To make integrations with eBay RESTful APIs easier, eBay provides client libraries in C# and Java to make it simpler to set up authorization, reduce the amount of code the application developers have to write to get OAuth Access Tokens. This library in addition to functioning as a simple eBay OAuth Client, helps with additional features such as cached App tokens.
OAuth 2.0 is the industry-standard protocol for authorization to obtain limited access to an HTTP service. All eBay RESTful APIs use the OAuth 2.0 protocol for authorization. OAuth access tokens verify to eBay that a request is coming from a valid client and that the application has the user’s authorization to carry out the requests. Learn more about the OAuth Access Tokens.
eBay OAuth Client is a class library that targets the .NET Standard 2.0. This library can be used by any .NET implementation that supports 2.0 version of the .NET Standard.

</ItemGroup>- After cloning the project, you can build the package from the source by executing following script from project directory:
- ebay-oauth-csharp-client.dll will be created at ebay-oauth-csharp-client/bin/Debug/net6.0
- Create a config YAML file in your application. The config file should contain your eBay applications keys: App Id, Cert Id & Dev Id. A sample config file is available at https://github.com/ebay/ebay-oauth-csharp-client/blob/master/Tests/ebay-config-sample.yaml. Learn more about creating application keys.
name: ebay-config
api.sandbox.ebay.com:
appid: <appid-from-developer-portal>
certid: <certid-from-developer-portal>
devid: <devid-from-developer-portal>
redirecturi: <redirect_uri-from-developer-portal>
Api.ebay.com:
appid: <appid-from-developer-portal>
certid: <certid-from-developer-portal>
devid: <devid-from-developer-portal>
redirecturi: <redirect_uri-from-developer-portal>- Once the config file is ready, use following code to load it. It is recommended to load the credentials during startup time (initialization) to prevent runtime delays.
CredentialUtil.Load(“YAML config file path”);
or
CredentialUtil.Load(System.IO.StreamReader);-
Once the credentials are loaded, call any operation on OAuth2Api.
- GetApplicationToken: Use this operation when the application request an access token to access their own resources, not on behalf of a user. Learn more about Client Credentials grant flow.
OAuth2Api.GetApplicationToken(OAuthEnvironment environment, IList<String> scopes)- GenerateUserAuthorizationUrl: Use this operation to get the Authorization URL to redirect the user to. Once the user authenticates and approves the consent, the callback needs to be captured by the redirect URL setup by the app.
OAuth2Api.GenerateUserAuthorizationUrl(OAuthEnvironment environment, IList<String> scopes, String state)- ExchangeCodeForAccessToken: Use this operation when an application exchanges an authorization code for an access token. After the user authenticates, approves the consent and returns to the application via the redirect URL , the application will get the authorization code from the URL and use it to request an access token. Learn more about Authorization Code grant flow.
OAuth2Api.ExchangeCodeForAccessToken(OAuthEnvironment environment, String code)- GetAccessToken: Usually access tokens are short lived. Use this operation to update the access token. Learn more about Using a refresh token to update the access token.
OAuth2Api.GetAccessToken(OAuthEnvironment environment, String refreshToken, IList<String> scopes)Contributions in terms of patches, features, or comments are always welcome.
