OAuth2Service.ConsoleApp - Console app to create the initial access token and refresh token.

Getting Started

1. Download the zip file containing the solution ApiClient
2. You will need to Register an application in order to create your unique Client ID, Client Secret, and OAuth Redirection URL. Follow the steps available on the API Portal here https://developer.digikey.com/
3. In the solution folder update apiclient.config with the ClientId, ClientSecret, and RedirectUri values from step 2.

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <appSettings>
        <add key="ApiClient.ClientId"" value="YOUR_CLIENT_ID_HERE" />
        <add key="ApiClient.ClientSecret" value="YOUR_CLIENT_SECRET_HERE" />
        <add key="ApiClient.RedirectUri"  value="YOUR_REDIRECT_URI_HERE" />
        <add key="ApiClient.AccessToken" value="" />
        <add key="ApiClient.RefreshToken" value="" />
        <add key="ApiClient.ExpirationDateTime" value="" />
    </appSettings>
</configuration>

4. Run OAuth2Service.ConsoleApp to set the access token, refresh token and expiration date in apiclient.config.
5. Run ApiClient.ConsoleApp to get results from keyword search.
